Anodizing of aluminium and its alloys. Check for continuity of thin anodic oxidation coatings. Copper sulfate test Ingestion-build-58863 BS EN 61189-5-3 provides users1 Scope 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 m 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
