UL, a leading global safety science company, announced today the launch of a free online database recognizing manufacturers who have completed testing under the ANSI/CAN/UL 9540A Standard for Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems (BESS). The database allows manufacturers that have had their cell, module, unit or installation evaluated for thermal runaway fire propagation by UL to share the data in three ways: the model number with contact information to obtain more test details, the UL 9540A report summary or the full test report.

Using UL’s web-based Product iQ™ platform, the UL 9540A test database allows engineers, utilities, developers, code authorities, insurers and other professionals to verify that a manufacturer’s product addresses the key issues identified by building and fire codes such as BESS installation, ventilation requirements, fire protection, and fire service strategy and tactics.

“As a test method, UL 9540A testing does not provide a certification, UL Mark, or pass/fail results,” said Maurice Johnson, business development engineer with UL’s Energy Systems and e-Mobility group. “The information from UL 9540A testing supports important safety decisions about how the BESS will be installed and used. The best way for manufacturers to share that their energy storage battery products have been tested for thermal runaway is to list them in the UL 9540A test database.”

The UL 9540A Test Method is referenced within UL 9540, the American and Canadian National Standard for Safety for Energy Storage Systems and Equipment, the International Code Council (ICC) International Fire Code (IFC), National Fire Protection Association NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, as well as a wide variety of local, state and international building and fire codes. The Test Method is intended to bring clarity about the fire safety performance of a BESS if thermal runaway were to occur in the life of the system. Since publication of the first edition in 2017, UL has worked with fire protection and battery experts, original equipment manufacturers, code authorities and other key stakeholders to enhance the test methods of UL 9540A as the established protocol for evaluating thermal runaway fire propagation in BESS in accordance with the relevant codes.

UL customer Natron Energy CEO Colin Wessells said: “Our customers require the safest batteries to power their critical database and telecom infrastructure. Natron has perfected a sodium-ion battery to pass UL’s rigorous UL 9540A fire testing. Now, we're proud to be the first battery cell company to publicly disclose our full testing results on the UL 9540A database.”

"At Enphase, product safety is paramount and the new UL 9540A Standard is critical to ensuring accountability across the storage industry,” said Raghu Belur, co-founder and chief products officer at Enphase Energy. “We are proud of our long-standing relationship with UL and appreciate the collaboration to establish standards for evaluating the safety of battery energy storage systems.”

“The UL 9540A Test Method provides critical information on battery safety that end users and authorities having jurisdiction can depend on when planning and executing energy storage deployments,” Tim Hysell, ZincFive CEO and co-founder said. “The UL 9540A Test Method includes cell level testing for qualified batteries that can be tested at the electrochemical level without additional safety controls. The fundamental safety of batteries that do not exhibit thermal runaway at the cell level is vital knowledge for the energy storage community.”

UL 4600 Draft Puts Safety Onus on AV Hopefuls

By Junko Yoshida, 10.02.19

The hype cycle of autonomous vehicles (AVs) might have already passed the peak of inflated expectations. The next step for AV vendors is to level with the public, to acknowledge that there's a critical question that still lacks an answer: How safe is safe enough?

Not coincidentally, Underwriters’ Laboratories (UL) has just released its draft of UL 4600 — the first comprehensive safety standard for autonomous products.

UL 4600 isn’t your grandfather’s rulebook. Anyone looking for technical specifications to quickly build a safe AV, will be barking up the wrong tree. UL 4600 isn’t that.

This standard lists no specifications, stipulates no hardware or software (no mandates for types of sensors, SoCs or embedded software), and provides no prescribed guidance as to the proper development process. Instead, UL 4600 offers a guide to “build the safety case” for your AV.

In short, other existing safety standards prescribe “how to do safety” by following step 1, step 2 and step 3. UL 4600, in contrast, is about “how you’ve done it [safety] enough,” explained Phil Koopman, CTO of Edge Case Research, and a professor at Carnegie Mellon University.

Asked about the basic design principles of the UL standard, Koopman, one of UL 4600’s authors, told us, “If you can't say what it means to be safe, and you can't explain why you think the system is actually safe, then probably your system is not safe.” A safety case is “an important piece of designing safe systems,” he noted.


Why another safety standard is needed
As Koopman noted, “Self-driving cars will change how we'll have to do safety compared to human-driven vehicles in some fundamental ways.” He stressed, “It should be no surprise if our approach to safety standards changes as well. But it's important not to forget the hard-won lessons and engineering approaches we already use.”

UL 4600 makes it very clear that it’s not the only safety standard AV designers need.  “You also need good engineering methods such as those discussed in other standards [including IEC 61508, ISO 26262 and ISO/PAS 21448 (SOTIF)],” said Koopman. “I expect developers will use both conventional standards such as ISO 26262 together with UL 4600.”

UL 4600 markedly differs from other safety standards in that it focuses on full autonomy, without human assistance.

 

For example, existing safety standards are designed for vehicles that ultimately have a human driver responsible for safe operation. In contrast, UL 4600 deals with full autonomy head-on. The draft standard explains, “complete removal of humans from performing aspects (including supervision) of autonomous item operation brings with it numerous additional concerns.” UL 4600 addresses these “additional concerns.”

The Complex Quest to Write a Robocar Driving Test

Self-driving cars are patrolling our roads, and it's about time someone made a proper engineering standard that they can be held to.

Self-driving cars are here,” Dmitri Dolgov told the audience at MIT Technology Review’s EmTech Digital event this week. “It's not a matter of when or if. It’s a matter of how fast we can grow and how fast we can scale this technology in a responsible manner.”

Waymo’s CTO is right: The outfit that started off as Google’s self-driving car project is running a limited robotaxi service in the Phoenix metro area. (The company still uses safety drivers, so the cars aren’t yet totally driverless. Dolgov also told the audience that the company has tech yet to crack.) And it’s not alone. GM Cruise plans to launch a service this year. Uber is testing in Pittsburgh. Lyft and Aptiv have a limited self-driving service in Las Vegas. Nuro’s delivery bots are hauling groceries around Texas and Arizona. May Mobility is running robo-shuttles in Detroit.

So for the public sharing the roads with these things, a few long lurking questions are now more pressing than ever: How do we know these things are safe? The companies say they are, but how can they prove it to us?

One thing is for sure: The way we certify human drivers ain’t going to cut it. Just because software can pull off a three-point turn once doesn’t mean it will be able to do it every time, in variable conditions. Or that the people who built it even know why it worked. Algorithms are black boxes; developers can see whether a computer is doing something right, but they can’t necessarily tell if the computer understands why it’s right. If something goes wrong with self-driving software, though, researchers are going to need to understand how it works—so they can fix it.

A different sort of test, then, is in order. One made not for people, but for machines. That’s why some people in the self-driving space are talking about setting a new kind of standard.

The WIRED Guide to Self-Driving Cars

For decades, engineers who build anything, including software, have used standards to verify the quality of their work. Whether those standards are voluntary or government mandated, they’re less rules for what to do than processes for making sure that what you do works. Underwriters Laboratory, based in Illinois, writes standards and certifies that companies are following them for just about any product you can think of: outdoor furniture, horticultural lighting and grow systems, armored cables, robotic equipment, factory-built fireplaces, tin-clad fire doors. Check your favorite American electronic product or appliance and chances are you’ll find a safety certification stamp from Underwriters or a similar organization. (If you don’t, maybe rethink your choice.) Another group called the International Organization of Standards came out with a new standard called ISO 26262 eight years ago, which outlines safety in electrical or electronic car systems.

But no one has made this kind of standard, this variety of test, for a self-driving car. Underwriters Laboratories and a safety software company called Edge Case Research would like to change that, and quickly. They have a plan to bring together all sorts of players in this budding industry to do what others have done for automotive software and those tin-clad fire doors. The groups plan to write a new safety standard for autonomous products called—and this just rolls off the tongue—UL 4600.

Right now, UL 4600 is a draft, written by collaborators with backgrounds in standards writing and aviation and automotive software tech. To make the final version, they need to bring together a “supergroup” panel of advisers. They’d like to do that this spring.

“I have a balance of interests that I look for,” says Deborah Prince, the standards process manager for Underwriters Laboratories. She has put together many advisory panels for the standards that the company oversees. “I’m looking for my producers, I might have software people in there, insurance people, regulators. I want the right cross section.” For a self-driving software standard, that cross section might be made up of big developers like Waymo and Uber, small self-driving startups, independent researchers, car companies, and maybe even a few staffers from the Department of Transportation.

 (Waymo could not say whether it has been in conversation with UL about this safety standard, but Uber spokesperson Sarah Abboud said the company was aware of UL’s activity and is “interested in getting involved in any industry standard work that brings self-driving vehicles to market in a safe, responsible way.”)

Together, the groups want that advisory panel to come up with a standard that would force those building self-driving technology to explain how their cars can get through bloopers and accidents, even without a driver at the wheel. Tire blows out? No one’s going to grab the steering wheel. Vehicle catches on fire and the passenger is asleep in the back? No one’s there to wake them up and get them out. Developers would have to lay out precisely how their software works around those autonomy-specific problems.

“The standard says, 'This is a list of all the things that it means to do the right thing, and you have to explain to me how you're going to get it right,'” says Philip Koopman, a cofounder of Edge Case Research and an electrical and computer engineering professor at Carnegie Mellon University, who is helping to write the standard. “I don't really care how. But you're not allowed to blow it off.”

The standard has a ways to go, but its makers want the process to move quickly. If the group comes together this spring, it might update the draft standard by midyear and solicit public feedback. It could even publish a standard by the end of the 2019—warp speed for a process that usually takes years.

Then, though, would come the biggest challenge: getting companies to use the thing. Because a standard without adherents is like a church without congregants—kind of depressing and not very useful. One hurdle facing the group is that Underwriters isn’t yet strongly established in the automotive space. Also, many aren’t convinced it’s not better to just rejigger ISO’s 26262 standard for autonomous driving.

But the upside for this standard—or any safety standard, really—is that following it could mean a safer self-driving car. One that’s far better than a teen who just passed his first driving test—and can prove it.

Description:

Insulation Coordination Including Clearances and Creepage Distances for Electrical Equipment

Notes:

1.1 These requirements cover an alternate approach to specifying through air and over surface spacings for electrical equipment through the use of the principles of insulation coordination.

1.2 The complete principles of insulation coordination involve the consideration of the combination of clearances, creepage distances, and the properties of solid insulation used to constitute the insulation system. The empirical data gathered thus far has been used to develop the requirements for clearances and creepage distances as presented in this standard. The data needed to develop the evaluation procedure for solid insulation is still being gathered. When available, this evaluation procedure will be added to this standard and is not expected to affect the requirements for clearances and creepage distances.

1.3 These requirements may be used as an alternate to required spacing levels specified in end-product standards. The end product standard spacing requirements may be based on use and systems where overvoltages are not controlled, or if controlled, the level of control is unknown.

1.4 These alternate requirements are intended to be applied to a particular product category if the standard covering the product category specifically references UL 840 or any of the requirements therein.

1.5 Users of these requirements may need to specify the overvoltage levels and the methods of control which will be utilized, and establish the pollution degree to which the product insulation system will be expected to be subjected.

1.6 It is not intended that the test values in this standard be employed for production line testing. However, users of these requirements will need to establish a means to ensure that production controls applied to permit the spacing reduction remain in effect during the manufacture of the product. This could include sample testing or physical measurements or another equivalent means.

1.7 Users of these requirements will additionally need to ensure that influencing factors not addressed in this standard, such as mechanical movement, field placement of conductive material, and product damage, will not affect the system for insulation coordination. Examples are the deformation of the enclosure, movement of the fittings for conduit or armored cable, or the improper installation of field wiring. Clearances and creepage distances at those locations must be verified for compliance by physical measurement in accordance with Section 10, Measurement of Clearance and Creepage Distances.

Household and Similar Electrical Appliances - Safety - Part 2-34: Particular Requirements for Motor-Compressors

Notes:

Scope

This clause of Part 1 is replaced by the following.

This International Standard deals with the safety of sealed (hermetic and semi-hermetic type) MOTOR-COMPRESSORS, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to MOTOR-COMPRESSORS tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase MOTOR-COMPRESSORS and 600 V for other MOTOR-COMPRESSORS.

1DV.1 Modification to replace the second sentence of the second paragraph in Clause 1 with the following:

It applies to motor-compressors tested separately, under the most severe conditions that can be expected to occur in normal use, their rated voltage being not more than 300 V for single-phase motor-compressors and 600 V for other motor-compressors intended for use in accordance with:

-  CSA C22.1,  Canadian Electrical Code (CE Code) Part I, in Canada;

-  NFPA 70,  National Electrical Code (NEC), in the United States.

1DV.2 Modification by adding the following to Clause 1 of the Part 2:

For MOTOR-COMPRESSORS rated greater than 600 V, see the requirements of Annex 101.dvi.

This standard also covers

- multi-speed MOTOR-COMPRESSORS, that are MOTOR-COMPRESSORS, the speed of which can be set to different values;

- variable capacity MOTOR-COMPRESSORS, that are MOTOR-COMPRESSORS where the capacity of the compressor is controlled at fixed speeds.

NOTE 101 Examples of equipment which contain MOTOR-COMPRESSORS are

- refrigerators, food freezers and ice makers (IEC 60335-2-24);

- air-conditioners, electric heat pumps and dehumidifiers (IEC 60335-2-40);

- commercial dispensing appliances and vending machines (IEC 60335-2-75);

- factory-built assemblies for transferring heat in applications for refrigerating, air-conditioning or heating purposes or a combination of such purposes.

This standard does not supersede the requirements of standards relevant to the particular appliance in which the MOTOR-COMPRESSORS is used. However, if the MOTOR-COMPRESSORS type used complies with this standard, the tests for the MOTOR-COMPRESSORS specified in the particular appliance standard may not need to be made in the particular appliance or assembly. If the MOTOR-COMPRESSORS CONTROL SYSTEM is associated with the particular appliance control system, additional tests may be necessary on the final appliance.

So far as is practical, this standard deals with the common hazards presented by MOTOR-COMPRESSORS used in appliances which are encountered by all persons in and around the home. However, it does not in general take into account

- the use of appliances by young children or infirm persons without supervision;

- playing with the appliances by young children.

NOTE 102 Attention is drawn to the fact that

- for MOTOR-COMPRESSORS intended to be used in appliances in vehicles or on board ships, additional requirements may be necessary;

- in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.

NOTE 103 This standard does not apply to

- MOTOR-COMPRESSORS designed exclusively for industrial purposes;

- motor-compressors used in appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

NOTE 104 If MOTOR-COMPRESSORS for refrigerant R-744 used in appliances with a TRANSCRITICAL REFRIGERATION SYSTEM are equipped with PRESSURE RELIEF DEVICES, compliance with the requirements for these devices is checked during the tests on the final appliance.

Description:

General Requirements for Battery-Powered Appliances

Notes:

1 Scope

1.1 This standard applies to battery operated appliances. This standard applies to appliances incorporating detachable, integral and separable battery packs. The maximum rated voltage for appliances and battery packs is 75 V d.c.

1.2 This standard also applies to battery-powered appliances that are also operated and/or charged directly from the mains or a non-isolated source, including appliances provided with integral battery chargers. The additional considerations for these constructions are contained in Additional Requirements for Battery Operated Appliances with a Connection to Mains or a Non-isolated Source, Clause 22.

1.3 These requirements are structured so as to be used in conjunction with an end product standard. These requirements are not intended to provide comprehensive evaluation of a battery operated appliance independent of an end-product standard.

1.4 These requirements only address the potential risks unique to the utilization of a battery supply in a product. With the exception of appliances that also have a mains or non-isolated source, these requirements replace or modify the requirements associated with risk of fire and electric shock for mains powered versions of the appliance in the end product standard. See Indent A in Table d1.1.

1.5 Conditions of use of the product that are the basis for test and other evaluations in the standard are retained and applied, as far as practicable, to these products employing a battery supply.

1.6 Battery operated appliances not able to be connected to mains connected power covered by this standard are not considered to be grounded (class l) or double-insulated (class II), appliances and therefore are not required to have basic, supplementary or reinforced insulation. Electric shock hazard is considered to exist only between parts of opposite polarity.

