▍Introduction
The Occupational Safety and Health Administration (OSHA) under the U.S. Department of Labor requires products used in the workplace to be tested and certified by a nationally recognized laboratory before they can be sold in the market. The testing standards used include American National Standards Institute (ANSI); American Society for Testing and Materials (ASTM); Underwriters Laboratory (UL); and research organization standard for mutual recognition of factories.
▍Overview of NRTL, cTUVus, and ETL
● NRTL is short for Nationally Recognized Testing Laboratory. A total of 18 third-party certification and testing institutions have been recognized by NRTL, including TUV, ITS and MET so far.
● cETLus Mark: North America Certification Mark of Electrical Testing Labs of United States.
● cTUVus Mark：North America Certification Mark of TUV Rheinland.
