David and Gary -
Gary has the name correct, but the difference in rating is
derived due to complications related to the test method.
VTM materials tend to curl up, wilt or shrink away from a
flame when cut into test blanks normally used for the V-x
small scale material testing. To overcome
. If I
remember correctly it has to be tested mounted to a madril of some sort to
determine is ratings.

What does UL 94 VTM-0 mean? I saw it in a spec for thin insulating plastic.
Thanks,
David.