1.7 Battery packs for appliances covered under this standard intended to be charged by a non-isolated charger are to be evaluated by this standard and the requirements for protection against electric shock of the end-product standard. When evaluating a battery pack for protection against electric shock, the construction and test requirements are to be assessed with the battery fitted to the intended charger.

1.8 When evaluating the risk of fire associated with detachable battery packs, consideration has been given to the fact that these battery packs are unattended energy sources and have been evaluated as such in this standard. Detachable battery packs evaluated by this standard are therefore considered to fulfill an effective protection against the risk of fire equivalent to that of the end-product standard.

1.9 Since battery packs for appliances are submitted to different use patterns (such as rough use, high charging and discharging currents) their safety can be evaluated only by this standard and not by using other standards for battery packs, such as the Standard for Household and Commercial Batteries, UL 2054, unless otherwise indicated in this standard.

1.10 This standard does not apply to the safety of battery chargers themselves. However, this standard covers the safe functioning of lithium-ion battery systems.

1.11 This standard also addresses requirements covering the use of lithium-ion cells employed in battery systems in appliances. The following is considered within the context of these requirements:

a)    These requirements address the risk of fire or explosion of these batteries but do not cover any possible hazards associated with toxicity nor potential hazards associated with transportation or disposal.

b)    Battery systems covered by these requirements are not intended to be serviced by the end user.

c)    These requirements are intended to provide comprehensive evaluation of a battery only if used in products covered by this standard.

d)    These requirements refer to and require parameters supplied in reference to the cells that establish conditions for safe use of those cells. Those parameters form the basis of acceptance criteria for a number of tests contained herein. This standard does not independently evaluate the safety of cells. These parameters, taken as a set, constitute the “Specified Operating Region” for a cell. There may be several sets of specified operating region(s).

1.12 This standard is not intended to apply to appliances using general purpose batteries installed by the user, and this standard alone will not be sufficient to ensure all hazards are considered for these products’ “battery packs”.

1.13 These requirements do not consider the effect of special applications (such as medical appliances) or special environments (such as hazardous locations).

1.14 These requirements have not been assessed for their suitability for product categories other than appliances such as information technology equipment, telecommunications, laboratory equipment, fire alarm, security systems, emergency lighting, and audio-video apparatus, and may be incomplete with respect to those categories.

The First Comprehensive Safety Standard for Autonomous Products 

Notes:

Scope Summary

This standard covers the safety principles, risk mitigation, tools, techniques, and lifecycle processes for building and evaluating a safety argument for vehicles that can operate in an autonomous mode.

Operation is assumed to occur without human supervision and without expectation of human intervention in performing the dynamic driving task and other normal system operations environment. Human contributions to safety in other than normal operation are considered (e.g., pedestrians).

Notes:

This New Edition of ANSI/UL 4600 dated March 15, 2022 includes the following changes in requirements:

• Revise Requirements regarding Safety Case; Section 5

• Revise Requirements for Faults, Hazards, Risks; Section 6

• Revise Requirements in Assessment; Section 3

• Revise Sensor Requirements; Section 8

• Revise Requirements for Object Tracking; Section 8

• Add requirement to 7.3.1.2 to allow unconditional on demand and safe egress by authorized operator or occupant

• Terminology updates (including change in terminology of “self-audit” to “self-assessment”)

2 Scope

2 1.1 This standard covers the safety principles, risk mitigation, tools, techniques, and lifecycle processes for building and evaluating a safety argument for vehicles that can operate in an autonomous mode.

2 1.2 Operation is assumed to occur without human supervision and without expectation of human intervention in performing and supervising the dynamic driving task and other normal system operations based upon the current item state and ability to sense and otherwise interpret the operating environment. Human contributions to safety in other than normal operation are considered (e.g., maintenance), as are interactions with humans who are not operating the item (e.g., pedestrians).

2 1.3 This standard generally uses the term “ item ” rather than “system” or “product” when referring to the scope of the safety case as well as the operation of the item . This approach is in recognition of the possibility that the safety of the item might rely upon infrastructure, services, support processes, and other factors that might not normally be considered part of a system such as a vehicle per se, but which materially affect its safety and therefore are all considered within the scope of the item being assessed forconformance.

2 1.4 This standard assumes that the item autonomously operates starting at some well-defined initial state to some other well-defined end state without human intervention. Human input might influence the selection of desirable states (e.g., via an occupant requesting a destination). However, the extent to which human operators mitigate or introduce risk by performing or supervising a dynamic control task (e.g., by driving or taking responsibility for monitoring system operation) is outside the scope of the standard. Similarly, the extent to which human operator performance or non-performance is involved in risks related to transferring human driver control to or from the item is also outside the scope of the standard. However, ensuring that the item itself properly performs any change of control functions if and when it is supposed to is generally within the scope of the standard since it can adversely affect operation in fully autonomous mode as well. Thus, while portions of this standard might be helpful for addressing less than fully autonomous vehicles, issues involving human driver responsibilities, vigilance, and ability to properly accept responsibility for vehicle control are out of scope for this standard.

2 1.5 While information security is an essential topic, the details of that area are out of scope for this standard beyond a general requirement for a Security Plan and prompt elements that are possibly unique to autonomous vehicle operation in comparison to other vehicular security requirements. Reasonably foreseeable misuse and abuse as well as physical attacks (e.g., physical sensor damage) are in scope.

2 1.6 The requirements of this standard are considered to be at a necessary, but possibly not sufficient, level of completeness and rigor to create an acceptably well-formed and acceptably complete item safety case . In particular, prompt element lists are considered non-exhaustive, with an expectation that design teams will include additional items as relevant to the item and its operational design domain

2 1.1 This standard covers the safety principles, risk mitigation, tools, techniques, and lifecycle processes for building and evaluating a safety argument for vehicles that can operate in an autonomous mode, whether the item is individual or part of a team such as a platoon

2 1.2 Operation is assumed to occur without human supervision and without expectation of human intervention in performing and supervising the dynamic driving task and other normal system operations based upon the current item state and ability to sense and otherwise interpret the operating environment. Human contributions to safety in other than normal operation are considered (e.g., maintenance), as are interactions with humans who are not operating the item (e.g., pedestrians).

2 1.3 This standard generally uses the term “ item” rather than “system” or “product” when referring to the scope of the safety case as well as the operation of the item. This approach is in recognition of the possibility that the safety of the item might rely upon infrastructure, services, support processes, and other factors that might not normally be considered part of a system such as a vehicle per se, but which materially affect its safety and therefore are all considered within the scope of the item being assessed for conformance. For a team of vehicles the item might be scoped as an individual vehicle that is a member of a team or instead the item might be designed to function as a team as a whole without reducing the safety of any one vehicle.

2 1.4 This standard assumes that the item autonomously operates starting at some well-defined initial state to some other well-defined end state without human intervention. Human input might influence the selection of desirable states (e.g., via an occupant requesting a destination). However, the extent to which human operators mitigate or introduce risk by performing or supervising a dynamic control task (e.g., by driving or taking responsibility for monitoring system operation) is outside the scope of the standard. Similarly, the extent to which human operator performance or non-performance is involved in risks related to transferring human driver control to or from the item is also outside the scope of the standard. However, ensuring that the item itself properly performs any change of control functions if and when it is supposed to is generally within the scope of the standard since it can adversely affect operation in fully autonomous mode as well. Thus, while portions of this standard might be helpful for addressing less than fully autonomous vehicles, issues involving human driver responsibilities, vigilance, and ability to properly accept responsibility for vehicle control are out of scope for this standard.

2 1.5 While information security is an essential topic, the details of that area are out of scope for this standard beyond a general requirement for a Security Plan and prompt elements that are possibly unique to autonomous vehicle operation in comparison to other vehicular security requirements. Reasonably foreseeable misuse and abuse as well as physical attacks (e.g., physical sensor damage) are in scope.

2 1.6 The requirements of this standard are considered to be at a necessary, but possibly not sufficient, level of completeness and rigor to create an acceptably well-formed and acceptably complete item safety case . In particular, prompt element lists are considered non-exhaustive , with an expectation that design teams will include additional items as relevant to the item and its operational design domain

General Requirements for Battery-Powered Appliances

Notes:

1 Scope

1.1 This standard applies to battery operated appliances. This standard applies to appliances incorporating detachable, integral and separable battery packs. The maximum rated voltage for appliances and battery packs is 75 V d.c.

1.2 This standard also applies to battery-powered appliances that are also operated and/or charged directly from the mains or a non-isolated source, including appliances provided with integral battery chargers. The additional considerations for these constructions are contained in Additional Requirements for Battery Operated Appliances with a Connection to Mains or a Non-isolated Source, Clause 22.

1.3 These requirements are structured so as to be used in conjunction with an end product standard. These requirements are not intended to provide comprehensive evaluation of a battery operated appliance independent of an end-product standard.

1.4 These requirements only address the potential risks unique to the utilization of a battery supply in a product. With the exception of appliances that also have a mains or non-isolated source, these requirements replace or modify the requirements associated with risk of fire and electric shock for mains powered versions of the appliance in the end product standard. See Indent A in Table d1.1.

1.5 Conditions of use of the product that are the basis for test and other evaluations in the standard are retained and applied, as far as practicable, to these products employing a battery supply.

1.6 Battery operated appliances not able to be connected to mains connected power covered by this standard are not considered to be grounded (class l) or double-insulated (class II), appliances and therefore are not required to have basic, supplementary or reinforced insulation. Electric shock hazard is considered to exist only between parts of opposite polarity.

1.7 Battery packs for appliances covered under this standard intended to be charged by a non-isolated charger are to be evaluated by this standard and the requirements for protection against electric shock of the end-product standard. When evaluating a battery pack for protection against electric shock, the construction and test requirements are to be assessed with the battery fitted to the intended charger.

1.8 When evaluating the risk of fire associated with detachable battery packs, consideration has been given to the fact that these battery packs are unattended energy sources and have been evaluated as such in this standard. Detachable battery packs evaluated by this standard are therefore considered to fulfill an effective protection against the risk of fire equivalent to that of the end-product standard.

1.9 Since battery packs for appliances are submitted to different use patterns (such as rough use, high charging and discharging currents) their safety can be evaluated only by this standard and not by using other standards for battery packs, such as the Standard for Household and Commercial Batteries, UL 2054, unless otherwise indicated in this standard.

1.10 This standard does not apply to the safety of battery chargers themselves. However, this standard covers the safe functioning of lithium-ion battery systems.

1.11 This standard also addresses requirements covering the use of lithium-ion cells employed in battery systems in appliances. The following is considered within the context of these requirements:

a)    These requirements address the risk of fire or explosion of these batteries but do not cover any possible hazards associated with toxicity nor potential hazards associated with transportation or disposal.

b)    Battery systems covered by these requirements are not intended to be serviced by the end user.

c)    These requirements are intended to provide comprehensive evaluation of a battery only if used in products covered by this standard.

d)    These requirements refer to and require parameters supplied in reference to the cells that establish conditions for safe use of those cells. Those parameters form the basis of acceptance criteria for a number of tests contained herein. This standard does not independently evaluate the safety of cells. These parameters, taken as a set, constitute the “Specified Operating Region” for a cell. There may be several sets of specified operating region(s).

1.12 This standard is not intended to apply to appliances using general purpose batteries installed by the user, and this standard alone will not be sufficient to ensure all hazards are considered for these products’ “battery packs”.

1.13 These requirements do not consider the effect of special applications (such as medical appliances) or special environments (such as hazardous locations).

1.14 These requirements have not been assessed for their suitability for product categories other than appliances such as information technology equipment, telecommunications, laboratory equipment, fire alarm, security systems, emergency lighting, and audio-video apparatus, and may be incomplete with respect to those categories.

1.15 These requirements address the safety of battery systems during storage and use including discharge and charge. These requirements are only considered to be supplementary requirements with respect to the risk of fire and electric shock in battery chargers. The safety of battery chargers for appliances are covered by other standards such as the Standard for Power Units Other Than Class 2, UL 1012, the Standard for Battery Chargers, CAN/CSA C22.2 No. 107.2, the Standard for Class 2 Power Units, UL 1310 , the Standard for Power Supplies With Extra-Low-Voltage Class 2 Outputs, CAN/CSA C22.2 No. 223, or the Standard for Information Technology Equipment – Safety – Part 1: General Requirements, UL 60950-1 and CAN/CSA C22.2 No. 60950-1.

1.16 These requirements make frequent reference to the conditions and tests of the end-product standard while also providing minimum conditions or severity of tests. These minimum conditions are not to be construed to imply equivalence to end-product requirements. Conditions or requirements of end-product standards are to prevail over the conditions or requirements of this standard, unless otherwise indicated in this standard.

1.17 This standard is not intended to cover appliances using lithium-metal type cells, and this standard alone will not be sufficient to ensure all hazards are considered for these types of cells. Lithium-ion cells are not lithium-metal cells.

Photovoltaic (PV) Luminaire Systems

Notes:

Scope

1.1 These requirements apply to low voltage luminaire systems whose electrical power is derived from photovoltaic modules. Systems include, at a minimum, a photovoltaic (PV) module, storage batteries, one or more co-located luminaires, and controls to manage the energy flow between these subassemblies. These systems are intended to be installed in accordance with:

a) CSA C22.1, the Canadian Electrical Code (CE Code), Section 64, Renewable Energy Systems; and

b) NFPA 70, the National Electrical Code (NEC), Article 710 as a stand-alone system.

NOTE: In accordance with the CSA C22.1, 64-000(1), renewable energy systems operating within the class 2 limits of 16-200(1)(a) and (1)(b) are exempt from the requirements of Section 64.

1.2 These requirements do not address:

a) The grid-interactive systems covered by CSA C22.1, Section 64 and NFPA 70, Article 705;

b) Systems that include an inverter intended to supply line voltage luminaires or remote equipment; or

c) Individual system subassemblies (PV modules, batteries, luminaires, or controls) that have not been evaluated as a PV luminaire system.

1.3 These systems can include means to connect to and receive energy from the utility grid or similar supplemental supply source; see Annex A, Systems with Supplementary Power Connections. Systems with this feature can be installed in accordance with NEC Article 702, Optional Standby Systems.

1.4 These requirements apply to fixed-in-place systems, to portable systems that are intended to be easily relocated, and to systems intended for periodic user disassembly and storage. These requirements do not apply to handheld luminaires, such as a flashlight, or where light output is an auxiliary function of the handheld device (such as a smart phone).

1.5 These systems are intended for outdoor, exposed installations within a nominal ambient temperature range marked in accordance with 3, but no less than -20 °C to +40 °C.

1.6 These systems may include controls and devices to optimize system performance (such as sensors, positioning motors, and communication devices). They may also include output ports for diagnostic purposes or to supply temporary power to portable devices. See Annex B, Power Output Ports and Receptacles.

1.7 These requirements address only some of the mechanical infrastructure used to support or mount parts of the system. The supplemental requirements to fully evaluate the structural integrity of the mechanical infrastructure, including strength and stability of support poles under various environmental conditions such as wind or impact, and the assessment of soil or ground conditions necessary for system physical stability and reliability, are outside the scope of these requirements.

1.8 Except for components intended to connect to the utility for supplemental power in accordance with Annex A, Systems with Supplemental Power Connections, these systems are expected to operate below the 30 Vdc outdoor (wet location) class 2 voltage limits of NFPA 70 or CSA C22.1. As permitted by CSA C22.1, Section 30-1202(3) and NFPA 70, Section 411, these systems do not require grounding other than where required by Annex A. All systems are permitted to use earth ground as a reference. Any system components carrying higher voltages will require supplemental safeguards (for example, grounding or double insulation) not fully addressed within these requirements.

1.9 These requirements do not consider the vibration and other environmental conditions that may occur for systems installed on watercraft, recreational vehicles, or other mobile platforms.

1.10 These requirements do not address the required performance for certain life safety-related applications, such as for emergency signaling or emergency/egress lighting. Additional requirements from those application-specific standards should be applied to ensure the required performance expectations can be achieved. These requirements also do not address any additional considerations that may be applicable to installation in Classified (Hazardous) Locations.

1.3 These PV luminaire systems can include means to connect to and receive energy from the utility grid or similar supplemental supply source; see Annex A, Systems with Supplementary Power Connections. Systems with this feature have additionally been evaluated for conformance to the relevant aspects of NEC Article 702, Optional Standby Systems.

