Scope

This document specifies a test method for assessing the resistance of paint
coatings and varnishes (including wood stains) to separation from substrates
when a right-angle lattice pattern is cut into the coating, penetrating through to
the substrate. The property determined by this empirical test procedure
depends, among other factors, on the adhesion of the coating to either the
preceding coat or the substrate. This procedure is not, however, a means of
measuring adhesion.
