This document 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 substrate or to an intermediate coat.
The method specified can be carried out
-
either as a “pass/fail” test, by testing with a single specified load applied to the stylus to assess conformity with a particular specification, or
-
as an assessment test by applying increasing loads to the stylus to determine the minimum load at which the coating is penetrated.
Neither this document nor ISO 1518-2 specifies a method using a curved stylus, which is specified in ISO 12137 . The choice between the three methods will depend on the particular practical problem.
