UL (Underwriters Laboratories Inc.)
UL is a non-profit examination institution which was established by U.S. Association of Fire Underwriters in 1894. Although it is voluntary to get UL-approval, a lot of electronic products, electric parts or resin material are UL-approved. UL certification is evaluated based on UL standards, and generally there is a listing mark for finished products and a recognized component mark for parts or material.
