This part of ISO 1518 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
a) either as a “pass/fail” test, by testing with a single specified load applied to the stylus to assess
compliance with a particular specification;
b) or by applying increasing loads to the stylus to determine the minimum load at which the coating is
penetrated.
