Annex A (normative) Preparation of standard specimen

Defines a method of test for determining the wear resistance and the wear index of anodic oxidation coatings on flat specimens of aluminium and its alloys by means of an abrasive wheel wear test apparatus. Not applicable to concave or convex specimens; these may be examined using the abrasive jet test method (see EN 12373-10) which will give an average value for the abrasion resistance of the coating.
