LMATS is NATA accredited to perform Copper Sulphate test in accordance with ASTM A380.

This method is recommended for the detection of metallic iron or iron oxide on the surface of austenitic 200 and 300 Series, the precipitation hardening alloys, and the ferritic 400 Series stainless steels containing
16% chromium or more. It is not recommended for the martensitic and lower chromium ferritic stainless steels of the 400 Series since the test will show a positive reaction on these materials.

This test cannot be applied to surfaces of items to be used in food processing.
