UL Certified / UL Approved Labels
What are UL recognized labels?
UL 969 standard is a Making and Labeling system. All Underwriters Laboratory labels (UL labels) must meet this standard. To ensure UL label print legibility, resistance to defacement and adhesion to end-products, all UL label components have to go through extreme testing. UL will add your label and its components to an approved file after passing the tests, and will continue testing monthly to validate approval on an ongoing basis.
