Are lithium-ion batteries UL listed?
Traditionally, battery cells have been certified to UL 1642, the Standard for Lithium Batteries.
What is UL certified battery?
Batteries with a UL Listing have been tested to meet nationally-recognized safety standards. They have been tested as complete final products, though complete components suitable for factory installation also can earn this designation.
Which certification is required for battery pack?
UN 38.3 certification is mandatory for the transportation of all lithium metal batteries and lithium-ion batteries by air, road or sea.
Is IEC 62133 mandatory?
Mandated by many IEC end-device standards, IEC 62133 is the de facto standard for international compliance. UN 38.3 transportation testing (see previous section) is an integral requirement, but does not need to be repeated.
Do batteries need to be UL listed?
Do my batteries need to be certified or listed by Underwriters Laboratories (UL)? No. Recently, some OEM’s have begun using the claim that batteries must be certified by UL as an artificial barrier to protect their battery sales. There is no requirement to have UL Listings on battery packs and most OEMs do not do it.
What is UL certification for?
UL stands for Underwriter Laboratories, a third-party certification company that’s been around for over a century. UL testing makes sure that wire sizes are correct or devices can handle the amount of current they claim to be able to. They also ensure that products are constructed correctly for the highest safety.
Is UL 2054 mandatory?
Although UL2054 is not a mandated test for products shipped into the US, it is often mandated by US end device standards and it is a pretty severe test as it requires a single fault to be applied on the battery pack.
Is UL 1642 mandatory?
UL certification is a non-compulsory certification in the United States, mainly testing and certification of product safety performance, and its certification scope does not include the product’s EMC (electromagnetic compatibility) characteristics.
Do batteries have to be CE marked?
Batteries do not radiate electromagnetic radiation and as such do not require CE testing. Their batteries do conform with all the relevant EC directives and regulations and as such are marked with the appropriate symbols.
What IEC 62133?
IEC 62133 defines the requirements and tests for secondary cells and batteries containing alkaline or other non-acid electrolytes and the batteries made from them. The standard IEC 62133 distinguishes between nickel and lithium-ion cells and batteries.
What IEC 61960?
IEC 61960-4:2020 specifies performance tests, designations, markings, dimensions and other requirements for coin secondary lithium cells and batteries for portable applications and backup power supply such as memory backup applications.
Is the UL standard based on ISO or IEC?
These UL Standards are based on IEC standards or ISO standards, and include the corresponding IEC text or ISO text. The price of these UL Standards reflects UL’s costs associated with securing the copyright for the IEC text or the ISO text in the US, as specified in the ANSI Sales and Exploitation Rights Policy for ISO and IEC Standards.
Who are the owners of CSA and UL?
UL is a registered trademark of Underwriters Laboratories Inc. CSA is a registered trademark of the Canadian Standards Association. NEC is a registered trademark of the National Fire Protection Association, Quincy, Mass. Cutler-Hammer and Eaton are federally registered trademarks of Eaton Corporation.
How are IEC ratings used to size a contactor?
CEC, the horsepower rating is used to size a contactor for a standard motor application. Although IEC contactors have ratings based on the IEC standard (such as the AC-3 current rating), these ratings are not recognized or considered when sizing according to UL508A, CEC or NEC applications. See example below: Example
