<p>ISO 8251:2011 specifies the following three test methods: a) <b>a</b><b>brasive-wheel-wear test</b><b> method</b>, determining the wear resistance and the wear index of anodic oxidation coatings on flat specimens of aluminium and its alloys; b) <b>abrasive jet test method</b>, 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) <b>f</b><b>alling sand</b><b> abrasion </b><b>method</b>, determining the abrasion resistance with falling sand applied to thin anodic oxidation coatings.</p>
<p>The use of these methods for coatings produced by hard anodizing is described in ISO 10074.</p>
