Abstract

A method and a device for determining a quality of a metallic surface of a metallic substrate, for example a steel or steel alloy substrate, are provided. The device includes a mould, a sheet holder and a die, with which the metallic substrate is formed to produce a drawn test surface. The method and device are used to test the quality of the metallic surface of a metallic coating with a view to a later utilization, especially with a view to a later forming, wherein the metallic substrate is formed at least in-an area of a test surface, wherein a main and an additional shape change of the metallic substrate in the area of the test surface assume predetermined values that are related to the later utilization of the metallic substrate, and wherein the quality of the metallic surface is tested on the test surface after forming.
