Polycarbonate Spot Test

[swall]

Is there a burn test or other spot test for identifying polycarbonate? I have some clear sheet material and don't know if is is polycarbonate or acrylic. And it is a little too thick for a cold bend test.

Cut a thin sliver off and burn it and carefully smell a whiff of the smoke.

Acrylic smells sweet. PC smells oily or acrid. Also acrylic burns profusely and PC barely burns and easily extinguishes.

If you have a known sample of each to test first, the smell difference is unmistakeable.
