UL1642 standard is a safety standard specifically formulated by Underinsurance Laboratories (UL) of the United States for lithium batteries, which has extremely strict regulations on the design, testing and manufacturing processes of batteries. The core objective of this standard is to ensure the safety of lithium batteries under various extreme conditions and prevent dangerous accidents such as fires and explosions.

The test items it covers are rich and rigorous, including thermal abuse tests, which simulate the performance of batteries in high-temperature environments; Abnormal charging test to examine the stability of the battery under incorrect charging methods; Compression test, to evaluate the safety of the battery when it is subjected to external force compression; Heavy object impact test to verify the battery's endurance when subjected to impact, etc. Through these comprehensive tests, the safety of lithium batteries under extreme conditions can be guaranteed to the greatest extent.

For lithium batteries that want to enter the US market, although UL1642 certification is a voluntary certification, it is of great significance. The U.S. customs releases goods with the "UL" mark more quickly, while those without the mark will face a complex inspection process. In the event of a safety accident, the U.S. Consumer Product Safety Commission will use UL standards as the basis for judgment. Furthermore, many American sellers, in order to avoid trouble, will directly refuse to sell goods without the "UL" mark. Therefore, UL1642 certification has become an important boost for lithium batteries to smoothly enter the US market.

If enterprises have any questions or needs regarding UL1642 certification, professional certification service agencies can provide corresponding support to help them complete the certification process more smoothly and pave the way for their products to enter the US market.
