Bend test in acc. with DIN EN ISO 1519

The mandrel bend test is used to determine the tensile strength and the adhesive strength of a coating consisting of paint, coating material or similar products on a metallic substrate by bending the test specimen around a cylindrical mandrel. The coating is then visually examined by means of a 10x magnifying glass to determine if the coating shows cracks or is detaching from the substrate. When examined with the naked eye, the coating must not show any cracking or flaking. According to the specifications, the mandrel bend test can be executed with different bending radii.