1.4 These requirements apply to fixed-in-place assemblies, to portable assemblies that are intended to be easily relocated, and to assemblies intended for periodic user disassembly and storage. These requirements do not apply to handheld luminaires, such as a flashlight, or where light output is an auxiliary function of the handheld device (such as a smart phone).

1.5 These assemblies are intended for outdoor, exposed installations within a nominal ambient temperature range as marked per clause 3, but no less than -20 C to +40 C.

1.6 These systems may include controls and devices to optimize system performance (such as sensors, positioning motors, and communication devices). They may also include output ports for diagnostic purposes or to supply temporary power to portable devices. See Annex B.

1.7 These requirements address some of the mechanical infrastructure used to support or mount parts of the system. However, these requirements address only those features of these mechanical systems relative to risks of electric shock, fire, injury, and property damage. The supplemental requirements to fully evaluate the structural integrity of the mechanical infrastructure, including strength and stability of support poles under various environmental conditions such as wind or impact, and the assessment of soil or ground conditions necessary for system physical stability and reliability, are outside the scope of this document.

1.8 Except for components intended to connect to the utility for supplemental power in accordance with Annex A, these systems are expected to operate below 30 Vdc, the outdoor (wet location) class 2 voltage limits of CE Code Section 16-222(3)(b) and the National Electrical Code (NEC). As permitted by CE Code 13-1202(3) (Extra-Low Voltage Lighting Systems) and NEC 411, these systems do not require grounding other than where required by Annex A. All systems are permitted to use earth ground as a reference. Any system components carrying higher voltages will require supplemental safeguards (for example, grounding or double insulation) not fully addressed within these requirements.

1.9 These requirements do not consider the vibration and other environmental conditions that may occur for systems installed on watercraft, recreational vehicles, or other mobile platforms.

1.10 These requirements do not address the required performance for certain life safety-related applications, such as for emergency signaling or emergency/egress lighting. Additional requirements from those application-specific standards should be applied to ensure the required performance expectations can be achieved. These requirements also do not address any additional considerations that may be applicable to installation in Classified (Hazardous) Locations.

Standard for Fire Test for Circuit Integrity of Fire-Resistive Power, Instrumentation, Control, and Data Cables

Notes:

Scope

1.1 The intent of this Standard is to evaluate the integrity of power, control, instrumentation, and data cables for their ability to maintain circuit integrity when subjected to standard fire test exposure and associated hose stream test.

1.2 The power, control, instrumentation, and data cables covered by this Standard are intended to comply with the following requirements :

In Canada:

Canadian Electrical Code (CEC) and the National Building Code of Canada;

In the United States:

National Electrical Code (NEC), and/or the National Fire Alarm and Signaling Code, and/or the Standard for Fixed Guideway Transit and Passenger Rail Systems, and/or the Standard for Road Tunnels, Bridges, and Other Limited Access Highways.

1.3 Power, control, and instrumentation cables are subjected to the fire exposure in accordance with CAN/ULC-S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, and ANSI/UL 263, Standard for Fire Tests of Building Construction and Materials. During the fire test, cables are continuously energized at their maximum rated voltage or maximum utilization voltage (power cables); or at their maximum utilization voltage (control and instrumentation cables) and evaluated for circuit integrity. Insulation resistance measurements are also taken to quantify leakage current. Following the fire test, the assembly shall be subjected to a hose stream test.

1.4 Data cables are subjected to the fire exposure in accordance with CAN/ULC-S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, and ANSI/UL 263, Standard for Fire Tests of Building Construction and Materials. During the fire tests, the data cables are evaluated for their ability to maintain error free data transfer and retrieval at the specified protocol and data rates. Following the fire test, the assembly shall be subjected to a hose stream test.

1.5 The fire exposure and hose stream tests are not intended to be representative of all fire conditions and impact conditions, respectively. It is likely that conditions will vary with changes in the amount, nature, distribution of fire loading, ventilation, compartment size and configuration, and heat conducting and dissipating characteristics of the compartment in which the cables are installed. These requirements provide a relative measure of fire performance of comparable assemblies under these specified fire exposure conditions. It is possible that any variation from the construction or operating condition tested, such as size, method of assembly and materials, will substantially change the performance characteristics of the cables.

1.6 The standardized fire and hose stream exposures for comparing the performance of cables represents one factor in determining the acceptability of cables for use in specific applications.

1.7 The construction and operation of the furnace and the general test conditions are intended to be in accordance with the requirements in CAN/ULC S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, and ANSI/UL 263, Standard for Fire Tests of Building Construction and Materials.

1) THE UL TEST REFERENCED IN 1 – This paragraph applies the test method described as the UL Flame Exposure (smoke measurements are not applicable) in the Standard Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685, to cable that is surface marked or designated by a marker tape as "FPL". A cable of a given construction shall not exhibit char that reaches the upper end of any specimen (a maximum of 8 ft, 0 inch or 244 cm).

2) THE FT4/IEEE 1202 TEST REFERENCED IN 1 – This paragraph applies the test method described as the FT4/IEEE 1202 Type of Flame Exposure (smoke measurements are not applicable) in the Standard Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685. This test differs from the UL tests in loading (more cables are used, with small cables bundled, and the spacing between cables or bundles is limited), burner angle, and failure criterion. For compliance, this test damages less than 150 cm (59 inches) of cable. A cable that complies either is not marked or it bears the designation "FT4/IEEE 1202" or "FT4" legible on or through the outer surface or on a marker tape [see marking in 1(i)].

Standard for Community-Antenna Television Cables

Notes:

Scope

1.1 This Standard states the construction, test, and marking requirements covering the safety of single and multiple coaxial and coaxial/optical-fiber cables for the distribution of radio frequency signals such as employed in a community antenna television system, and for supplying low-energy power at a potential not exceeding 60 volts to equipment directly associated with the signal distribution. These are power-limited cables and are of the following types for installation and use as the CATV cables specified in Article 820 and other applicable parts of the National Electrical Code (NEC), NFPA 70. Electrically nonconductive material separates each optical-fiber member from the rest of the cable.

a)  PLENUM CABLES – Type CATVP (coaxial) and Type CATVP-OF (coaxial/optical-fiber). These cables are for installation as specified in Section 820.179(A) of the National Electrical Code, ANSI/NFPA 70 in a duct, plenum, or other space used to transport environmental air without the cable being enclosed in raceway in that space.

b)  RISER CABLES – Type CATVR (coaxial) and Type CATVR-OF (coaxial/optical-fiber). These cables are for installation as specified in Section 820.179(B) of the National Electrical Code, ANSI/NFPA 70 in vertical runs in a shaft or for vertical runs that penetrate more than one floor.

c)  GENERAL-PURPOSE CABLES – Type CATV (coaxial) and Type CATV-OF (coaxial/optical-fiber). These cables are general-applications commercial cables for use as specified in Section 820.179(C) of the National Electrical Code, ANSI/NFPA 70.

d)  LIMITED-USE CABLES – Type CATVX (coaxial) and Type CATVX-OF (coaxial/optical-fiber). These are limited use cables as specified in Section 820.179(D) of the National Electrical Code, ANSI/NFPA 70.

1.2 This Standard does not specify the impedance or other signal-carrying characteristics of these cables. This Standard does not cover tests for the signal-carrying performance of these cables.

1.3 Armored cables are covered by interlocked metal strip or a smooth or corrugated metal sheath with or without a jacket over the armor. Cables for encasement in concrete, mortar, other masonry, plaster, or the like have metal armor and a jacket over the armor. Cables for direct burial in the earth (see markings in 8) are subject to a 1000-pound crushing test. Cables for direct burial are not required to be armored. Cables for direct burial that are armored have a jacket over the armor. All other cables (unarmored, flat or round) have an overall jacket. Some overall jackets incorporate a nonmetallic messenger. A metallic messenger may be joined to the cable jacket by an interconnecting web.

1.4 Cables of a CATV type do not have a voltage rating.

1.5 Cables of materials that qualify for temperatures above 60°C (140°F) are marked with a temperature rating of 75, 90, 105, 125, 150, 200°C or 250°C (167, 194, 221, 257, 302, 392°F or 482°F). Temperature marking is not required for cables that qualify for a temperature rating of 60°C (140°F).

1.6 Cables that contain one or more electromagnetic shields in addition to the outer conductors of the coaxial members (these shields are identified as "additional" in 1) are not required to be marked to indicate the presence of the additional shielding. A shielded cable that is marked has "shielded" on the tag and either on the overall cable jacket or legible through the jacket.

1.7 Cables that qualify for exposure to sunlight (720-hour sunlight-resistance test – see 1) have the designation "sun res" or "sunlight resistant" on the tag and either on the overall cable jacket or legible through the jacket.

1.8 Cables that qualify for burial directly in the earth (1000-pound crushing test – see 1) have the designation "dir bur", "direct burial", or "for direct burial" on the tag and either on the overall cable jacket or legible through the jacket.

1.9 Optical performance is not evaluated. Cables with optical fibers are to have a tag marking in accordance with 3 and 1(d). Where there are conductive parts in an optical-fiber member or in a group of such members, a tag marking [1(e)] indicates the presence of these parts.

1.10 These requirements do not cover antenna-rotator or other coaxial/electrical cables - that is, coaxial cables with additional conductors for electric-light, power, control, non-power-limited fire-alarm, Class 1, Class 2, or Class 3 circuits.

1.11 Smoke and flame tests are as follows for the cables covered in these requirements:

a) PLENUM CABLES – All Type CATVP and Type CATVP-OF cables are tested for smoke and flame characteristics as specified in Smoke and Flame Testing of Plenum Cables, Section 22, which references the National Fire Protection Association Standard Method of Test for Flame Travel and Smoke of Wires and Cables for Use in Air-Handling Spaces, ANSI/NFPA 262.

Cables covered by these requirements are:

a) Type FPLP (plenum cable),

b) Type FPLR (riser cable), and

c) Type FPL (cable for other than plenum and riser uses in general and in trays).

1.2 The cables covered in these requirements are rated for 300 volts but are not so marked. See 1(h).

1.3 A cable that contains one or more electromagnetic shields may be surface marked or have a marker tape to indicate that it is "shielded". A cable that contains one or more optical-fiber members has "-OF" supplementing the type letters and is marked in accordance with 1(d). A cable may consist of or contain one or more coaxial members.

1.4 The overall jacket on a cable that has "sun res" or "sunlight resistant" in a surface marking or on a marker tape complies with a 720-h sunlight-resistance test.

1.5 A cable that has "dir bur", "direct burial", or "for direct burial" in a surface marking or on a marker tape complies with a 1000-lbf crushing test. Direct-burial cable with wire armor, a metal braid, interlocked metal armor, or a smooth or corrugated metal sheath has a jacket over the metal covering.

1.6 Smoke and fire considerations are as follows for the cables covered in these requirements:

a) TYPE FPLP CABLE – Cable that is intended for installation in accordance with section 760-154(A) of the National Electrical Code (ANSI/NFPA 70) in a duct, plenum, or other space used to transport environmental air without the cable being enclosed in a raceway in that space is to be tested for smoke and flame characteristics in accordance with the National Fire Protection Association Standard Method of Test for Flame Travel and Smoke of Wires and Cables for Use in Air-Handling Spaces, ANSI/NFPA 262. A cable that complies exhibits a maximum flame-propagation distance that is not greater than 5 ft, 0 inch or 152 cm, a peak optical density of smoke produced of 0.50 or less (32 percent light transmission), and an average optical density of smoke produced of 0.15 or less.

b) TYPE FPLR CABLE – Cable that is intended for use in vertical runs in a shaft, or for installations in which the cable penetrates more than one floor, as specified in section 760-154(B) of the National Electrical Code ANSI/NFPA 70. This cable is to be tested for flame-propagation characteristics in accordance with the Standard Test for Flame Propagation Height of Electrical and Optical-Fiber Cables Installed Vertically in Shafts, UL 1666. A cable that complies has a flame-propagation height less than 12 ft, 0 inch or 366 cm and temperatures are 850.0°F (454.4°C) or less at a height of 12 ft, 0 inch or 366 cm.

c) TYPE FPL CABLE – Type FPL cable complies with a 70,000 Btu/h (20.5 kW) vertical-tray flame test. The cable manufacturer chooses one of the following tests:

Notes:

Summary of Topics

This new Third Edition of ANSI/UL 1655 dated October 23, 2024 incorporates editorial changes including renumbering and reformatting to align with current style.

Scope

1.1 This Standard states the construction, test, and marking requirements covering the safety of single and multiple coaxial and coaxial/optical-fiber cables for the distribution of radio frequency signals such as employed in a community antenna television system, and for supplying low-energy power at a potential not exceeding 60 volts to equipment directly associated with the signal distribution. These are power-limited cables and are of the following types for installation and use as the CATV cables specified in Article 820 and other applicable parts of the National Electrical Code (NEC), NFPA 70. Electrically nonconductive material separates each optical-fiber member from the rest of the cable.

a)  PLENUM CABLES – Type CATVP (coaxial) and Type CATVP-OF (coaxial/optical-fiber). These cables are for installation as specified in Section 820.179(A) of the National Electrical Code, ANSI/NFPA 70 in a duct, plenum, or other space used to transport environmental air without the cable being enclosed in raceway in that space.

b)  RISER CABLES – Type CATVR (coaxial) and Type CATVR-OF (coaxial/optical-fiber). These cables are for installation as specified in Section 820.179(B) of the National Electrical Code, ANSI/NFPA 70 in vertical runs in a shaft or for vertical runs that penetrate more than one floor.

c)  GENERAL-PURPOSE CABLES – Type CATV (coaxial) and Type CATV-OF (coaxial/optical-fiber). These cables are general-applications commercial cables for use as specified in Section 820.179(C) of the National Electrical Code, ANSI/NFPA 70.

d)  LIMITED-USE CABLES – Type CATVX (coaxial) and Type CATVX-OF (coaxial/optical-fiber). These are limited use cables as specified in Section 820.179(D) of the National Electrical Code, ANSI/NFPA 70.

1.2 This Standard does not specify the impedance or other signal-carrying characteristics of these cables. This Standard does not cover tests for the signal-carrying performance of these cables.

1.3 Armored cables are covered by interlocked metal strip or a smooth or corrugated metal sheath with or without a jacket over the armor. Cables for encasement in concrete, mortar, other masonry, plaster, or the like have metal armor and a jacket over the armor. Cables for direct burial in the earth (see markings in 8) are subject to a 1000-pound crushing test. Cables for direct burial are not required to be armored. Cables for direct burial that are armored have a jacket over the armor. All other cables (unarmored, flat or round) have an overall jacket. Some overall jackets incorporate a nonmetallic messenger. A metallic messenger may be joined to the cable jacket by an interconnecting web.

1.4 Cables of a CATV type do not have a voltage rating.

1.5 Cables of materials that qualify for temperatures above 60°C (140°F) are marked with a temperature rating of 75, 90, 105, 125, 150, 200°C or 250°C (167, 194, 221, 257, 302, 392°F or 482°F). Temperature marking is not required for cables that qualify for a temperature rating of 60°C (140°F).

1.6 Cables that contain one or more electromagnetic shields in addition to the outer conductors of the coaxial members (these shields are identified as "additional" in 1) are not required to be marked to indicate the presence of the additional shielding. A shielded cable that is marked has "shielded" on the tag and either on the overall cable jacket or legible through the jacket.

1.7 Cables that qualify for exposure to sunlight (720-hour sunlight-resistance test – see 1) have the designation "sun res" or "sunlight resistant" on the tag and either on the overall cable jacket or legible through the jacket.

1.8 Cables that qualify for burial directly in the earth (1000-pound crushing test – see 1) have the designation "dir bur", "direct burial", or "for direct burial" on the tag and either on the overall cable jacket or legible through the jacket.

1.9 Optical performance is not evaluated. Cables with optical fibers are to have a tag marking in accordance with 3 and 1(d). Where there are conductive parts in an optical-fiber member or in a group of such members, a tag marking [1(e)] indicates the presence of these parts.

1.10 These requirements do not cover antenna-rotator or other coaxial/electrical cables - that is, coaxial cables with additional conductors for electric-light, power, control, non-power-limited fire-alarm, Class 1, Class 2, or Class 3 circuits.

