Abstract

This Part of this European Standard specifies a method of test for comparing the resistance to abrasion of anodic oxidation coatings on aluminium and ist alloys with that of a standard specimen or, altenatively, a reference specimen, by the use of a jet of abrasive particles. The mean specific abrasion resistance of an anodic oxidation coating can be determined by the method described. NOTE 1: Different batches of the same abrasive are liable to give different results and for this reason the test is a comparative one. NOTE 2: With suitably designed abrasive jets, and film thickness measuring devices with a small probe, it is possible to conduct a depth survey which indicates how abrasion resistance varies through the coating thickness (see annex B). However, this property is measured preferably using the abrasive wheel wear test method (EN 12373-9) 1). The method described is applicable to all anodic oxidation coatings of thickness not less than 5 um on aluminium or its alloys. It is primarily intended for surfaces which are not flat. If suitable flat test surfaces are available, the abrasive wheel test method (EN 12373-9) 1) is the preferred method. Production components can be tested without cutting if the apparatus chamber can accommodate these. NOTE 3: The method is particularly suitable for small test pieces because the individual test area required is only about 2 mm in diameter. 1) See foreword.
