Scope (English)

This standard is adopted by reprinting ISO 2085:2018(E) — Anodizing of aluminium and its alloys — Check for continuity of thin anodic oxidation coatings — Copper sulfate test, in an identical manner, using the original English-language version of ISO as the primary reference. It specifies a method for testing the continuity of thin anodic oxide coatings on aluminium and aluminium alloys by exposure to copper sulfate solution. This test method has limitations when applied to anodic oxide coatings less than 5 µm thick or to deformed coatings, including coatings on coiled products. Note: This test provides a rapid method for checking the continuity of thin anodic oxide coatings on aluminium and aluminium alloys. In cases where visible defects are present on the coated surface, this method may help determine whether those defects represent bare metal areas without any coating.
