What is the US NRTL certification?

The United States NRTL certification refers to the product safety certification issued by a Nationally Recognized Testing Laboratory (NRTL) recognized by the Occupational Safety and Health Administration (OSHA). Common certifications on the market such as UL certification, ETL certification, and cTUVus certification are all types of NRTL certification, differing only in the issuing bodies. NRTLs are independent third-party organizations authorized by OSHA to conduct safety testing and certification to ensure that specific products meet U.S. safety standards. OSHA has established a series of safety standards aimed at protecting workers in the workplace from potential injuries and hazards. According to OSHA regulations, certain types of equipment and products must undergo NRTL testing and certification before use, which typically includes electrical equipment, fire detection instruments, personal protective equipment, etc. The NRTL certification process involves a series of safety tests on the product to verify whether they meet specific safety standards. Once the product passes the tests, the NRTL will grant it a certification mark, indicating that the product has been tested and meets safety requirements. This certification mark usually needs to be affixed to the product so that consumers can identify it. For manufacturers, obtaining NRTL certification is not only a legal requirement but also an important market access condition that helps improve product credibility and market competitiveness. For consumers, the NRTL certification mark is an important guarantee of product safety.
