Short for Underwriters’ Laboratories, which is a standards and testing agency financed by the insurance industry. The purpose of UL testing is to ensure fire safety of electrical equipment. A device which has been tested and passed by UL will have the familiar round label of certification. UL approval has nothing to do with the audio quality or the functionality of a device. In some states UL approval is a requirement in order to sell equipment that uses electricity.