1.11 Smoke and flame tests are as follows for the cables covered in these requirements:

a) PLENUM CABLES – All Type CATVP and Type CATVP-OF cables are tested for smoke and flame characteristics as specified in Smoke and Flame Testing of Plenum Cables, Section 22, which references the National Fire Protection Association Standard Method of Test for Flame Travel and Smoke of Wires and Cables for Use in Air-Handling Spaces, ANSI/NFPA 262.

Standard for Fire Test for Circuit Integrity of Fire-Resistive Power, Instrumentation, Control, and Data Cables

Notes:

Scope

1.1 The intent of this Standard is to evaluate the integrity of power, control, instrumentation, and data cables for their ability to maintain circuit integrity when subjected to standard fire test exposure and associated hose stream test.

1.2 The power, control, instrumentation, and data cables covered by this Standard are intended to comply with the following requirements :

In Canada:

Canadian Electrical Code (CEC) and the National Building Code of Canada;

In the United States:

National Electrical Code (NEC), and/or the National Fire Alarm and Signaling Code, and/or the Standard for Fixed Guideway Transit and Passenger Rail Systems, and/or the Standard for Road Tunnels, Bridges, and Other Limited Access Highways.

1.3 Power, control, and instrumentation cables are subjected to the fire exposure in accordance with CAN/ULC-S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, and ANSI/UL 263, Standard for Fire Tests of Building Construction and Materials. During the fire test, cables are continuously energized at their maximum rated voltage or maximum utilization voltage (power cables); or at their maximum utilization voltage (control and instrumentation cables) and evaluated for circuit integrity. Insulation resistance measurements are also taken to quantify leakage current. Following the fire test, the assembly shall be subjected to a hose stream test.

1.4 Data cables are subjected to the fire exposure in accordance with CAN/ULC-S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, and ANSI/UL 263, Standard for Fire Tests of Building Construction and Materials. During the fire tests, the data cables are evaluated for their ability to maintain error free data transfer and retrieval at the specified protocol and data rates. Following the fire test, the assembly shall be subjected to a hose stream test.

1.5 The fire exposure and hose stream tests are not intended to be representative of all fire conditions and impact conditions, respectively. It is likely that conditions will vary with changes in the amount, nature, distribution of fire loading, ventilation, compartment size and configuration, and heat conducting and dissipating characteristics of the compartment in which the cables are installed. These requirements provide a relative measure of fire performance of comparable assemblies under these specified fire exposure conditions. It is possible that any variation from the construction or operating condition tested, such as size, method of assembly and materials, will substantially change the performance characteristics of the cables.

1.6 The standardized fire and hose stream exposures for comparing the performance of cables represents one factor in determining the acceptability of cables for use in specific applications.

1.7 The construction and operation of the furnace and the general test conditions are intended to be in accordance with the requirements in CAN/ULC S101, Standard Methods of Fire Endurance Tests of Building Construction and Materials, and ANSI/UL 263, Standard for Fire Tests of Building Construction and Materials.

Notes:

Scope

1.1 This Outline of Investigation specifies requirements for Fault-Managed Power Systems (FMPS), also referred to in the National Electrical Code, ANSI/NFPA 70 as “Class 4 Power Systems”. These systems are characterized by sophisticated monitoring and control systems that monitor the circuit for faults and control the power transmitted to ensure that the energy delivered into a fault is limited. Class 4 power systems differ from Class 2, and Class 3 systems. Class 4 power systems are not power limited at the source but are power limited with respect to risk of electric shock and fire hazards between the output of the Class 4 Transmitter and input of the Class 4 Receiver.

NOTE: The term “Class 4” and “FMPS” are used interchangeably throughout this Outline.

1.2 This Outline of Investigation is applicable to Class 4 equipment and circuits designed to be installed and used in accordance with Article 726 of the National Electrical Code, ANSI/NFPA 70.

1.3 In addition to the requirements in this Outline, a Fault Managed Power System shall comply with the relevant requirements of the Standard for Audio/Video, Information and Communication Technology Equipment – Part 1: Safety Requirements, UL 62368-1. Wherever there is a conflict between the requirements of this Outline and UL 62368-1, the requirements of this Outline shall apply.

1.4 This Outline is also applicable to Class 4 receivers that are integrated into other utilization equipment. This equipment shall also comply with the corresponding applicable Standard for the utilization equipment in question.

NOTE: Annex E documents decisions made by the developers of this Outline for Edition 1. This is intended to provide an understanding and background for future revisions as the technology for FMPS evolves.

Notes:

Scope

This part of IEC 60947 applies to the types of equipment listed in 1 and 2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.

Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 4) forms part of the installation but not necessarily of the contactor or the starter.

In this context, this standard gives requirements for:

– contactors associated with overload and/or short-circuit protective devices;

– starters associated with separate short-circuit protective devices and/or with separate short-circuit and integrated overload protective devices;

– contactors or starters combined, under specified conditions, with their own short-circuit protective devices. Such combinations, e.g. combination starters or protected starters are rated as units.

For circuit-breakers and fuse-combination units used as short-circuit protective devices in combination starters and in protected starters, the requirements of IEC 60947-2 and IEC 60947-3 respectively apply.

Equipment covered by this standard is as follows.

This equipment is intended for installation in accordance with CSA C22.1, Canadian Electrical Code (CE Code, Part I), and the US National Electrical Code (NEC), NFPA 70.

AC and DC contactors intended for closing and opening electric circuits and, if combined with suitable relays (see 2), for protecting these circuits against operating overloads which may occur therein.

NOTE For contactors combined with suitable relays and which are intended to provide short-circuit protection, the relevant conditions specified for circuit-breakers (IEC 60947-2) additionally apply.

This standard applies also to the actuators of contactor relays and to the contacts dedicated exclusively to the coil circuit of a contactor.

Contactors or starters with an electronically controlled electromagnet are also covered by this standard.

This standard also applies to manual controllers and combination motor controllers. See Annex DVC for specific requirements.

Notes:

Scope

This standard applies to a.c. semiconductor motor controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c.

This standard characterizes a.c. semiconductor motor controllers and starters with and without bypass means.

AC semiconductor motor controllers and starters dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 4) should form part of the installation, but not necessarily of the a.c. semiconductor motor controller or starter.

In this context, this standard gives requirements for a.c. semiconductor motor controllers and starters associated with separate short-circuit protective devices.

This standard does not apply to

– continuous operation of a.c. motors at motor speeds other than the normal speed;

– semiconductor equipment, including semiconductor contactors (see 2.2.13 of IEC 60947-1:2007) controlling non-motor loads;

– electronic a.c. power controllers covered by IEC 60146 series.

Contactors, overload relays and control circuit devices used in a.c. semiconductor motor controllers and starters should comply with the requirements of their relevant product standard. Where mechanical switching devices are used, they should meet the requirements of their own IEC product standard, and the additional requirements of this standard.

The object of this standard is to state as follows:

– the characteristics of a.c. semiconductor motor controllers and starters and associated equipment;

– the conditions with which a.c. semiconductor motor controllers and starters comply with reference to

a) their operation and behaviour;

b) their dielectric properties;

c) the degrees of protection provided by their enclosures where applicable;

d) their construction;

– the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests;

– the information to be given with the equipment, or in the manufacturer's literature.

NOTE For the purpose of this standard, the term "controller" may be used instead of "a.c. semiconductor motor controller".

Summary of Topics

The Third Edition of UL 9540 dated June 28, 2023 has been issued to reflect the latest ANSI and SCC approval dates, and to incorporate the proposals dated April 29, 2022, October 7, 2022 and February 24, 2023.

Scope

1.1 These requirements cover an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard. The ESS shall be constructed either as one unitary complete piece of equipment or as matched assemblies, that when connected, in accordance with the manufacturer’s installation instructions, form the ESS. An ESS consists of at least an energy storage function and energy storage protective function. If the ESS includes multiple parts that are housed in separate enclosures, it shall be considered as a multi-part ESS covered by this Standard. Individual parts (e.g. power conversion equipment, a battery, etc.) of an ESS are not considered an ESS on their own. This Standard evaluates the compatibility and safety of these various components and parts integrated into an ESS. The ESS can be an AC ESS or a DC ESS as defined in this Standard.

1.2 The systems covered by this Standard include those intended to be used in a standalone mode (e.g. islanded) including "self-supply" systems to provide electrical energy and those used in parallel with an electric power system or electric utility grid such as "grid-supply" systems, or applications that perform ancillary operational modes associated with power generation such as voltage support and regulation, frequency support and regulation, volt-var, capacity reserve, energy shifting or other utility grid support services.

1.3 Energy storage systems are intended for installation and use in accordance with the National Electrical Code, NFPA 70, the Canadian Electrical Code, Part I Safety Standard for Electrical Installations, CSA C22.1, the National Electrical Safety Code, IEEE C2, the International Fire Code, ICC IFC, the International Residential Code, ICC IRC, the National Fire Code of Canada, NRC NFC, the Fire Code, NFPA 1, and the Standard for the Installation of Stationary Energy Storage Systems, NFPA 855. Requirements for installation, with the exception of installation manuals and documents for installation provided with the system are outside the scope of this Standard.

1.4 This Standard covers energy storage systems for stationary indoor and outdoor installations. This Standard also covers mobile energy storage systems as defined by this Standard. This Standard includes requirements for energy storage systems used in residential and non-residential installations.

1.5 Systems using lead acid or Ni-cad batteries that fall within the scope of UL 1778/CSA C22.2 No. 107.3 and only serve an uninterruptible power system (UPS) application are outside the scope of this Standard.

NOTE: UL 1778/CSA C22.2 No. 107.3 is applicable to UPS that employ chemistries other than lead acid or Ni-cad, but the fire codes and the ESS installation standard do not exclude UPS applications from ESS criteria including compliance to this Standard for these other chemistries.

1.6 The maximum energy capacity of individual electrochemical ESS shall be determined by the following in (a) – (d). Where the results of testing are used, the results shall be determined in accordance with the Standard for Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems, UL 9540A:

  1. a) The maximum energy capacity of residential use electrochemical ESS shall not exceed 20 kWh (72 MJ). This value shall be permitted to be increased to the value of the unit which meets the performance criteria of the UL 9540A Unit Level test;

  2. b) The maximum energy capacity of non-residential use electrochemical ESS shall not exceed 50 kWh (180 MJ). This value shall be permitted to be increased to the value of the unit which meets the performance criteria of the UL 9540A Installation Level test, provided the ESS is marked in accordance with 20;

  3. c) There is no maximum energy capacity limit for non-residential use electrochemical ESS that are tested in accordance with UL 9540A in which the performance level criteria of the cell level test have been met; and

  4. d) There is no maximum energy capacity limit for non-residential use electrochemical ESS intended for use in remote outdoor locations as defined in the applicable installation code, provided they are marked in accordance with 21.

NOTE 1: The Standard for the Installation of Stationary Energy Storage Systems, NFPA 855 defines outdoor remote locations as being located more than 30.5 m (100 ft) from exposures.

NOTE 2: Lead acid, Ni-Cad, Ni-MH, and Ni-Zn ESS have exceptions to the capacity energy limits including, in some cases, no limits based upon specific telecom and utility installations as outlined in NFPA 855.

Please note that the National Difference document incorporates all of the U.S. national differences for UL 61010-2-201.

Scope and object

This clause of Part 1 is applicable, except as follows.

1.1.1 Equipment included in scope

Replacement:

• This part of IEC 61010 specifies safety requirements and related verification tests for any product performing the function of control equipment and/or their associated peripherals. In addition, these products have as their intended use the command and control of machines, automated manufacturing and industrial processes, e.g. discrete and continuous control. Some equipment examples are: programmable logic controller (PLC);

• programmable automation controller (PAC);

• distributed control systems (DCS);

• remote I/O;

• industrial PC (computers) and panel PC;

• programming and debugging tools (PADTs);

• displays and human-machine interfaces (HMI);

• positioners.

Components of the above named equipment and in the scope of this standard are:

• (auxiliary) stand-alone power supplies;

• peripherals such as digital and analogue I/O, remote-I/O;

• industrial network equipment.

Control equipment and their associated peripherals are intended to be used in an industrial environment and may be provided as OPEN or ENCLOSED EQUIPMENT.

NOTE 1 Control equipment intended also for use in other environments or for other purposes (example: for use in building installations to control light or other electrical installations, or for use on cars, trains or ships) can have additional conformity requirements defined by the safety standard(s) for these applications. These requirements can involve as example: insulation, spacings and power restrictions.

NOTE 2 Computing devices and similar equipment within the scope of IEC 60950 (planned to be replaced by IEC 62368) and conforming to its requirements are considered to be suitable for use with control equipment within the scope of this standard. However, some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in IEC 61010-1:2010, 5.4.4 second paragraph.

Control equipment covered in this standard is intended for use in OVERVOLTAGE CATEGORY II, III and IV (IEC 60664-1) in low-voltage installations, where the RATED equipment supply voltage does not exceed AC. 1 000 V r.m.s. (50/60 Hz), or DC 1 000 V.

The requirements of ISO/IEC Guide 51 and IEC Guide 104, as they relate to this part of IEC 61010, are incorporated herein.

1.1.2 Equipment excluded from scope

Replacement:

This standard does not deal with aspects of the overall automated system, e.g. a complete assembly line. Control equipment (e.g. DCS and PLC), their application program and their associated peripherals are considered as components (components in this context are items which perform no useful function by themselves) of an overall automated system.

Since control equipment (e.g. DCS and PLC) are component devices, safety considerations for the overall automated system including installation and application are beyond the scope of this standard. Refer to IEC 60364 series of standards or applicable national/local regulations for electrical installation and guidelines.

1.2.1 Aspects included in scope

Replacement:

The purpose of the requirements of this standard is to ensure that all HAZARDs to the OPERATOR, SERVICE PERSONNEL and the surrounding area are reduced to a tolerable level.

NOTE 1 By using the terms "OPERATOR" and "SERVICE PERSONNEL" this standard considers the perception of HAZARDS depending on training and skills. Annex aa gives a general approach in this regard.

Requirements for protection against particular types of HAZARD are given in Clauses 6 to 17, as follows:

a) electric shock or burn (see Clause 6);

b) mechanical HAZARDS (see Clauses 7 and 8);

c) spread of fire from the control equipment (see Clause 9);

d) excessive temperature (see Clause 10);

e) effects of fluids and fluid pressure (see Clause 11);

f) effects of radiation, including lasers sources, and sonic and ultrasonic pressure (see Clause 12);

g) liberated gases, explosion and implosion (see Clause 13);

h) arising from REASONABLY FORESEEABLE MISUSE and ergonomic factors are specified in (see Clause 16);

i) RISK assessment for HAZARDS or environments not fully covered above (see Clause 17).

NOTE 2 Attention is drawn to the existence of additional requirements regarding the health and safety of labour forces.

1.2.2 Aspects excluded from scope

Replacement:

This standard does not cover:

a) reliability, functionality, performance, or other properties of the control equipment not related to safety;

b) mechanical or climatic requirements for operation, transport or storage;

c) EMC requirements (see e.g. IEC 61326 or IEC 61131-2);

d) protective measures for explosive atmospheres (see e.g. IEC 60079 series);

e) functional safety (see e.g. IEC 61508, IEC 61131-6).

Summary of Topics

This revision of ANSI/UL 61010-2-011 dated November 2, 2023 adds requirements for refrigeration systems over 150 g of flammable refrigerant and transcritical systems; 1.1.1.1.1.1DV.1 , 1.1.2.1.1.2DV and 2.2DV

UL 61010-2-011 is an Adoption of IEC 61010-2-011, Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use – Part 011: Particular Requirements for Refrigerating Equipment (second edition, issued by IEC March 2019) as an IEC-based UL Standard with US National Differences.

Scope and object

This clause of Part 1 is applicable, except as follows:

Replacement:

Replace the second paragraph by the following:

This Part 2 of IEC 61010 specifies particular safety requirements for the following types a) to c) of electrical equipment and their accessories, wherever they are intended to be used, whenever that equipment incorporates

REFRIGERATING SYSTEMS

as an integral part of, or separate from, the equipment and the equipment is in direct control of the

REFRIGERATING SYSTEM

This document details all the requirements when up to 150 g of

FLAMMABLE REFRIGERANT

are used per stage of a

REFRIGERATING SYSTEM

. Additional requirements beyond the current scope of this document apply if a

REFRIGERANT

charge of

FLAMMABLE REFRIGERANT

exceeds this amount.

