Hi Brian:
> - CoC from plastic component supplier that is not recognized molder. I simply did not accept a non-recognized molder. If we want to use a non-recognized molder, I accept parts provided that the molder can provide documents showing he is in process of becoming a recognized molder. I demand a copy of all correspondence between the molder and UL. And, he labels the parts as required by the UL recognition process (except, of course, for the UL manufacturer's code until he completes the recognition). All my part drawings include notes that the material must be UL-recognized and the molder must be UL-recognized. The notes also specify the material flame-rating. > - processed wire tags from re-spoolers. I, too, have done this. Follow the UL process, or don't buy from that supplier. Specify in notes to the drawings. > - document audits from suppliers having no agency recognition. I don't accept non-recognized suppliers. If they want my business, then they must be recognized. > - labeling requirements for re-packaged chemicals. If required by UL or equivalent. Again, specified in the drawing notes. > - EMC re-test for some changes of PCB layout. Yes, of course. > - update of CB report when values on some safety-critical components > changed. In most cases, values are not critical and should not be a part of a CB report. Study the CB report and get the values taken out unless the cert house can prove that the value is critical to safety. If the value is critical to safety, then the CB report must be updated.
