Underwriters Laboratories (UL)
was founded in 1894 and is an independent organization that tests products, components, materials and systems for your “specific requirements”. If the products meet the specific requirements, they can bear the UL test mark. However, only as long as the specified standards are adhered to. A review of this takes place at regular intervals unannounced in our production facility in Shanghai.
The UL-Recognized-Component-Mark indicates that the UL-recognized component can be used in a product or system that bears the UL-Listing mark.
