UL Safety Testing Institute is the most authoritative in the United States and an international institution engaged in safety testing and certification in the world. UL certificate lookup is a non-compulsory certification in the United States, mainly for testing and certification of product safety performance, and its scope of certification does not include the EMC (electromagnetic compatibility) characteristics of the product.
UL1642 is a specification standard for the safety of lithium batteries launched by the United States Safety Testing Laboratory Corporation in October 1985. It is the most widely certified authoritative standard in the world for evaluating the safety and reliability of lithium batteries under various fault conditions, mainly for batteries. The main test items of UL1642 include room temperature short circuit test, short circuit test, overcharge test, extrusion test, heavy impact test, shock and vibration testing, vibration test, hot box test, temperature shock test, high altitude simulation test, ejection test, etc.
UL2054 is mainly for lithium battery packs or lithium battery packs. Suitable for primary (non-rechargeable) and secondary (rechargeable) batteries used as power sources in products. These batteries can consist of a single electrochemical cell or two or more lithium-ion cells connected in parallel or in series that convert chemical energy into electrical energy through chemical reactions.
(1) The UL listing mark is currently the most commonly used, and this type of mark is usually seen in the following categories of products: electrical appliances, calculator equipment, furnaces and heaters, fuses, power strips, smoke and carbon monoxide detectors, fire extinguishers and sprinkler systems, personal flotation devices such as life jackets and buoys, bulletproof glass and thousands of other products.
(2) The C-UL listing mark applies to products sold in the Canadian market. Such markings can be seen on the following types of equipment: electrical and computing equipment, vending machines, home burglar alarm systems, lighting fixtures, and many other kinds of products.
(3) The C-UL US listing mark meets both the requirements of the United States and Canada. UL's certificate report has no validity period, and is maintained according to the factory inspection and certificate maintenance fee. The audit factory is inspected every quarter, and audit factory records are required.
(1) The entire U.S. market pays great attention to product safety; Amazon's U.S. site also mandates that some products must have UL certification for batteries; consumers and purchasers will choose products with UL certification marks when purchasing products.
(2) UL has a history of more than 100 years, and the image of safety is deeply rooted in consumers and the government. If you do not sell products directly to consumers, middlemen will also require products to have UL certification marks to make products sell well.
(3) American consumers and purchasers have more confidence in the company's products.
(4) More than 40,000 political districts in the federal, state, county, and municipal governments of the United States all recognize the UL certification mark for batteries. For all types of battery testing methods, please inquiry us.
