There is no comparison between the glow-wire test and
the flame test.
The glow-wire test is an attempt to ignite the material
>from a non-flame source. I would guess that ignition
of a material largely depends on the type of flame-
retardant additive, i.e., whether or not it operates in
the gas phase or some other mechanism.
The UL 94 test is a measurement of the burning time
and the glowing time after flame ignition of the
material. In this test, all materials ignite; they
differ in the duration of burning after ignition.
Best regards,
Rich
