I have had it done with a sample PCB before. The copper an soldermask
shouldn't affect the flammability

Doug, do you mean the only the substrate or a PCB  with the copper and
soldermask in place?

Subject: PCB marked for UL 94V-0

Hello  group,

An interesting  question came up about validating printed circuit board raw
material.  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?
