Over the past couple of years UL received several reports of misuse and misrepresentation of the UL Classification Mark on sign retrofit kit components. In addition AHJs have often reported to UL that retrofit kit installation instructions were rarely available to them for review during the permitting phase of conversion projects.
After consultation with several members of the sign industry and the Regulatory community, UL announced in a bulletin to Subscribers dated May 4, 2018 that effective January 1, 2019, the Certification Mark for all new UYWU Sign Conversion Retrofit Kits will only be authorized to appear on the kit’s installation instructions.
This move of the sign retrofit kit Certification Mark to the installation instructions will eliminate the need for any additional Classification Marks to appear on other components of the kit and should result in the installation instructions being available as mandatory proof of sign retrofit kit Certification.
