MARKS FOR UL’S LISTING SERVICE
If a product carries one of these marks, it means UL found that representative product samples met UL’s requirements. These marks are 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.
There are multiple variations of marks for UL’s Listing service, some of which are for use in the United States, others for use in Canada and still others for use in both markets. Products carrying marks for Canada have been evaluated to Canadian safety requirements, which may be somewhat different from U.S. safety requirements. A combination mark indicates compliance with both Canadian and U.S. requirements.
These marks appear on end products and complete components suitable for factory and field installation. All of the products carrying these marks are covered by our Follow-Up Services program to determine that products continue to be manufactured in compliance with UL’s safety requirements.
There are two options for the marks for UL’s Listing service, as noted below.
