The JIS H8503-1989 standard specifies a variety of test methods for the abrasion resistance of metal platings, including sand fall abrasion, jet abrasion, reciprocating abrasion, plate swirl/spin abrasion (Teerbar type) and two-wheel drive abrasion (Amsler type). These methods are designed to evaluate the wear resistance of platings by simulating friction abrasion under different conditions. The standard details the test device, specimen preparation, test conditions and operating procedures, providing a standardized process for testing the abrasion resistance of metal platings.
