Paints and varnishes. Determination of mar resistance Ingestion-build-111333 Acknowledgement is given to the1 Scope This International Standard specifies a method for determining, using a curved (loop shaped or ring shaped) stylus, the mar resistance of a single coating of a paint, varnish or related product, or the upper layer of a multicoat system. This test has been found to be useful in comparing the mar resistance of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant differences in
