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.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.
