Description:

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.

Scope

This clause of Part 1 is replaced by the following.

This part of IEC 60335 deals with the safety of electric heat pumps, including  sanitary hot water heat pumps,  air conditioners, and  dehumidifiers incorporating motor-compressors and  hydronic fan coils units , their maximum  rated voltages

being not more than 250 V for single phase appliances and 600 V for all other appliances.

Partial units are within the scope of this International Standard.

Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

The appliances referenced above may consist of one or more factory-made assemblies. If provided in more than one assembly, the separate assemblies are to be used together, and the requirements are based on the use of matched assemblies.

NOTE 101 A definition of ‘motor-compressor’ is given in IEC 60335-2-34, which includes the statement that the term motor-compressor is used to designate either a hermetic motor-compressor or semi-hermetic motor-compressor.

NOTE 102 Requirements for refrigerating safety are covered by ISO 5149-1, ISO 5149-2, and ISO 5149-3. Requirements for containers intended for storage of the heated water included in sanitary hot water heat pumps are, in addition, covered by IEC 60335-2-21.

This standard does not take into account refrigerants other than group A1, A2L, A2 and A3 as defined by ISO 817 classification, A2L refrigerants

are limited to those of a molar mass of more than or equal to 42 kg/kmol based on WCF – Worst Case Formulation as specified in ISO 817.

This standard specifies particular requirements for the use of flammable refrigerants. Unless specifications are covered by this standard, including the annexes, requirements for refrigerating safety are covered by ISO 5149.

The parts of ISO 5149 of particular concern to this standard are as follows:

• ISO 5149-1:2014, Refrigerating systems and heat pumps – Safety and environmental requirements – Part 1: Definitions, classification and selection criteria.

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.

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.

Notes:

Scope

This clause of Part 1 is replaced by the following.

BATTERY-OPERATED APPLIANCES

and other d.c. supplied appliances are within the scope of this standard. Dual supply appliances, either mains-supplied or battery-operated, are regarded as

BATTERY-OPERATED APPLIANCES

when operated in the battery mode.

This International Standard deals with the safety of electric shavers, hair clippers and similar appliances intended for household and similar purposes, their

RATED VOLTAGE

being not more than 250 V.

NOTE 101 Examples of similar appliances are epilators and those appliances used for manicure, and pedicure.

Appliances not intended for normal household use, but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops and on farms, are within the scope of this standard.

NOTE 102 Examples of such appliances are ANIMAL CLIPPERS, ANIMAL SHEARERS and appliances for hairdressers.

As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account

– persons (including children) whose

• physical, sensory or mental capabilities; or

• lack of experience and knowledge

prevents them from using the appliance safely without supervision or instruction;

– children playing with the appliance.

NOTE 103 Attention is drawn to the fact that

– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;

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

NOTE 104 This standard does not apply to

– 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);

– massage appliances (IEC 60335-2-32);

– appliances for medical purposes (IEC 60601).

This International Standard deals with the safety of electric shavers, hair clippers, epilators and similar appliances intended for household and similar purposes, their

RATED VOLTAGE

being not more than 250 V and intended to be installed or used in accordance with NFPA 70, National Electrical Code (NEC).

Hair clippers and shavers incorporating a suction feature to collect clippings or shavings during operation are also covered by this standard.

– lather makers (UL 499);

– barber shop vacuum cleaners for use on persons (UL 1017)

– manicure, pedicure, or personal grooming appliances used for similar purposes (UL 859). However, hair clipping and shaving appliances supplied with manicure, pedicure, or other similar attachments or accessories are investigated under these requirements and such additional requirements as are applicable to the appliance under consideration.

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.

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.

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:

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.

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.

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".

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.