Addition:

Add the following text after the last paragraph:

NOTE 101 Examples for

REFRIGERATING EQUIPMENT

include, but are not limited to, laboratory equipment such as laboratory refrigerators, freezers, refrigerated display cabinets.

It is possible that all or part of the equipment falls within the scope of one or more other Part 2 standards of IEC 61010 as well as within the scope of this standard. In that case, the requirements of those other Part 2 standards will also apply. In particular, if equipment is intended to be used as a centrifuge, the requirements of IEC 61010-2-020 apply. However, when the equipment incorporates a refrigerating system and a heating function where the combination of the two introduces additional or more severe

HAZARDS

than if treated separately, then it is possible that IEC 61010-2-012 is applicable instead of this Part 2-011.

Standard for Definitions and Information Pertaining to Electrical Equipment in Hazardous Locations

Notes:

Scope

2.1 This document provides general guidance for safe design, installation, and maintenance of electrical equipment in hazardous (classified) locations using appropriate means to prevent ignition of flammable gases and vapors, flammable liquids, combustible dusts, or ignitable fibers or flyings.

2.2 This document covers only locations made hazardous, or potentially hazardous, due to the presence of flammable gases or vapors, flammable liquids, combustible dusts, or ignitable fibers or flyings. The document is not necessarily relevant to the hazards posed by pyrophoric materials, explosives or propellants containing their own oxidizers.

2.3 This document is concerned only with design, manufacture, installation, maintenance, and test criteria related to arcs, sparks, or hot surfaces produced by electrical and non-electrical* equipment that may cause ignition of flammable gas or vapor-in-air mixtures, clouds or blankets of combustible dust, or easily ignitable fibers or flyings. Equipment is also required to comply with the applicable ordinary location requirements (e.g.,UL 508 and UL 61010-1) either by direct reference in hazardous locations standards or by other regulations.

* Under development (Mechanical and ESD for example). Some equipment may produce static electricity or cause high temperatures or sparks due to mechanical failure. The materials of construction of parts in such equipment will be an important consideration for application in hazardous locations.

2.4 This document does not cover mechanisms of ignition from external sources, such as static electricity or lightning. Some equipment may produce static electricity. The materials of construction of parts in such equipment will be an important consideration for application in hazardous locations. The extra precautions necessary for this are beyond the scope of this document.

2.5 This document does not consider the effects of installation in corrosive atmospheres and the resulting deleterious conditions to the original design integrity of the equipment. The additional precautions necessary for these conditions are outside the scope of this document.

2.6 This document is not an instruction manual. However, it is intended to provide introductory guidance to those involved with the design, manufacture, installation, and maintenance of equipment used in hazardous (classified) locations. It is also intended to promote uniformity of practice among those skilled in the art. Nothing contained in this document is to be construed as a fixed rule without regard to sound engineering judgment.

2.7 For hazardous location equipment, atmospheric conditions are generally considered to be:

a) an ambient temperature range of -20°C (-4°F) to 40°C (104°F) for zones and to -25°C (-13°F) to +40°C (104°F) for divisions;

b) air with normal oxygen content, typically 21 percent by volume; and

c) a pressure of 80 kPa (11.6 psia) to 110 kPa (16 psia).

NOTE Equipment specified for atmospheric conditions beyond the above is generally permitted but may be subjected to additional requirements.

2.8 Specialized industries such as, but not limited to, mining and shipping may be regulated by the specific authority having jurisdiction. This document does not include specific requirements or the rules and regulations unique to any specific industry.

2.9 Various organizations have developed codes, guides, and standards that have substantial acceptance by industry and governmental bodies. Codes, guides, and standards useful in the design and installation of electrical instruments in hazardous (classified) locations are listed in Annex C. These are not considered to be a part of this document except for those specific sections of documents referenced elsewhere in this document.

2.10 In accordance with the purpose of this document, an attempt was made to avoid originality in principles whenever possible, but rather to utilize definitions, explanations, etc., from accepted publications. As a result, much of the material, except for minor changes, is directly as published by others. While specific credit is not given for each reference, all references are included in Annex B.

and current probes.

Current sensors are hand-manipulated before and/or after a test or measurement, but do not necessarily need to be

HAND-HELD

during the test or measurement. Current sensors used as

FIXED EQUIPMENT

are not within the scope of this document.

The following types of current sensors are covered:

a) Type A: a current sensor designed to be applied to or removed from

HAZARDOUS LIVE UNINSULATED CONDUCTORS

. Type A current sensors have defined

HAND-HELD

or hand-manipulated parts providing protection against electric shock from the conductor being measured, and also have protection against short-circuits between wires and between busbars during clamping.

b) Type B: a current sensor which has protection against short-circuits between wires or busbars during clamping but without defined

HAND-HELD

or hand-manipulated parts which provide protection against electric shock during clamping. Additional protective means are necessary to avoid electric shock from

HAZARDOUS LIVE

conductors which cannot be de-energised during application or removal of the current sensor.

Description:

Standard for Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use - Part 2-032: Particular Requirements for Hand-Held and Hand-Manipulated Current Sensors for Electrical Test and Measurement

Notes:

This clause of Part 1 is applicable except as follows:

Replace the existing text with the following: This part of IEC 61010 specifies safety requirements for HAND-HELD and hand-manipulated current sensors described below.

These current sensors are for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of the circuit being measured. They can be stand-alone current sensors or accessories to other equipment or parts of combined equipment (see ). These include measurement circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. These current sensors and circuits need additional protective means between the current sensor, the circuit and an OPERATOR.

NOTE 1 Combined equipment is equipment that is electrically connected to a current sensor by means of a permanent connection which can be detached only by the use of a TOOL.

NOTE 2 Some current sensors are also known as current clamps, CLAMP MULTIMETERS and current probes.

Current sensors are hand-manipulated before and/or after a test or measurement, but do not necessarily need to be HAND-HELD during the test or measurement. Current sensors used as FIXED EQUIPMENT are not within the scope of this document.

The following types of current sensors are covered:

a) Type A: a current sensor designed to be applied to or removed from

HAZARDOUS LIVE UNINSULATED CONDUCTORS. Type A current sensors have defined HAND-HELD or hand-manipulated parts providing protection against electric shock from the conductor being measured, and also have protection against short-circuits between wires and between busbars during clamping.

b) Type B: a current sensor which has protection against short-circuits between wires or busbars during clamping but without defined HAND-HELD or hand-manipulated parts which provide protection against electric shock during clamping. Additional protective means are necessary to avoid electric shock from HAZARDOUS LIVE conductors which cannot be de-energised during application or removal of the current sensor.

EXAMPLE 1 Flexible current sensors.

c) Type C: a current sensor without protection against short-circuits between wires or busbars during clamping. Type C current sensors are intended to be applied to or removed from

HAZARDOUS LIVE UNINSULATED CONDUCTORS or from non-limited-energy circuit conductors only when they are de-energised.

EXAMPLE 2 Split-core transducers.

d) Type D: a current sensor designed to be applied to or removed from insulated conductors or from limited-energy circuit conductors.

Explosive Atmospheres - Part 25: Intrinsically Safe Electrical Systems

Notes:

Scope

This part of IEC 60079 standard contains the specific requirements for construction and assessment of intrinsically safe electrical systems, type of protection “i”, intended for use, as a whole or in part, in Class I, Zone 0, 1, or 2, or Zone 20, 21, or 22 hazardous (classified) locations as defined by the National Electrical Code® (NEC), ANSI/NFPA 70® in locations in which the use of Group I, II or III apparatus is required

NOTE 1 This standard is intended for use by the designer of the system who may be a manufacturer, a specialist consultant or a member of the end-user’s staff.

This standard supplements and modifies the general requirements of ANSI/ISA-60079-0 and ANSI/ISA-61241-0

IEC 60079-0 and the intrinsic safety standard ANSI/ISA-60079-11 and ANSI/ISA-61241-11

IEC 60079-11. Where a requirement of this standard conflicts with a requirement of  ANSI/ISA-60079-0, ANSI/ISA-60079-11, ANSI/ISA-61241-0

IEC 60079-0 or ANSI/ISA-61241-11 IEC 60079-11, the requirement of this standard takes precedence.

This standard supplements IEC 60079-11, the requirements of which apply to electrical apparatus used in intrinsically safe electrical systems.

The installation requirements of Group II or Group III systems designed in accordance with this standard are specified in the National Electrical Code ANSI/NFPA 70 IEC 60079-14.

NOTE 2 Group I installation requirements are presently not provided in IEC 60079-14.

Description:

Explosive Atmospheres - Part 1: Equipment Protection by Flameproof Enclosures

Notes:

Scope

This part of IEC 60079 document specifies the general requirements for construction, testing and marking of Ex Equipment and Ex Components intended for use in explosive atmospheres.

Explosive atmospheres are identified by the National Electrical Code®, ANSI/NFPA 70 as hazardous (classified) locations and include the following specified locations:

  1. •  Zone 0

  2. •  Zone 1

  3. •  Zone 2

  4. •  Zone 20

  5. •  Zone 21

  6. •  Zone 22

See 1 for the relationship of the Equipment Protection Level (EPL) to the Zone area classification.

The standard atmospheric conditions (relating to the explosion characteristics of the atmosphere) under which it may be assumed that Ex Equipment can be operated are:

• temperature –20 °C to +60 °C;

• pressure 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and

• air with normal oxygen content, typically 21 % v/v.

This part of IEC 60079 document and other standards supplementing this standard specify additional test requirements for Ex Equipment operating outside the standard temperature range, but further additional consideration and additional testing may be required for Ex Equipment operating outside the standard atmospheric pressure range and standard oxygen content. Such additional testing may be particularly relevant with respect to Types of Protection that depend on quenching of a flame such as ‘flameproof enclosures “d”’  (IEC 60079-1) or limitation of energy, ‘intrinsic safety “i”’ (IEC 60079-11).

NOTE 1 Although the standard atmospheric conditions above give a temperature range for the atmosphere of -20 °C to +60 °C, the normal ambient temperature range for the Ex Equipment is –20 °C to +40 °C, unless otherwise specified and marked. See 1. It is considered that –20 °C to +40 °C is appropriate for many items of Ex Equipment and that to manufacture all Ex Equipment to be suitable for a standard atmosphere upper ambient temperature of +60 °C would place unnecessary design constraints.

NOTE 2 Requirements given in this standard result from an ignition hazard assessment made on equipment. The ignition sources taken into account are those found associated with this type of equipment, such as hot surfaces, electromagnetic radiation, mechanically generated sparks, mechanical impacts resulting in thermite reactions, electrical arcing and static electric discharge in normal industrial environments.

NOTE 3 Where an explosive gas atmosphere and a combustible dust atmosphere are, or can be, present at the same time, the simultaneous presence of both often warrants additional protective measures.

Additional guidance on the use of Ex Equipment in hybrid mixtures (mixture of a flammable gas or vapour with a combustible dust or combustible flyings) is given in IEC 60079-14.

DE

IEC 60079

This standard does not specify requirements for safety, other than those directly related to the explosion risk.

Ignition sources like adiabatic compression, shock waves, exothermic chemical reaction, self-ignition of dust, naked flames and hot gases/liquids, are not addressed by this standard.

NOTE 4 Although outside the scope of this standard, such equipment would typically be subjected to a hazard analysis that identifies and lists all of the potential sources of ignition by the equipment and the measures to be applied to prevent them becoming effective. See ISO/IEC 80079-36.

Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use - Part 2-032: Particular Requirements for Hand-Held and Hand-Manipulated Current Sensors for Electrical Test and Measurement

Notes:

Summary of Topics

This new Third Edition of ANSI/UL 61010-2-032 dated October 17, 2024 is an Adoption of IEC 61010-2-032, Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use – Part 2-032: Particular Requirements for Hand-Held and Hand-Manipulated Current Sensors for Electrical Test and Measurement (fifth edition, issued by IEC September 2023) as a new IEC-based UL standard with US National Differences.

Scope and object

This clause of Part 1 is applicable except as follows:

Replace the existing text with the following:

This part of IEC 61010 specifies safety requirements formHAND-HELD and hand-manipulated current sensors described below.

These current sensors are for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of the circuit being measured. They can be stand-alone current sensors or accessories to other equipment or parts of combined equipment (see ). These include measurement circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. These current sensors and circuits need additional protective means between the current sensor, the circuit and an OPERATOR.

NOTE 1 Combined equipment is equipment that is electrically connected to a current sensor by means of a permanent connection which can be detached only by the use of a TOOL.

NOTE 2 Some current sensors are also known as current clamps,

CLAMP MULTIMETERS and current probes.

Current sensors are hand-manipulated before and/or after a test or measurement, but do not necessarily need to be HAND-HELD during the test or measurement. Current sensors used as FIXED EQUIPMENT are not within the scope of this document.

The following types of current sensors are covered:

a) Type A: a current sensor designed to be applied to or removed from HAZARDOUS LIVE UNINSULATED CONDUCTORS. Type A current sensors have defined HAND-HELD or hand-manipulated parts providing protection against electric shock from the conductor being measured, and also have protection against short-circuits between wires and between busbars during clamping.

b) Type B: a current sensor which has protection against short-circuits between wires or busbars during clamping but without defined HAND-HELD or hand-manipulated parts which provide protection against electric shock during clamping. Additional protective means are necessary to avoid electric shock from HAZARDOUS LIVE conductors which cannot be de-energised during application or removal of the current sensor.

EXAMPLE 1 Flexible current sensors.

c) Type C: a current sensor without protection against short-circuits between wires or busbars during clamping. Type C current sensors are intended to be applied to or removed from

HAZARDOUS LIVE UNINSULATED CONDUCTORS or from non-limited-energy circuit conductors only when they are de-energised.

EXAMPLE 2 Split-core transducers.

d) Type D: a current sensor designed to be applied to or removed from insulated conductors or from limited-energy circuit conductors.

EXAMPLE 3 Current probes for oscilloscopes and earth leakage current detectors.

All current sensors can also be used with insulated conductors. In this case, HAZARDS are limited to acceptable levels by the insulation of the conductors.

Additional requirements for CLAMP MULTIMETERS are given in Annex EE. shows graphical representations of typical current sensors for illustration purposes. Current sensors can look different depending on the design.

This clause of Part 1 is applicable, except as follows:

Replacement:

Replace the second paragraph by the following:

This Part 2 of IEC 61010 specifies particular safety requirements for the following types a) to c) of electrical equipment and their accessories, wherever they are intended to be used, whenever that equipment incorporates REFRIGERATING SYSTEMS as an integral part of, or separate from, the equipment and the equipment is in direct control of the REFRIGERATING SYSTEM.

This document details all the requirements when up to 150 g of FLAMMABLE REFRIGERANT are used per stage of a REFRIGERATING SYSTEM. Additional requirements beyond the current scope of this document apply if a REFRIGERANT charge of FLAMMABLE REFRIGERANT exceeds this amount.

For REFRIGERATION SYSTEM with more than 150 g per stage, the requirement of UL 60335-2-89 shall be used. Transcritical REFRIGERATION SYSTEMS and systems that use ammonia (NH3) as the REFRIGERANT shall be evaluated to the requirements of UL 60335-2-89.

Addition:

Add the following text after the last paragraph:

NOTE 101 Examples for REFRIGERATING EQUIPMENT include, but are not limited to, laboratory equipment such as laboratory refrigerators, freezers, refrigerated display cabinets.

It is possible that all or part of the equipment falls within the scope of one or more other Part 2 standards of IEC 61010 as well as within the scope of this standard. In that case, the requirements of those other Part 2 standards will also apply. In particular, if equipment is intended to be used as a centrifuge, the requirements of IEC 61010-2-020 apply. However, when the equipment incorporates a refrigerating system and a heating function where the combination of the two introduces additional or more severe HAZARDS than if treated separately, then it is possible that IEC 61010-2-012 is applicable instead of this Part 2-011.

Description:

Insulation Coordination Including Clearances and Creepage Distances for Electrical Equipment

Notes:

1.1 These requirements cover an alternate approach to specifying through air and over surface spacings for electrical equipment through the use of the principles of insulation coordination.

