Flamability and Plastics

[Jester]

When using a plastic enclosure for electronic equipment, our local safety body performs a flame test, to make sure the plastic will self extinguish when the flame source is removed. In the past some of the enclosures we have chosen pass while others have failed requiring redesign.

I don't recall the rating of the acceptable plastic, does anyone have insight on this?

I'm looking at an enclosure that is an ABS/PC blend with a UL94 V-0 flammability rating.

I'm not sure what your question is. UL94 is a flammability rating, but you already know that. So, what's the question? You seem to already know what you want.

Maybe this will help

Yes, that is helpful, V-0 looks like it should pass the test. We had some enclosures in the past that would just keep on burning.

Thank you.
