Paints and varnishes — Determination of scratch resistance — Part 2: Method using a pointed stylus
ISO 12137-2:2010 specifies a method for determining, using a pointed stylus, the scratch 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 scratch resistance of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant…
