Underwriters Laboratories Inc. (UL), Northbrook, Ill., celebrates the 100th anniversary of its first safety standard. UL has published nearly 900 Standards for Safety since 1903 and its familiar mark appears on billions of products each year.

UL’s first Standard for Safety, UL 10A for Tin-Clad Fire Doors, has grown into the 886 current UL standards, each developed and maintained with input by UL engineers in conjunction with industry, government agencies, regulatory authorities, members of academia, and consumer advocates.

“UL has played an integral role in establishing the U.S. safety system by bringing together experts from varied fields to develop product standards,” says Robert A. Williams, UL’s director of Standards. “As a result, UL Safety Standards are recognized for establishing the basic safety principles in North America.”
