Scope

This standard stipulates that the anti-staining power after acid treatment can be used to evaluate the sealing quality of anodic oxidation film. This standard is applicable to the inspection of anodic oxide films that are to be used in atmospheric exposure and corrosive environments, and is more suitable for the inspection of pollution-resistant oxide films. This standard is not applicable to the inspection of oxide films formed on high-copper and high-silicon (Cu>2%, Si>4%) aluminum alloys; oxide films sealed with potassium dichromate; Oxide film; dark oxide film; oxide film thickness less than 3 μm.
