ISO 2085:1976, Anodizing of aluminium and its alloys - Check of continuity of thin anodic oxide coatings - Copper sulphate test

The use of the copper sulphate test is limited to oxide coatings having a thickness less than 5 m. This test enables a rapid check. It makes it possible to verify whether a fault on the surface of the coating corresponds to a local gap in the coating (i.e. revealing bare metal).
