"Underwriters Laboratories Inc. (UL) is an independent, not-for-profit product-safety testing and certification organization. We have tested products for public safety for more than a century.

Since our founding in 1894, we have held the undisputed reputation as a leader in product-safety testing and certification within the United States. Building on our household name in the United States, UL is becoming one of the most recognized, reputable conformity assessment providers in the world. Today, our services extend to helping companies achieve global acceptance, whether for an electrical device, a programmable system, or an organization's quality process.

UL's Listing Service is the most widely recognized of UL's safety certification programs. The UL Listing Mark on a product is the manufacturer's representation that samples of that complete product have been tested by UL to nationally recognized Safety Standards and found to be free from reasonably foreseeable risk of fire, electric shock and related hazards.

The UL Marks may be only used on or in connection with products certified by UL and under the terms of written agreement with UL."

"UL introduced this new Listing Mark in early 1998. It indicates compliance with both Canadian and U.S. requirements. The Canada/U.S. UL Mark is optional. UL encourages those manufacturers with products certified for both countries to use this new, combined Mark, but they may continue using separate UL Marks for the United States and Canada."
