This document specifies the following tests:<\/p>\n

    \n
  1. \n

    abrasive-wheel-wear test, determining the abrasion resistance of anodic oxidation coatings with abrasive wheel on flat specimens of aluminium and its alloys;<\/p>\n<\/li>\n

  2. \n

    abrasive jet test, determining the comparative abrasion resistance of anodic oxidation coatings with jet of abrasive particles on anodic oxidation coatings of aluminium and its alloys;<\/p>\n<\/li>\n

  3. \n

    falling sand abrasion test, determining the abrasion resistance of anodic oxidation coatings with falling sand on thin anodic oxidation coatings of aluminium and its alloys.<\/p>\n<\/li>\n<\/ol>\n

    The use of abrasive-wheel-wear test and abrasive jet test for coatings produced by hard anodizing is described in ISO 10074.<\/p>\n
