1、Designation:D6037131Standard Test Methods forDry Abrasion Mar Resistance of High Gloss Coatings1This standard is issued under the fixed designation D6037;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A num

2、ber in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEReference to research report was added editorially to Test Method B in August 2013.1.Scope*1.1 This test method covers procedures for evaluating the

3、relative mar resistance of high gloss coatings.Two testmethods are included.Test Method A uses a device thatcontains a rotating specimen holder and two abrasive wheels.Test Method B uses a device that contains a reciprocatingspecimen holder and a single wheel that has been fitted withabrasive paper.

4、Either method can be used to evaluate the dryabrasion mar resistance of coatings applied to planar,rigidsurfaces.Each test method provides good discrimination be-tween highly mar resistant coatings.NOTE1The mar resistance values obtained by these test methods haveno absolute significance.They should
