Which method (e.g. EN 15205, etc) do you use to confirm the presence or absence of hexavalent chromium substances on a metal coating?
Thanks,

Alex.

If one receives a metal part to test then (assuming that there is no prior knowledge if the materials is a stainless steel, etc) how to decide which method / standard to use?
