Hi Doug, My experience with this is that most reputable PCB vendors are true to their word. The liability involved in falsely stating compliance is just too great. The other thing is to select PCB vendors that are listed with an agency (UL,CSA, etc.). The PCB vendor has to put their name or logo on the PCB as well as the flame rating. Copies of these logos used to be in the UL yellow book. If you have a PCB marked as V-0 and there is no manufacturers marking on the board, I would be suspicious. To satisfy yourself, you can send samples of the PCB to a testing lab (UL, CSA, etc), and for a suitably exhorbitant fee they will do the tests for you. The other alternative is to get the vendor to provide you with a test report from the agency

In searching for alternate vendors we provide a spec that V-0 material is required and a UL V-0 stamp be placed on the board. The question is, how do I independently validate the material used, since a vendor could theoretically choose whatever they want and stamp it as V-0? -doug Douglas E.
