Steve Chin asked about labeling.
>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. Is the UL FUS Rep. asking for a UR ligature on the label for the label's sake, or for the products' sake? If for the label, I'd say they're off base, since you probable don't intend to sell the labels independently of you products. You probably went through an Unlisted Component investigation of the label stock/laser printer combination and the UR marking would be inappropriate and a misuse of the mark. If for your products sake, I've noticed that UL's FUS Reps. like to see that in end product factory inspections. Marking your product with the UR could be a service to your customers. On the other hand, for ITE, there're no requirements that you use the UR on your products. Proof of Recognition is your company name, trademark or other unique marking identifying your company (registered with UL), and the model or cat. no. of the product, whether or not you have the UR on the product. >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? Tony Fredricksson's answer is quite right, if the label stock is from a different label stock mfg. (for instance, both are a particular generic material and specific adhesive, but the materials are made by different companies than your vendors'). However, the same applies to your new vendor, even if they use the same label stock directly from your stockroom and the same laser printer right off of your desk and using the same methods. In the latter case, you'd likely get away with an abbreviated test program. The idea behind this (whether weak or strong) is to make certain the new vendor can do the job at least as well as you. Like Tony said, call UL and get the skinny. Regards, Peter L. Tarver Nortel [email protected]
