UL Listing (U.S. Safety Scheme) Factory Suppliers Manufacturers Quotes

UL Listing (U.S. Safety Scheme)

This scheme may also be referred to in some historical texts as the UL Listing, Classification and Recognition Program. In this scheme, tangible products are certified to requirements for safety that are associated with fire, shock and casualty hazards.

 

Samples of products are tested, inspected, examined and otherwise evaluated to gather information that demonstrates the product fulfills applicable requirements. Fulfillment of all applicable requirements must be demonstrated before authorization is granted to apply a certification mark used in this scheme.

 

Visits to factories that apply marks to products certified in this scheme are completed periodically to verify product and production characteristics as an assurance the original demonstration of fulfillment of requirements continues to be valid. For some products, factory samples are selected for retesting.

 

Changes to certified products are considered and, if needed, additional tests, inspections, examinations or other evaluations are completed to demonstrate a product continues to fulfill requirements and authorization to apply a mark can continue. Unresolved noncompliances with requirements result in termination of authorization to apply the mark.

 

Use of the mark can also be terminated voluntarily. The use of the markings shown and explained below is authorized and controlled by UL LLC to indicate a product has been certified using the U.S. Safety Scheme. A directory of certified products is available online via the Online Certifications Directory. Only products bearing the mark are certified.
