ISO 1518:2011 specifies a test method for determining under defined conditions the resistance of a single coating or a multi-coat system of paint, varnish or related product to penetration by scratching with a scratch stylus loaded with a specified load. Penetration of the stylus is to the substrate, except in the case of a multi-coat system, in which case the stylus can penetrate either to the…
Paints and varnishes — Determination of scratch resistance — Part 1: Method using a curved stylus
ISO 12137-1:2010 specifies a method for determining, using a curved (loop-shaped or ring-shaped) 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…
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…
