Scope
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.
The method may be used to compare the adhesion of paint films or to assess the change in adhesion of a coating after exposure, e.g., to natural weathering.
With appropriate modifications and by waiving the restraints of preconditioning and test conditions, the test is readily applicable to field use.
