[Current]Paints and related materials — Methods of test, Method 408.2: Adhesion — Knife test
This Standard method sets out two procedures for assessing qualitatively the adhesion of a coating or coating system of any thickness, to a metal substrate by cutting through the coating in a prescribed manner. This method may be used on other substrates but has limitations on soft friable substrates.
