Dear Jerome, Try http://www.ul.com./about/index.html and/or http://www.ul.com./info/standrds/part1/1-595.htm etc. They may be helpful. In addition, I would like to comment that both UL and 94-V0 are not the name of standard. UL is ... see the http above. 94-V0 is the highest ranking level that is defined by one of the famous UL's standard so called "UL94"- Tests for Flammability of Plastics Materials for Parts in Devices and Appliances. Therefore, passing UL or 94-V0 means the item (materials, components, enclosure etc.) complies with the requirements noted in UL's standards.