1.2 The complete principles of insulation coordination involve the consideration of the combination of clearances, creepage distances, and the properties of solid insulation used to constitute the insulation system. The empirical data gathered thus far has been used to develop the requirements for clearances and creepage distances as presented in this standard. The data needed to develop the evaluation procedure for solid insulation is still being gathered. When available, this evaluation procedure will be added to this standard and is not expected to affect the requirements for clearances and creepage distances.

1.3 These requirements may be used as an alternate to required spacing levels specified in end-product standards. The end product standard spacing requirements may be based on use and systems where overvoltages are not controlled, or if controlled, the level of control is unknown.

1.4 These alternate requirements are intended to be applied to a particular product category if the standard covering the product category specifically references UL 840 or any of the requirements therein.

1.5 Users of these requirements may need to specify the overvoltage levels and the methods of control which will be utilized, and establish the pollution degree to which the product insulation system will be expected to be subjected.

1.6 It is not intended that the test values in this standard be employed for production line testing. However, users of these requirements will need to establish a means to ensure that production controls applied to permit the spacing reduction remain in effect during the manufacture of the product. This could include sample testing or physical measurements or another equivalent means.

1.7 Users of these requirements will additionally need to ensure that influencing factors not addressed in this standard, such as mechanical movement, field placement of conductive material, and product damage, will not affect the system for insulation coordination. Examples are the deformation of the enclosure, movement of the fittings for conduit or armored cable, or the improper installation of field wiring. Clearances and creepage distances at those locations must be verified for compliance by physical measurement in accordance with Section 10, Measurement of Clearance and Creepage Distances.

Notes:

1.1 These requirements cover fused power-circuit devices to be employed in accordance with the National Electrical Code.

1.2 Fused power-circuit devices, as covered by these requirements, are considered to be either bolted pressure contact switches or high-pressure butt-type contact switches.

1.3 Bolted-pressure contact switches are devices in which the blade-jaw connections have an additional pressure or clamping action provided at both ends of the switch blades when the blades are in the fully closed position.

1.4 High-pressure butt-type contact switches are devices having butt-type contacts and a spring-charged mechanism.

1.5 These requirements do not apply to low-voltage AC power circuit protectors as covered by the Standard for Low Voltage AC Power Circuit Protectors Used in Enclosures, ANSI/IEEE C37.29, or to low-voltage AC integrally fused power circuit breakers as covered by the Standard for Low-Voltage AC Power Circuit Breakers Used in Enclosures, ANSI/IEEE C37.13.

1.6 Fused power-circuit devices may be manually or electrically operated and may incorporate electrical tripping means.

1.7 An electrically tripped device is one whose closing is performed manually or electrically but contact opening is performed by a release energized by a separate source of voltage.

1.8 A device with an electrical operator is one whose contact closing and opening is performed by electrical means.

1.9 Fused power-circuit devices have continuous current ratings of more than 600 A and voltage ratings of 600 V or less AC, DC, or both. Devices rated AC are intended for use on circuits having maximum available short-circuit currents of 100,000, 150,000, or 200,000 A (rms symmetrical). Devices rated DC are intended for use on circuits having maximum available short-circuit currents of 20,000, 50,000, 100,000, 150,000, or 200,000 A DC.

1.10 Fused power-circuit devices have provisions for mounting (or are intended to be used with upstream) Class L fuses or Class T fuses rated more than 600 A.

1.11 These requirements cover complete, enclosed fused power-circuit devices in which the switch is integral with the enclosure; open-type fused power-circuit devices intended for mounting in other equipment, such as switchboards or in a separately shipped enclosure; and enclosures intended for mounting open-type fused power-circuit devices.

Standard for Special Fuses for Radio- and Television- Type Appliances

Notes:

Scope

1.1 These requirements cover special types of fuses not covered by separate requirements and that are for use in radio- and television-type appliances where they are relied upon to limit power or current, or both. These requirements also apply to holders intended to accept such special fuses, where the holder may be an integral part of the fuse design. It should be noted, however, that compliance of a special fuse with these requirements does not assure that it is acceptable for use as a protective device in the end-use product.

1.2 A special fuse is a single function (providing protection only) device intended to interrupt a current flow when the current passing through it exceeds a preselected value. It is nonrenewable, that is, the fuse element cannot be replaced after operation, but it can be multi-operational (multi-element).

1.3 The acceptability of any special fuse covered by these requirements in any particular device or appliance depends upon its effectiveness in continued use under the conditions that prevail in actual service. Accordingly, for a particular application, the special fuse may be affected by the requirements for the device or appliance in question, and it may be necessary to employ protective devices having features other than, or in addition to, those specified in these requirements.

Description:

Explosive Atmospheres - Part 28: Protection of Equipment and Transmission Systems Using Optical Radiation

Notes:

DR

1.1 This part of IEC 60079 standard specifies the requirements, testing and marking of equipment emitting optical radiation intended for use in explosive atmospheres. It also covers equipment located outside the explosive atmosphere or protected by a Type of Protection listed in IEC UL 60079-0, but which generates optical radiation that is intended to enter an explosive atmosphere. It covers Groups I, II and III, and EPLs Ga, Gb, Gc, Da, Db, Dc, Ma and Mb.

1.2 This standard contains requirements for optical radiation in the wavelength range from 380 nm to 10 µm. It covers the following ignition mechanisms:

• Optical radiation is absorbed by surfaces or particles, causing them to heat up, and under certain circumstances this may allow them to attain a temperature which will ignite a surrounding explosive atmosphere.

• In rare special cases, direct laser induced breakdown of the gas at the focus of a strong beam, producing plasma and a shock wave both eventually acting as ignition source. These processes can be supported by a solid material close to the breakdown point.

NOTE 1 See a) and d) of the introduction.

1.3 This standard does not cover ignition by ultraviolet radiation and by absorption of the radiation in the explosive mixture itself. Explosive absorbers or absorbers that contain their own oxidizer as well as catalytic absorbers are also outside the scope of this standard.

1.4 This standard specifies requirements for equipment intended for use under atmospheric conditions.

1.5 DR Annex DVF outlines the application of this standard for equipment and transmission systems using optical radiation in areas classified using the Division method.

1.6 DR This standard supplements and modifies the general requirements of IEC UL 60079-0. Where a requirement of this standard conflicts with a requirement of IEC UL 60079-0, the requirement of this standard takes precedence.

1.7 DR Where references are made to IEC, IEC/IEEE, ISO, and ISO/IEC standards, the referenced requirements found in these standards shall apply as modified by any applicable US National Differences for that standard (see Clause 2).

1.8 DR This standard applies to:

1) laser equipment; and

2) optical fibre equipemnt; and

3) any other convergent light sources or beams where light is focused in one single point within the hazardous area.

NOTE 2 Some optical elements such as lenses and reflectors are able to convert divergent light into a convergent beam.

NOTE 3 In accordance with 1DV.1.9 DR, where the standard does not apply to equipment and transmission systems using optical radiation and therefore any associated certification does not reference UL 60079-28, the certificate or other supporting documentation may have the following statement, modified appropriately:

“In accordance with Clause 1DV.1.9 DR Item X) from the scope of UL 60079-28, this standard does not apply to the output of the optical radiation source with respect to explosion protection.”

The reference to “Item X)” above is to be replaced by the actual Item number under Clause 1DV.1.9 DR from the scope of UL 60079-28, e.g. “Item 1)”, “Item 2)”, “Item 3a)”, “Item 3b), “Item 4a)”, “Item 4b)”, “Item 4c)”, “Item 4d)”, “Item 4e)”.

This standard applies to optical fibre equipment and optical equipment, including LED and laser equipment, with the exception of the equipment detailed below:

1) Non-array divergent LEDs used for example to show equipment status or backlight function.

2) All luminaires (fixed, portable or transportable), hand lights and caplights; intended to be supplied by mains (with or without galvanic isolation) or powered by batteries:

– with continuous divergent light sources (for all EPLs),

– with LED light sources (for EPL Gc or Dc only).

NOTE 2 Continuous divergent LED light sources for other than EPL Gc or Dc are not excluded from the standard due to the uncertainty of potential ignition concerns regarding high irradiance.

1.8.1 National Difference deleted

1.9 DR This standard does not apply to:

1) laser equipment for EPL Gb or Gc and Db or Dc applications which complies with Class 1 laser product limits in accordance with IEC 60825-1 or laser equipment for EPL Gc and Dc applications which complies with Class I laser product limits in accordance with the US Code of Federal Regulations, 21 CFR Part 1040; or

NOTE 4 The referenced Class 1 or Class I limits are those that involve emission limits below 15 mW measured at a distance from the optical radiation source in accordance with IEC 60825-1 or the US Code of Federal Regulations, 21 CFR Part 1040, respectively, with this measured distance reflected in the Ex application. Class 1 limits are based on normal operating and single fault conditions, as opposed to Class I limits which are only based on normal operating conditions.

2) divergent light sources or beams where light is not focused within the hazardous area; or

3) Single or multiple optical fibre cables not part of optical fibre equipment if the cables:

a) comply with the relevant industrial standards, along with additional protective means, e.g. robust cabling, conduit or raceway (for EPL Gb, Db, Gc or Dc); or

b) comply with the relevant industrial standards (for EPL Gc or Dc).; or

4) Optical radiation sources as defined in 1DV.1.8 DR above where the optical radiation is fully contained in an enclosure complying with one of the followings Types of Protection suitable for the EPL, or the minimum ingress protection rating specified:

a) flameproof "d" enclosures (UL 60079-1); or

NOTE 5 A flameproof “d” enclosure is suitable because an ignition due to optical radiation in combination with absorbers inside the enclosure is contained.

b) pressurized "p" enclosures (UL 60079-2); or

NOTE 6 A pressurized “p” enclosure is suitable because there is protection against ingress of an explosive atmosphere.

c) restricted breathing “nR” enclosure (UL 60079-15); or

NOTE 7 A restricted breathing “nR” enclosure is suitable because there is protection against ingress of an explosive atmosphere.

d) dust protection "t" enclosures" (UL 60079-31); or

NOTE 8 A dust protection “t” enclosure is suitable because there is protection against ingress of an explosive dust atmosphere.

e) an enclosure that provides a minimum ingress protection of IP 6X and where no internal absorbers are to be expected and complying with “Tests of enclosures” in UL 60079-0.

NOTE 9 An enclosure of a minimum ingress protection of IP 6X and complying with “Tests of enclosures” in UL 60079-0 is suitable because there is protection against the ingress of absorbers. It is anticipated that when the enclosures are opened, entrance of any absorbers is avoided.

3) Optical radiation sources for EPL Mb, Gb or Gc and Db or Dc applications which comply with Class 1 limits in accordance with IEC 60825-1.

NOTE 3 The referenced Class 1 limits are those that involve emission limits below 15 mW measured at a distance from the optical radiation source in accordance with IEC 60825-1, with this measured distance reflected in the Ex application.

4) Single or multiple optical fibre cables not part of optical fibre equipment if the cables:

– comply with the relevant industrial standards, along with additional protective means, e.g. robust cabling, conduit or raceway (for EPL Gb, Db, Mb, Gc or Dc),

– comply with the relevant industrial standards (for EPL Gc or Dc).

5) Enclosed equipment involving an enclosure that fully contains the optical radiation and that complies with a suitable type of protection as required by the involved EPL, with the enclosure complying with one of the following conditions:

– An enclosure for which an ignition due to optical radiation in combination with absorbers inside the enclosure would be acceptable such as flameproof "d" enclosures (IEC 60079-1), or

– An enclosure for which protection regarding ingress of an explosive gas atmosphere is provided, such as pressurized "p" enclosures (IEC 60079-2), restricted breathing “nR” enclosure (IEC 60079-15), or

– An enclosure for which protection regarding ingress of an explosive dust atmosphere is provided, such as dust protection "t" enclosures" (IEC 60079-31), or

– An enclosure for which protection regarding ingress of absorbers is provided (such as IP 6X enclosures) and where no internal absorbers are to be expected.

NOTE 4 For these scope exclusions based on enclosure constructions, it is anticipated that the enclosures are not opened in the explosive atmosphere, so that ingress is protected.

1 Scope

The scope of IEC 61730-1 is also applicable to this part of IEC 61730. While IEC 61730-1 outlines the requirements of construction, this part of the standard lists the tests a PV module is required to fulfill for safety qualification. IEC 61730-2 is applied for safety qualification only in conjunction with IEC 61730-1.

The sequence of tests required in this standard may not test for all possible safety aspects associated with the use of PV modules in all possible applications. This standard utilizes the best sequence of tests available at the time of its writing. There are some issues – such as the potential danger of electric shock posed by a broken PV module in a high voltage system – that should be addressed by the system design, location, restrictions on access and maintenance procedures.

The objective of this standard is to provide the testing sequence intended to verify the safety of PV modules whose construction has been assessed by IEC 61730-1. The test sequence and pass criteria are designed to detect the potential breakdown of internal and external components of PV modules that would result in fire, electric shock, and/or personal injury. The standard defines the basic safety test requirements and additional tests that are a function of the PV module end-use applications. Test categories include general inspection, electrical shock hazard, fire hazard, mechanical stress, and environmental stress.

The additional testing requirements outlined in relevant ISO standards, or the national or local codes which govern the installation and use of these PV modules in their intended locations, should be considered in addition to the requirements contained within this standard.

Scope

This part of IEC 61730 specifies and describes the fundamental construction requirements for photovoltaic (PV) modules in order to provide safe electrical and mechanical operation. Specific topics are provided to assess the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. This part of IEC 61730 pertains to the particular requirements of construction. IEC 61730-2 defines the requirements for testing.

This International Standard series lays down IEC requirements of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. This standard is intended to apply to all terrestrial flat plate module materials such as crystalline silicon module types as well as thin-film modules.

PV modules covered by this standard are limited to a maximum DC system voltage of 1 500 V.

This International Standard defines the basic requirements for various applications of PV modules, but it cannot be considered to encompass all national or regional codes. Specific requirements, e.g. for building, marine and vehicle applications, are not covered.

This International Standard does not address specific requirements for products that combine a PV module with power conversion equipment, monitoring or control electronics, such as integrated inverters, converters or output disabling functions.

While parts of this standard may be applicable to flat plate PV modules with internally generated low level concentration below 3 times, it was not written specifically to address these concerns.

This International Standard is designed to coordinate with the test sequences in the IEC 61215 series, so that a single set of samples may be used to perform both the safety and qualification of a photovoltaic module design.

The object of this International Standard is to define the requirements for the construction of photovoltaic modules with respect to safety. These requirements are intended to minimize the misapplication and misuse of PV modules or the failure of their components which could result in fire, electric shock and personal injury.

Additional construction requirements outlined in relevant ISO standards, or the national or local codes which govern the installation and use of these PV modules in their intended locations, should be considered in addition to the requirements contained within this standard.

Photovoltaic System Performance - Part 3: Energy Evaluation Method

Notes:

Summary of Topics

This revision of ANSI/UL 61724-3 dated June 27, 2023 is being issued to update the title page to reflect the most recent designation as a Reaffirmed American National Standard (ANS). No technical changes have been made.

UL 61724-3 is an adoption of IEC 61724-3, Technical Specification for Photovoltaic system performance – Part 3: Energy evaluation method (First Edition, issued by the IEC July 2016). Please note that the National Difference document incorporates all of the U.S. national differences for UL 61724-3.

Scope

This part of IEC 61724, which is a Technical Specification, defines a procedure for measuring and analyzing the energy production of a specific photovoltaic system relative to expected electrical energy production for the same system from actual weather conditions as defined by the stakeholders of the test. The method for predicting the electrical energy production is outside of the scope of this technical specification. The energy production is characterized specifically for times when the system is operating (available); times when the system is not operating (unavailable) are quantified as part of an availability metric.

For best results, this procedure should be used for long-term performance (electrical energy production) testing of photovoltaic systems to evaluate sustained performance of the system over the entire range of operating conditions encountered through the duration of the test (preferably one year). Such an evaluation provides evidence that long-term expectations of system energy production are accurate and covers all environmental effects at the site. In addition, for the year, unavailability of the system (because of either internal or external causes) is quantified, enabling a full assessment of electricity production.

