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.

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.

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.

Household and Similar Electrical Appliances - Safety - Part 2-40: Particular Requirements for Electrical Heat Pumps, Air-Conditioners and Dehumidifiers

Notes:

Summary of Topics

This new fourth edition ANSI/UL 60335-2-40 dated December 15, 2022 is an adoption of IEC 60335-2-40, Edition 6.0 issued by the IEC January 2018. Please note that the National Difference document incorporates all of the national differences for UL 60335-2-40.

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.

• ISO 5149-2, Refrigerating systems and heat pumps – Safety and environmental requirements – Part 2: Design, construction, testing, marking and documentation;

• ISO 5149-3:2014, Refrigerating systems and heat pumps – Safety and environmental requirements – Part 3: Installation site.

Supplementary heaters , or a provision for their separate installation, are within the scope of this standard, but only heaters which are designed as a part of the appliance package, the controls being incorporated in 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;

• for appliances subjected to pressure, additional requirements may be necessary;

• in many countries, additional requirements are specified, for example, by the national health authorities responsible for the protection of labour and the national authorities responsible for storage, transportation, building constructions and installations.

NOTE 104 This standard does not apply to

• humidifiers intended for use with heating and cooling equipment (IEC 60335-2-88);

• appliances designed exclusively for industrial processing;

• 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).

This part of IEC 60335 deals with the safety of electric heat pumps, including hot water heat pumps, air conditioners, and dehumidifiers incorporating motor-compressors, and hydronic fan coils units, their maximum rated voltages being not more than 300 V for single phase appliances and 15 000 V for all other appliances. Partial units are within the scope of this Standard.

This standard does not take into account refrigerants other than refrigerant safety groups as defined by ISO 817 or ANSI/ASHRAE 34 as follows:

  1. a) A1; and

  2. b) B1, B2L, B2, B3 [(for use in appliances installed in machinery rooms as defined in accordance with ANSI/ASHRAE 15 (USA) or CSA B52 (Canada), or outdoors only)]; and

  3. c) A2L, A2, and A3, refrigerants with a molar mass not less than 42 kg/kmol based on nominal composition.

Replace “ISO 5149” with “ANSI/ASHRAE 15 (USA) and CSA B52 (Canada)”.

All references to ISO 817 in this Part 2 also apply to ANSI/ASHRAE 34. ANSI/ASHRAE 34 shall take precedence over ISO 817.

Energy Storage Systems and Equipment

Notes:

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).

Notes:

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.

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.

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.

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.

1.12 These requirements also cover electrically tripped and/or operated devices that have been investigated to determine their acceptability for ground-fault protection when combined with ground-fault sensing and relaying equipment as follows:

  1. a) Switches for use with Class I ground-fault sensing and relaying equipment including those devices that are capable of interrupting 12 times their rated current or that have integral means intended to prevent disconnecting at levels of fault current exceeding the contact interrupting capability of the switch.

  2. b) Switches for use with Class II ground-fault sensing and relaying equipment are capable of interrupting at 10 times their rated current and are for use in ground-fault protection systems where means intended to prevent disconnecting levels at fault current exceeding the contact interrupting capabilities of the switch are incorporated within the ground-fault sensing and relaying equipment.

1.13 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this standard is maintained. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard shall not be judged to comply with this standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.

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.
