Your note: Hi all. I have a question to pose regarding UL and labelling requirements.
My company produces a number of ITE products which all use the same compliance label with customizations specific to each product (model name, electrical ratings, etc.). These customizations are imprinted on a generic label by a laser printer. The UL field engineer stated that he wants the UR (recognized component) symbol printed either in the waste area of the label sheet or somewhere on the packaging. The manufacturer's data sheet for the label material states that the label material and adhesive meet all requirements set forth by UL, CSA, and TUV. We have had permanency of print tests run on the labels (after printing information on them by the label supply company and by our laser printers), and UL is satisfied that the labels meet the requirements. My question is this: Now that we have run the tests, are we locked into this label supply company, or can we choose another vendor (who uses the same label material and printing processes) without having to perform the tests on the labels again? Thanks for any responses. Steve Chin StreamLogic Corp.

Any change in label stock and/or printing process used will require that new sample printed labels be submitted for additional review. George Alspaugh Lexmark International georgea @ lexmark.com
