What Does UL Listed Mean?

The UL Mark, sometimes called an Underwriters Laboratory Mark, on a product means that UL has tested and evaluated representative samples of that product and determined that they meet UL requirements. Under a variety of programs products are periodically checked by UL at the manufacturing facility to make sure they continue to meet UL requirements. 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. In addition to these marks, UL also provides access to the marks required in a number of other key world markets.

The UL Listing Mark is one of the most common UL Marks. If a product carries this Mark, it means UL found that representative product samples met UL's safety requirements. These requirements are primarily based on UL's own published standards for safety. This type of Mark is seen commonly on appliances and computer equipment, furnaces and heaters, fuses, electrical panel boards, smoke and carbon monoxide alarms, fire extinguishers and sprinkler systems, personal flotation devices, bullet resistant glass, and thousands of other products.
