Scope

This standard specifies a method for determining the scratch resistance of a single layer or a composite coating of paint, varnish, or related products using an arc-shaped (ring-shaped or circular-ring-shaped) scratch tester. It has been proven that this method is effective for comparing the scratch resistance of different coatings, and it is very useful for determining the relative rankings of a series of painted panels that show significant differences in scratch resistance. This standard does not specify the use of a sharp-tipped scratch tester, which is specified in ISO 15181 and ISO 15182. The choice of these three methods will depend on specific practical circumstances.
