What stamp or tag indicates that a product meets minimum safety standards?

The U.L. stamp or tag indicates that a product meets minimum safety standards, particularly in relation to electrical devices and equipment. Underwriters Laboratories (UL) is a well-respected and recognized safety organization that tests and certifies products to ensure they comply with specific safety criteria. This certification helps consumers and manufacturers identify products that have been rigorously tested for safety and performance, thus reducing the risk of electrical hazards.

The presence of the U.L. mark generally indicates that the product has undergone tests for shock, fire hazards, and other potential risks that may affect user safety. This mark carries significant credibility in various industries, making it essential for manufacturers that prioritize safety and compliance with regulatory standards.
