UL certification is a non-mandatory certification in the United States, mainly for the detection and certification of product safety performance, and its certification scope does not include the EMC (electromagnetic compatibility) characteristics of the product.
The entire U.S. market attaches great importance to product safety. Amazon USA also requires some products to have UL certification. Consumers and purchasing units will also choose products with UL certification marks when purchasing products. Therefore, if your products are UL certified before exporting to the United States, it will be very beneficial for you to seize the US market.
Ancogen takes you to understand what are the standards for battery products to apply for UL projects?
UL1642 is mainly applicable to primary (non-rechargeable) and secondary (rechargeable) lithium batteries.
For UL1642 required information:
1. Provide the information of the main model and the reporting model, which is used for the preparation of the report, including the required pictures;
2. Provide basic product model information for testing and reporting sampling selection. All models need to be filled in;
3. Provide electrolyte composition;
4, provide a cycle plan, applicable to the first application of the main model, cycle test.
