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.
