BS EN ISO 2085:2018

This standard BS EN ISO 2085:2018 Anodizing of aluminium and its alloys. Check for continuity of thin anodic oxidation coatings. Copper sulfate test is classified in these ICS categories:

• 77.120.10 Aluminium and aluminium alloys
• 25.220.20 Surface treatment

This document specifies a method for checking the continuity of thin anodic oxidation coatings on aluminium and its alloys by a copper sulfate contact test.

The use of this method is limited to anodic oxidation coatings of thickness less than 5 µm or coatings that have been deformed, which includes those produced by coil anodizing techniques.

NOTE The method described enables a rapid check to be made for the continuity of a thin coating of aluminium oxidation on aluminium and its alloys. In cases of doubt regarding a visible fault on the surface of a coating, the use of this method makes it possible to verify whether the fault corresponds to a local gap in the coating that exposes bare metal.
