Test adherence for electroplating on ABS

Hello, I'm working in my thesis topic and it's about a electroplating on ABS, we have some troubles because we don't know which is the most efficient test of adherence for electroplating Ni, Cu and Cr on this plastic, actually we need a test that not be destructive with the pieces. Could you help us to find a correct test? The electroplating is only for decorative ends.

Thank you

You do it on scrap parts. There are tape tests, but not for your needs as I read it.

Thermal cycling or thermal shock is a good way to test for adhesion. It is only a pass/fail test, though, and does not isolate adhesion. If you fail, you'll get some sort of delamination or cracking.

(Metal cracking can actually indicate good adhesion.)
