ASTM D6037-18

1.1 This test method covers procedures for evaluating the relative mar resistance of high gloss coatings. Two test methods are included. Test Method A uses a device that rotates the test specimen on a vertical axis, against the sliding rotation of two abrading wheels. Test Method B uses a device that reciprocates a specimen in a horizontal plane over a stationary wheel that has been fitted with abrasive paper and is advanced after each double stroke. Either method can be used to evaluate the dry abrasion mar resistance of coatings applied to planar, rigid surfaces. Each test method provides good discrimination between highly mar resistant coatings.
