ULKennzeichnungen

UL Kennzeichnungen, also known as Underwriters Laboratories (UL) listings, are a system of safety compliance markings used in the United States and Canada. They are issued by Underwriters Laboratories, a global safety certification company, to indicate that a product, material, or installation meets specific safety standards. UL listings are widely recognized and accepted in various industries, including electrical, electronics, and construction.

The UL marking typically includes a UL logo, a file number, and a category number. The file number is unique to each product and is used to identify the specific safety standards that the product has met. The category number indicates the type of product or material, such as electrical equipment, wiring devices, or building materials.

UL listings are based on a rigorous testing and certification process. Products must undergo extensive testing to ensure they meet UL's safety standards, which are developed in collaboration with industry experts and regulatory bodies. Once a product passes these tests, it is assigned a UL listing and can be sold in the United States and Canada.

UL listings are not mandatory, but they are often required by manufacturers, distributors, and regulatory bodies to ensure that products meet certain safety standards. They provide consumers with confidence that the products they purchase have been tested and certified for safety.
