scope:

Specifies 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 test apparatus. The wear resistance or the wear index of the layers of oxide near the surface, or of the whole oxidation coating thickness, or of any selected intermediate zone, can be determined by the method described. For most purposes the wear index or the mass wear index will be the most appropriate characteristic to determine. The method is applicable to all anodic oxidation coatings of thickness not less than 5 µm on flat aluminium specimens.
