UL Recognized Component Mark

UL Recognized Component Mark Get Best Quote These are Marks consumers rarely see because they are specifically used on component parts that are part of a larger product or system. These components may have restrictions on their performance or may be incomplete in construction. The component recognition marking is found on a wide range of products, including some switches, power supplies, printed wiring boards, some kinds of industrial control equipment and thousands of other products. Just as with the UL Listing and Classified Marks, there are three variations of UL’s Recognized Component Mark: one for the United States only, one for Canada only and one for both the United States and Canada. The C-UR Mark is applied to components only used in the Canadian market. Components with this type of Mark have been evaluated to Canadian standards. The optional C-UL-US Component Recognition Mark indicates compliance with both Canadian and U.S. requirements. UL encourages manufacturers distributing UL Recognized Components evaluated for both countries to use this combined Mark, but they may continue using separate UL Recognized Component Marks for the United States and Canada. Components covered by UL’s Recognized Component program are intended to be installed in another device, system or end product. They are to be installed at the factory, not in the field and they may have restricted performance capabilities that limit their use. When a complete product or system containing UL Recognized Components is evaluated, the end-product evaluation process can be streamlined. The UL component evaluation process may include a construction examination and testing. Guidelines addressing the suitability of a component when used in an end product are noted in UL’s test report as conditions of acceptability.