In this procedure, inverter operation and other status indicators of the system are first analyzed to find out whether the system is operating. Times when inverters (or other components) are not operating are characterized as times of unavailability and the associated energy loss is quantified according to the expected energy production during those times. For times when the system is operating, actual photovoltaic system energy produced is measured and compared to the expected energy production for the observed environmental conditions, quantifying the energy performance index, as defined in IEC 61724-1. As a basis for this evaluation, expectations of energy production are developed using a model of the PV system under test that will serve as the guarantee or basis for the evaluation and is agreed upon by all stakeholders of the project. Typically, the model is complex and includes effects of shading and variable efficiency of the array, but the model can also be as simple as a performance ratio, which may be more commonly used for small systems, such as residential systems.

The procedure evaluates the quality of the PV system performance, reflecting both the quality of the initial installation and the quality of the ongoing maintenance and operation of the plant, with the assumption and expectation that the model used to predict performance accurately describes the system performance. If the initial model is found to be inaccurate, the design of the system is changed, or it is desired to test the accuracy of an unknown model, the model may be revised relative to one that was applied earlier, but the model should be fixed throughout the completion of this procedure.

The aim of this technical specification is to define a procedure for comparing the measured electrical energy with the expected electrical energy of the PV system. The framework procedure focuses on items such as test duration, data filtering methods, data acquisition, and sensor choice. To reiterate, the procedure does not proscribe a method for generating predictions of expected electrical energy. The prediction method and assumptions used are left to the user of the test. The end result is documentation of how the PV system performed relative to the energy performance predicted by the chosen model for the measured weather; this ratio is defined as the performance index in IEC 61724-1.

This test procedure is intended for application to grid-connected photovoltaic systems that include at least one inverter and the associated hardware.

This procedure is not specifically written for application to concentrator (> 3X) photovoltaic (CPV) systems, but may be applied to CPV systems by using direct-normal irradiance instead of global irradiance.

This test procedure was created with a primary goal of facilitating the documentation of a performance guarantee, but may also be used to verify accuracy of a model, track performance (e.g., degradation) of a system over the course of multiple years, or to document system quality for any other purpose. The terminology has not been generalized to apply to all of these situations, but the user is encouraged to apply this methodology whenever the goal is to verify system performance relative to modeled performance. Specific guidance is given for providing the metrics requested for the IECRE certification process, providing a consistent way for system performance to be documented.

Photovoltaic system performance - Part 2: Capacity evaluation method

Summary of Topics

This revision of ANSI/UL 61724-2 dated June 27, 2023 is being issued to update the title page to reflect the most recent designation as a Reaffirmed American National Standard (ANS). No technical changes have been made.

UL 61724-2 is an adoption of IEC 61724-2, Technical Specification for Photovoltaic system performance – Part 2: Capacity evaluation method (First Edition, issued by the IEC October 2016), with no US National Differences.

Scope

This part of IEC 61724 defines a procedure for measuring and analyzing the power production of a specific photovoltaic system with the goal of evaluating the quality of the PV system performance. The test is intended to be applied during a relatively short time period (a few relatively sunny days).

In this procedure, actual photovoltaic system power produced is measured and compared to the power expected for the observed weather based on the design parameters of the system. The expected power under reference and measured conditions are typically derived from the design parameters that were used to derive the performance target for the plant as agreed to prior to the commencement of the test. For cases when a power model was not developed during the plant design, a simple model that increases transparency is presented in the annexes as a possible approach.

The intent of this document is to specify a framework procedure for comparing the measured power produced against the expected power from a PV system on relatively sunny days. This test procedure is intended for application to grid-connected photovoltaic systems that include at least one inverter and the associated hardware.

The performance of the system is quantified both during times when the inverters are maximum-power-point tracking and during times when the system power is limited by the output capability of the inverter or interconnection limit, reducing the system output relative to what it would have been with an inverter with generation freely following irradiance, if this condition is relevant.

This procedure can be applied to any PV system, including concentrator photovoltaic systems, using the irradiance (direct or global) that is relevant to the performance of the system.

This test procedure was designed and drafted with a primary goal of facilitating the documentation of a performance target, but it can also be used to verify a model, track performance (e.g., degradation) of a system over the course of multiple years, or to document system quality for any other purpose. The terminology has not been generalized to apply to all of these situations, but the intent is to create a methodology that can be used whenever the goal is to verify system performance at a specific reference condition chosen to be a frequently observed condition. A more complete evaluation of plant performance can be accomplished by using the complementary Technical Specification IEC TS 61724-3 Photovoltaic system performance – Part 3: Energy evaluation method.

Photovoltaic Systems - Design Qualification of Solar Trackers

Notes:

Summary of Topics

This is the First Edition of the UL IEC-Based ANSI/UL 62817, Standard for Photovoltaic Systems – Design Qualification of Solar Trackers, dated September 22, 2023.

UL 62817 is an adoption of IEC 62817 edition 1.1 which contains the first edition (2014-08) and its amendment 1 (2017-07), with no US National Differences.

Scope and object

This International Standard is a design qualification standard applicable to solar trackers for photovoltaic systems, but may be used for trackers in other solar applications. The standard defines test procedures for both key components and for the complete tracker system. In some cases, test procedures describe methods to measure and/or calculate parameters to be reported in the defined tracker specification sheet. In other cases, the test procedure results in a pass/fail criterion.

The objective of this design qualification standard is twofold.

First, this standard ensures the user of the said tracker that parameters reported in the specification sheet were measured by consistent and accepted industry procedures. This provides customers with a sound basis for comparing and selecting a tracker appropriate to their specific needs. This standard provides industry-wide definitions and parameters for solar trackers. Each vendor can design, build, and specify the functionality and accuracy with uniform definition. This allows consistency in specifying the requirements for purchasing, comparing the products from different vendors, and verifying the quality of the products.

Second, the tests with pass/fail criteria are engineered with the purpose of separating tracker designs that are likely to have early failures from those designs that are sound and suitable for use as specified by the manufacturer. Mechanical and environmental testing in this standard is designed to gauge the tracker’s ability to perform under varying operating conditions, as well as to survive extreme conditions. Mechanical testing is not intended to certify structural and foundational designs, because this type of certification is specific to local jurisdictions, soil types, and other local requirements.

Photovoltaic System Power Conversion Equipment - Design Qualification and Type Approval

Notes:

Summary of Topics

This Second Edition ANSI/UL 62093 dated December 7, 2023 is an adoption of IEC 62093, Photovoltaic System Power Conversion Equipment – Design Qualification and Type Approval (Second Edition, issued January 2022) with US National Differences.

Scope

This document lays down IEC requirements for the design qualification of power conversion equipment (PCE) suitable for long-term operation in terrestrial photovoltaic (PV) systems.

This document covers electronic power conversion equipment intended for use in terrestrial PV applications. The term PCE refers to equipment and components for electronic power conversion of electric power into another kind of electric power with respect to voltage, current, and frequency. This document is suitable for PCE for use in both indoor and outdoor climates as defined in IEC 60721-3-3 and IEC 60721-3-4. Such equipment may include, but is not limited to, grid-tied and off-grid DC-to-AC PCEs, DC-to-DC converters, battery charger converters, and battery charge controllers.

This document covers PCE that is connected to PV arrays that do not nominally exceed a maximum circuit voltage of 1 500 V DC. The equipment may also be connected to systems not exceeding 1 000 V AC at the AC mains circuits, non-main AC load circuits, and to other DC source or load circuits such as batteries. If particular ancillary parts whereby manufacturers and models are specified in the manual for use with the PCE, then those parts are tested with the PCE.

Exceptions:

a) This document does not address characteristics of power sources other than PV systems, such as wind turbines, fuel cells, rotating machine sources, etc.

b) This document does not address the characteristics of power electronic conversion equipment fully integrated into photovoltaic modules. Separate standards exist or are in development for those types of devices. It is, however, applicable to devices where the manufacturer explicitly specifies the capability of full detachment from and subsequent reattachment to the PV module or if the input and output terminals can be accessed and a specification sheet for the PCE is available. Devices meeting these requirements may be tested as individual samples independent from the PV module.

c) This document does not apply to power conversion equipment with integrated (built-in) electrochemical energy storage (e.g. lead acid or lithium-ion). It is, however, applicable to equipment where the manufacturer specifies and permits complete removal of the electrochemical energy storage from the PCE so that stand-alone assessment of the PCE with the storage removed becomes possible.

The object of the test sequences contained herein is to establish a basic level of durability and to show, as far as it is possible within reasonable constraints of cost and time, that the PCE is capable of maintaining its performance after prolonged exposure to the simulated environmental stresses described herein that are based on the intended use conditions specified by the manufacturer. Optional tests contained herein may be selected depending on the intended installation, market, or special environmental conditions that the PCE is anticipated to experience. The categorization imposes differentiated test sequences and test severity levels reflecting the different requirements of mechanical and electrical components in different environments.

PCEs are grouped into categories based on size and installation environment.

The actual life expectancy of components so qualified depends on their design, their environment, and the conditions under which they are operated. Estimation of a lifetime and wear out is not generally covered by this document.

This document is intended to be independent of safety standards such as UL 1741 and UL 62109-1. It is intended to be used in conjunction with those safety standards and should not replace them.

Photovoltaic (PV) Luminaire Systems

Notes:

Scope

1.1 These requirements apply to low voltage luminaire systems whose electrical power is derived from photovoltaic modules. They include, at a minimum, a photovoltaic (PV) module, storage batteries, one or more co-located luminaires, and controls to manage the energy flow between these subassemblies. They are intended to be installed in accordance with 1) the CE Code, CSA C22.1-18, Section 64 (Renewable Energy Systems) and 2) NFPA 70, the National Electrical Code (NEC), Article 710 as a stand-alone system.

Informational Note: Per CE Code 64-000 Scope (1), renewable energy systems operating within the class 2 limits of 16-200(1)(a) and (1)(b) are exempt from the requirements of Section 64.

1.2 These requirements do not address 1) the grid-interactive systems covered by CE Code Section 64 and NEC Article 705, 2) systems that include an inverter intended to supply line voltage luminaires or remote equipment, or 3) individual system subassemblies (PV modules, batteries, luminaires, or controls) that have not been evaluated as a PV luminaire system.

1.3 These PV luminaire systems can include means to connect to and receive energy from the utility grid or similar supplemental supply source; see Annex A, Systems with Supplementary Power Connections. Systems with this feature have additionally been evaluated for conformance to the relevant aspects of NEC Article 702, Optional Standby Systems.

1.4 These requirements apply to fixed-in-place assemblies, to portable assemblies that are intended to be easily relocated, and to assemblies intended for periodic user disassembly and storage. These requirements do not apply to handheld luminaires, such as a flashlight, or where light output is an auxiliary function of the handheld device (such as a smart phone).

1.5 These assemblies are intended for outdoor, exposed installations within a nominal ambient temperature range as marked per clause 3, but no less than -20 C to +40 C.

1.6 These systems may include controls and devices to optimize system performance (such as sensors, positioning motors, and communication devices). They may also include output ports for diagnostic purposes or to supply temporary power to portable devices. See Annex B.

1.7 These requirements address some of the mechanical infrastructure used to support or mount parts of the system. However, these requirements address only those features of these mechanical systems relative to risks of electric shock, fire, injury, and property damage. The supplemental requirements to fully evaluate the structural integrity of the mechanical infrastructure, including strength and stability of support poles under various environmental conditions such as wind or impact, and the assessment of soil or ground conditions necessary for system physical stability and reliability, are outside the scope of this document.

1.8 Except for components intended to connect to the utility for supplemental power in accordance with Annex A, these systems are expected to operate below 30 Vdc, the outdoor (wet location) class 2 voltage limits of CE Code Section 16-222(3)(b) and the National Electrical Code (NEC). As permitted by CE Code 13-1202(3) (Extra-Low Voltage Lighting Systems) and NEC 411, these systems do not require grounding other than where required by Annex A. All systems are permitted to use earth ground as a reference. Any system components carrying higher voltages will require supplemental safeguards (for example, grounding or double insulation) not fully addressed within these requirements.

1.9 These requirements do not consider the vibration and other environmental conditions that may occur for systems installed on watercraft, recreational vehicles, or other mobile platforms.

1.10 These requirements do not address the required performance for certain life safety-related applications, such as for emergency signaling or emergency/egress lighting. Additional requirements from those application-specific standards should be applied to ensure the required performance expectations can be achieved. These requirements also do not address any additional considerations that may be applicable to installation in Classified (Hazardous) Locations.

Summary of Topics

This First Edition of ANSI/CAN/UL 3741, Standard for Photovoltaic Hazard Control, has been issued to reflect the latest ANSI and SCC approval dates, and to incorporate the proposals dated March 6, 2020 and September 18, 2020.

Scope

1 1.1 Fire fighters (FF) performing operations involving buildings with attached or integrated Photovoltaic (PV) arrays may be exposed to electrical hazards from damaged PV equipment. These requirements provide a means for evaluation of PV Hazard Control components, equipment and systems that provide a reduced level of shock hazard from energized PV system equipment and circuits located within the PV array after the operation of hazard control initiation function(s) where required, such as but not limited to any PV Rapid Shutdown Equipment (PVRSE) or PV Rapid Shutdown Systems (PVRSS) that comply with UL 1741 in the United States and CSA C22.2 No 330 in Canada.

NOTE: Damaged PV equipment in arrays includes damage as a result of fire fighter (FF) interaction as identified throughout this standard and also common PV faults such as PV array ground faults.

1 1.2 This standard is based on the presupposition that the PV array is installed by qualified persons in accordance with the installation instructions and all applicable installation codes and standards. Evaluation to this standard should not replace other requirements addressing the control of power source(s) for the purposes of worker safety during installation or maintenance. Energized circuits can remain in some PV array equipment after any required hazard control initiation function is operated.

NOTE: Requirements for PV arrays addressed in this standard are intended for compliance with the National Electrical Code (NEC), NFPA 70, 2017 and 2020 editions and their requirements for controlling electrical shock hazards inside the array boundary as addressed in NEC section 690.12(B)(2), Rapid Shutdown of PV Systems on Buildings and with the Canadian Electrical Code (CE Code) C22.1. A PVHCS may or may not additionally comply with the 30V in 30 seconds requirements outside the PV array as required in 690.12 (B)(1).

1 1.3 This standard evaluates the hazards associated with potential exposure to DC currents through defined fire fighter (FF) interactions. Alternating current (AC) exposure is limited to not more than 15 Vac, 8A and 240VA for any circuit within the array boundary.

NOTE: This ac voltage limit is aligned with the PVRS requirements in UL 1741 and general electric shock limits.

Insulation Coordination Including Clearances and Creepage Distances for Electrical Equipment

Notes:

1.1 These requirements cover an alternate approach to specifying through air and over surface spacings for electrical equipment through the use of the principles of insulation coordination.

1.2 The complete principles of insulation coordination involve the consideration of the combination of clearances, creepage distances, and the properties of solid insulation used to constitute the insulation system. The empirical data gathered thus far has been used to develop the requirements for clearances and creepage distances as presented in this standard. The data needed to develop the evaluation procedure for solid insulation is still being gathered. When available, this evaluation procedure will be added to this standard and is not expected to affect the requirements for clearances and creepage distances.

1.3 These requirements may be used as an alternate to required spacing levels specified in end-product standards. The end product standard spacing requirements may be based on use and systems where overvoltages are not controlled, or if controlled, the level of control is unknown.

1.4 These alternate requirements are intended to be applied to a particular product category if the standard covering the product category specifically references UL 840 or any of the requirements therein.

1.5 Users of these requirements may need to specify the overvoltage levels and the methods of control which will be utilized, and establish the pollution degree to which the product insulation system will be expected to be subjected.

1.6 It is not intended that the test values in this standard be employed for production line testing. However, users of these requirements will need to establish a means to ensure that production controls applied to permit the spacing reduction remain in effect during the manufacture of the product. This could include sample testing or physical measurements or another equivalent means.

1.7 Users of these requirements will additionally need to ensure that influencing factors not addressed in this standard, such as mechanical movement, field placement of conductive material, and product damage, will not affect the system for insulation coordination. Examples are the deformation of the enclosure, movement of the fittings for conduit or armored cable, or the improper installation of field wiring. Clearances and creepage distances at those locations must be verified for compliance by physical measurement in accordance with Section 10, Measurement of Clearance and Creepage Distances.

