Corrosion tests on E-coated and powder coated parts

[EminaTr]

Hello,

I have a doubt about corrosion testing. If standard norm says that we need to e-coat and then powder coat the piece,do we have to do testings of e-coat, or just final powder coating?

More context would be helpful but if the durability of your final part is all that matters then that's all I would test.

If you want to know how effective e-coat is, then just test that. Depends what you are wanting to learn.
