This International Standard lays down a method for specifying decorative and protective anodic oxidation coatings on aluminium. It defines the characteristic properties of anodic oxidation coatings on aluminum, lists methods of test for checking the characteristic properties, specifies minimum performance requirements and gives information on the grades of aluminium suitable for anodizing and the importance of pretreatment to ensure the required appearance or texture of the finished work. It is not applicable to a) non-porous oxidation coatings of the barriar layer type; b) oxidation coatings by chromic acid or phosphoric acid anodizing; c) oxidation coatings intended merely to prepare the substrate for subsequent application of organic coatings or electrodeposition of metals; c) "hard anodized" coatings, used mainly for engineering purposes, for which abrasion and wear resistance are the primary characteristics (see ISO 10074).
