Describes test methods using following 3 kinds of abrasion apparatus: a) abrasive wheel wear test apparatus: determining the wear resistance and the wear index of anodic oxidation coatings on flat specimens of aluminium and its alloys; b) abrasive jet test apparatus: comparing the resistance to abrasion of anodic oxidation coatings on aluminium and its alloys with that of a standard specimen or, alternatively, a reference specimen, by use of a jet of abrasive particles; c) falling sand abrasion apparatus: determining the abrasion resistance with falling sand applied to thin anodic oxidation coatings.