Low-Voltage Switchgear and Controlgear - Part 4-1: Contactors and Motor-Starters - Electromechanical Contactors and Motor-Starters

Notes:

Scope

This part of IEC 60947 applies to the types of equipment listed in 1 and 2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.

Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 4) forms part of the installation but not necessarily of the contactor or the starter.

In this context, this standard gives requirements for:

– contactors associated with overload and/or short-circuit protective devices;

– starters associated with separate short-circuit protective devices and/or with separate short-circuit and integrated overload protective devices;

– contactors or starters combined, under specified conditions, with their own short-circuit protective devices. Such combinations, e.g. combination starters or protected starters are rated as units.

For circuit-breakers and fuse-combination units used as short-circuit protective devices in combination starters and in protected starters, the requirements of IEC 60947-2 and IEC 60947-3 respectively apply.

Equipment covered by this standard is as follows.

This equipment is intended for installation in accordance with CSA C22.1, Canadian Electrical Code (CE Code, Part I), and the US National Electrical Code (NEC), NFPA 70.

AC and DC contactors intended for closing and opening electric circuits and, if combined with suitable relays (see 2), for protecting these circuits against operating overloads which may occur therein.

NOTE For contactors combined with suitable relays and which are intended to provide short-circuit protection, the relevant conditions specified for circuit-breakers (IEC 60947-2) additionally apply.

This standard applies also to the actuators of contactor relays and to the contacts dedicated exclusively to the coil circuit of a contactor.

Contactors or starters with an electronically controlled electromagnet are also covered by this standard.

This standard also applies to manual controllers and combination motor controllers. See Annex DVC for specific requirements.

This standard applies to a.c. semiconductor motor controllers and starters, which may include a series mechanical switching device, intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c.

This standard characterizes a.c. semiconductor motor controllers and starters with and without bypass means.

AC semiconductor motor controllers and starters dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (see 4) should form part of the installation, but not necessarily of the a.c. semiconductor motor controller or starter.

In this context, this standard gives requirements for a.c. semiconductor motor controllers and starters associated with separate short-circuit protective devices.

This standard does not apply to

– continuous operation of a.c. motors at motor speeds other than the normal speed;

– semiconductor equipment, including semiconductor contactors (see 2.2.13 of IEC 60947-1:2007) controlling non-motor loads;

– electronic a.c. power controllers covered by IEC 60146 series.

Contactors, overload relays and control circuit devices used in a.c. semiconductor motor controllers and starters should comply with the requirements of their relevant product standard. Where mechanical switching devices are used, they should meet the requirements of their own IEC product standard, and the additional requirements of this standard.

The object of this standard is to state as follows:

– the characteristics of a.c. semiconductor motor controllers and starters and associated equipment;

– the conditions with which a.c. semiconductor motor controllers and starters comply with reference to

a) their operation and behaviour;

b) their dielectric properties;

c) the degrees of protection provided by their enclosures where applicable;

d) their construction;

– the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests;

– the information to be given with the equipment, or in the manufacturer's literature.

NOTE For the purpose of this standard, the term "controller" may be used instead of "a.c. semiconductor motor controller".

1.1 This equipment is intended for installation in accordance with CSA C22.1, Canadian Electrical Code (CE Code, Part I), and the US National Electrical Code (NEC), NFPA 70.

Standard for Programmable Controllers - Part 2: Equipment Requirements and Tests

Notes:

Scope and object

This Part of IEC 61131 specifies requirements and related tests for programmable controllers (PLC) and their associated peripherals (for example, programming and debugging tools (PADTs), human-machine interfaces (HMIs), etc.) which have as their intended use the control and command of machines and industrial processes.

PLCs and their associated peripherals are intended to be used in an industrial environment and may be provided as open or enclosed equipment. If a PLC or its associated peripherals are intended for use in other environments, then the specific requirements, standards and installation practices for those other environments must be additionally applied to the PLC and its associated peripherals.

This standard also applies to any products performing the function of PLCs and/or their associated peripherals.

Equipment covered in this standard is intended for use in overvoltage category II (IEC 60664-1) in low-voltage installations, where the rated mains supply voltage does not exceed a.c. 1 000 V r.m.s. (50/60 Hz), or d.c. 1 500 V. (If PLCs or their associated peripherals are applied in overvoltage category III installations, then additional analysis will be required to determine the suitability of the equipment for those applications.)

1.1DV Modification to Paragraph 4 of 1.1:

Equipment operating at more than 600 V is considered as high voltage equipment with respect to the requirements in the National Electrical Code.

This standard does not deal with the functional safety or other aspects of the overall automated system. PLCs, their application programme and their associated peripherals are considered as components of a control system.

Since PLCs are component devices, safety considerations for the overall automated system including installation and application are beyond the scope of this standard. However, PLC safety as related to electric shock and fire hazards, electrical interference immunity and error detecting of the PLC-system operation (such as the use of parity checking, self-testing diagnostics, etc.), are addressed. Refer to IEC 60364 or applicable national/local regulations for electrical installation and guidelines.

The object of this standard is

- to establish the definitions and identify the principal characteristics relevant to the selection and application of PLCs and their associated peripherals;

- to specify the minimum requirements for functional, electrical, mechanical, environmental and construction characteristics, service conditions, safety, EMC, user programming and tests applicable to PLCs and the associated peripherals.

This Part also specifies

a)    service, storage and transportation requirements for PLCs and their associated peripherals (Clause 4);

b)    functional requirements for PLCs and their associated peripherals (Clause 5);

c)    EMC requirements for PLCs and their associated peripherals (Clause 8);

d)    safety requirements for PLCs and their associated peripherals (Clause 11);

e)    information that the manufacturer is required to supply (Clauses 7, 10 and 14);

f)    test methods and procedures that are to be used for the verification of compliance of PLCs and their associated peripherals with the requirements (Clauses 6, 9, and 12).

The tests are type tests or production routine tests, and not tests related to the ways PLC systems are applied.

1.101DV Addition of the following to 1.1:

This equipment is intended for installation in accordance with the National Electrical Code (NEC) for use in ordinary locations. Requirements based on the NEC are found in Annex dva of this document.

Tests for Flammability of Plastic Materials for Parts in Devices and Appliances

Notes:

1.1 These requirements cover tests for flammability of polymeric materials used for parts in devices and appliances. They are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application.

1.2 The methods described in this Standard involve standard size specimens and are intended to be used solely to measure and describe the flammability properties of materials, used in devices and appliances, in response to a small open flame or radiant heat source under controlled laboratory conditions.

1.3 The tests in the Standard for Tests for Flammability of Small Polymeric Component Materials should be used to evaluate small components which contain materials that can not be fabricated into standardized specimens in the minimum use thickness and subjected to applicable preselection tests in UL 94. Test procedures in UL 1694 are applicable to small components with an overall volume of less than 2500 mm3 (0.15 in3). UL 1694 is generally not applicable to small components with an overall volume greater than 2500 mm3 (0.15 in3).

1.4 The final acceptance of the material is dependent upon its use in complete equipment that conforms with the standards applicable to such equipment. The flammability classification required of a material is dependent upon the equipment or device involved and the particular use of the material. The performance level of a material determined by these methods shall not be assumed to correlate with its performance in end-use application. The actual response to heat and flame of materials depends upon the size and form, and also on the end-use of the product using the material. Assessment of other important characteristics in the end-use application includes, but is not limited to, factors such as ease of ignition, burning rate, flame spread, fuel contribution, intensity of burning, and products of combustion.

1.5 If found to be appropriate, the requirements are applied to other nonmetallic materials.

1.6 These tests, with the exception of the Radiant Panel Test in Section 10, are not applicable to the evaluation of parts where the thickness exceeds 13.0 mm or where the surface area exceeds 1 m2. These requirements do not cover polymeric materials when used for building construction, finishing, or contents such as wall and floor coverings, furnishings, decorative objects and so forth. In addition, the fire resistance (in terms of an hourly rating), flame spread, smoke characterization, and heat release rate is not evaluated. Other fire tests exist and shall be used to evaluate the flammability of materials in the intended end-use-product configuration.

Tests for Flammability of Plastic Materials for Parts in Devices and Appliances

Notes:

Summary of Topics

This new edition of ANSI/UL 94 dated February 28, 2023 includes the removal of corner radius requirement for the plate specimen in 9.3.2, and also incorporates editorial changes including renumbering and reformatting to align with current style.

Scope

1.1 These requirements cover tests for flammability of polymeric materials used for parts in devices and appliances. They are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application.

1.2 The methods described in this Standard involve standard size specimens and are intended to be used solely to measure and describe the flammability properties of materials, used in devices and appliances, in response to a small open flame or radiant heat source under controlled laboratory conditions.

1.3 The tests in the Standard for Tests for Flammability of Small Polymeric Component Materials, UL 1694, should be used to evaluate small components which contain materials that can not be fabricated into standardized specimens in the minimum use thickness and subjected to applicable preselection tests in UL 94. Test procedures in UL 1694 are applicable to small components with an overall volume of less than 2500 mm3 (0.15 in3). UL 1694 is generally not applicable to small components with an overall volume greater than 2500 mm3 (0.15 in3).

1.4 The final acceptance of the material is dependent upon its use in complete equipment that conforms with the standards applicable to such equipment. The flammability classification required of a material is dependent upon the equipment or device involved and the particular use of the material. The performance level of a material determined by these methods shall not be assumed to correlate with its performance in end-use application. The actual response to heat and flame of materials depends upon the size and form, and also on the end-use of the product using the material. Assessment of other important characteristics in the end-use application includes, but is not limited to, factors such as ease of ignition, burning rate, flame spread, fuel contribution, intensity of burning, and products of combustion.

1.5 If found to be appropriate, the requirements are applied to other nonmetallic materials.

1.6 These tests, with the exception of the Radiant Panel Flame Spread Test, Section 10, are not applicable to the evaluation of parts where the thickness exceeds 13.0 mm or where the surface area exceeds 1 m2. These requirements do not cover polymeric materials when used for building construction, finishing, or contents such as wall and floor coverings, furnishings, decorative objects and so forth. In addition, the fire resistance (in terms of an hourly rating), flame spread, smoke characterization, and heat release rate is not evaluated. Other fire tests exist and shall be used to evaluate the flammability of materials in the intended end-use-product configuration.

Fire Tests of Penetration Firestops

Notes:

Scope

1.1 These requirements cover through penetration firestops of various materials and construction that are intended for use in openings in fire resistive wall, floor or floor-ceiling assemblies, and membrane type penetration firestops of various materials and construction that are intended for use in openings in fire resistive wall assemblies.

1.2 The method of testing penetration firestops as specified by these requirements consists of exposure of test samples to a fire of standard time and temperature and to an application of a hose stream. Ratings are then established on the basis of:

a) The length of time the firestop resists fire before the first development of through openings or flaming on the unexposed surface;

b) Acceptable limitation of thermal transmission; and

c) Acceptable performance under the application of the hose stream.

1.3 The method of testing also includes optional air leakage tests to determine the rate of air leakage through penetration firestop systems resulting from a specified air pressure difference applied across the surface of the systems.

1.4 The method of testing also includes optional water leakage tests to determine the ability of penetration firestop systems to resist the passage of water under a three foot pressure head. This method does not evaluate the ability of uncured firestop systems to resist such exposure.

1.5 Two ratings are established for each penetration firestop system: an F rating based upon flame occurrence on the unexposed side of the test sample and acceptable hose stream performance; and a T rating based on temperature rise and flame occurrence on the unexposed side of the test sample and acceptable hose stream performance.

1.6 An L rating may also be established for a penetration firestop system. The L rating is based on the amount of air leakage through the test sample.

1.7 A W rating may also be established for a penetration firestop system. The W rating is based on the water resistance of the test sample.

1.8 The method of testing penetration firestop systems containing piping systems for vented (drain, waste or vent) systems and closed (process or supply) systems is differentiated by the capping or non-capping of the piping systems on the unexposed side of the test assembly as described in 2.

1.9 Tests conducted in accordance with these requirements are intended to demonstrate the performance of penetration firestops during exposure to fire, but are not intended to determine acceptability of firestops for use after exposure to fire. These requirements do not cover the ampacity of conductors encased in penetration firestop materials.

1.10 The results obtained from the air leakage tests are expressed in ft3/min (m3/s) per ft2 (m2) of opening. The results are intended to develop data to assist authorities having jurisdiction, and others, in determining the acceptability of penetration firestops with reference to the control of air movement through the assembly.

1.11 These requirements do not cover outlet boxes and fittings for use in and evaluated for fire resistance as part of a fire-resistance-rated floor, floor-ceiling or wall assembly.

In a multiple-conductor cable that is other than submersible-pump cable and does not have a grounding conductor it is appropriate to have one circuit conductor without insulation. It is also appropriate for a submersible pump cable to have a grounding conductor and for Type USE and USE-2 cables to have an insulated grounding conductor. Each insulated conductor in these cables is rated for 600 V. Type USE cable has thermoset insulation, except for the HDPE portion of HDPE-over-XL insulation where used for single-conductor Type USE cable. Type SE cable has thermoset or thermoplastic insulation.

1.2 These cables have insulation of solid, extruded dielectric material(s) that are for use in wet locations at 75°C (167°F) and lower temperatures. Cables that are marked with a conductor type that includes the letters "HH" have insulation that is for use in dry locations at temperatures as high as 90°C (194°F) as well as in wet locations at 75°C (167°F) and lower temperatures. Cables that are marked with a conductor type that includes "-2" have insulation that is for use in wet or dry locations at temperatures as high as 90°C (194°F).

1.3 Cables containing any conductor that is of a metal other than copper are marked to identify the metal as aluminum or copper-clad aluminum. Aluminum single-rated (see 1.4) Type USE or USE-2 cables containing other than solid 12, 10 or 8 AWG conductor(s) are of an EC-1350 grade aluminum alloy or a registered AA-8000 series electrical-conductor-grade aluminum alloy. In all other cables, the aluminum conductor(s) are of a registered AA-8000 electrical-conductor-grade alloy only.

1.4 "Single-rated" Type USE cable is single-conductor, jacketed or coverless multiple-conductor, and submersible-pump cable without any indication of the conductor type letters on type cable, on the individual conductor(s), or on the tag, reel, or carton. "USE" is the only type designation associated with the cable. See 40.4.

1.5 Type SE cables that are not marked with conductor type letters or are marked with conductor type letters alone ("XHHW", "RHW", or "RHH OR RHW" not followed by "cdrs" or the like) have insulated conductors that do not comply with the Thermoset-Insulated Wires and Cables, UL 44, horizontal flame test. Type SE cables that are marked for use in cable trays comply with a 70,000 Btu/h (20.5 kW) vertical-tray flame test as described in Sections 4 – 11 of the Standard for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685 or the FT4/IEEE 1202 flame test as described in Sections 12 – 19 of UL 1685.

These cables are for the service-entrance and other (NEC) uses described in 4 – 8. In a multiple-conductor cable that is other than submersible-pump cable and does not have a grounding conductor it is appropriate to have one circuit conductor without insulation. It is also appropriate for a submersible pump cable to have a grounding conductor and for Type USE and USE-2 cables to have an insulated grounding conductor. Each insulated conductor in these cables is rated for 600 V. Type USE cable has thermoset insulation, except for the HDPE portion of HDPE-over-XL insulation where used for single-conductor Type USE cable. Type SE cable has thermoset or thermoplastic insulation.

1.2 These cables have insulation of solid, extruded dielectric material(s) that are for use in wet locations at 75°C (167°F) and lower temperatures. Cables that are marked with a conductor type that includes the letters "HH" have insulation that is for use in dry locations at temperatures as high as 90°C (194°F) as well as in wet locations at 75°C (167°F) and lower temperatures. Cables that are marked with a conductor type that includes "-2" have insulation that is for use in wet or dry locations at temperatures as high as 90°C (194°F).

1.3 Cables containing any conductor that is of a metal other than copper are marked to identify the metal as aluminum or copper-clad aluminum. Aluminum single-rated (see 4) Type USE or USE-2 cables containing other than solid 12, 10 or 8 AWG conductor(s) are of an EC-1350 grade aluminum alloy or a registered AA-8000 series electrical-conductor-grade aluminum alloy.
