Hi Ilan:
I was looking for a viable comparison between glow wire and the UL94
flammability rating. The point of this little comparison is to bypass the
glow wire test for materials, which are properly rated for UL94.
There is no comparison between the glow-wire test and
the flame

Would it be correct to say that a V0 or 5V UL
rated material will pass the
glow wire test automatically

The test methods are entirely different

The test methods are entirely different and, therefore, the
result are not directly comparable. If you were to take
enough time to review all available data, you might be able
to derive a statistical correlation between flammability
classification and glow wire results, but you won't
Guys
I am having hard time trying to compare between flammability rating
according to UL and the glow wire test. In many of the safety standards (for
example IEC335 series) a glow wire test is required and UL94 rated materials
are not an option (or maybe they are?).
