UL

A UL certificate, also known as a UL Listing or UL Mark, is a certification mark issued by Underwriters Laboratories (UL), a global safety certification organization. The UL certificate indicates that a product has been tested and meets UL's safety requirements, which are based on national and international safety standards.

UL's certification process involves testing products in UL's laboratories, conducting quality control inspections of manufacturing facilities, and periodically retesting products to ensure continued compliance with safety requirements. UL also evaluates and tests components and materials used in products, such as wires and cables, to ensure their safety and performance.

A UL certificate can be an important factor for manufacturers seeking to sell their products in certain markets, particularly in North America, where UL is a recognized and trusted safety certification organization. A UL certificate can also provide reassurance to consumers that a product has been independently tested and meets recognized safety standards.
