This standard specifies the method of checking the insulation of anodized coating of aluminium and its alloys to determine the breakdown potential. This standard applies to cases where anodizing is carried out for purposes of electrical insulation. (The breakdown voltage may be used for approximate determination of thickness of anodic coating for control purposes. )
