What is Underwriters Laboratories (UL)?

Underwriters Laboratories Definition

Underwriters Laboratories (UL) is a safety organization that sets industry-wide standards for new products. UL testing ensures that wire sizes are correct and that electronics devices can handle the amount of current claimed by the manufacturer. UL is one of several companies approved to perform safety testing by the Occupational Safety and Health Administration (OSHA), but doesn’t always test the products themselves. UL can authorize manufacturers to conduct their own tests and UL follows up regularly to ensure the proper product tests and guidelines are being followed. The UL stamp or mark is placed on products after testing is passed.
