There have been some good tips on checking UL compliance. Every PWB that is UL recognized needs to be stamped with the company name (or mark) and the style of marking of the rating, 94 V-2, 94 V-0, etc. One way that we check is by using UL's web site. Here is the link to where you can search on the company information. http://database.ul.com/cgi-bin/XYV/template/LISEXT/1FRAME/index.htm We utilize this site extensively and it has proven vary valuable, not only for PWBs, but for all UL Listed or Recognized components. Thanks, Bryan.

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.
