The mandrel bend test is used to determine the ductility and adhesive strength of varnishes, paints or similar products on metallic substrates. In this test, the specimen is bent around a cylindrical (DIN EN ISO 1519) or conical (DIN EN ISO 6860) mandrel and is then examined for cracking or signs of delamination. The cylindrical mandrel bend test can be carried out with different bending radii in accordance with the specifications. In the conical mandrel bend test, the bending radius decreases along the longitudinal axis of the test specimen.
