How are UL Standards developed?

UL Standards are developed under a process that provides for participation and comment from the affected public as well as industry. The process takes into consideration a survey of known existing standards and the needs and opinions of a wide variety of interests concerned with the subject matter of the standard. Manufacturers, consumers, government officials, industrial and commercial users, inspection authorities and others provide input to UL. For further details, visit Develop Standards on the UL Standards web pages.
