The document describes the procedures for determining the resistance to cracking of an organic coating on a metallic substrate when bent through 135 ?to 180 ? The degree of adhesion may also be evaluated. Both folding and mandrel method are considered. The folding method is more often used for practical purposes but where more precise determinations are required, the mandrel method is recommended. The cylindrical bend method can also be used for a pass/fail decision by using an agreed mandrel.#,,#
