The experiments for surface roughness of sheet metal with the DIN EN 10049 and GB/T2523 two test methods are compared, verified and explored according to the domestic and international production testing conditions of automobile leaf-spring. It is found that the stability and accuracy of gaussian filter are better than those of 2RC filter, stability of test data for sheet metal with different surface roughness ranges has no connection with the number of testing points as well as the surface roughness has no connection with plane grain trend through comparing the requirements of filter for testing surface roughness, number of test points for samples and test direction, which provide guidance for production testing with different standards.
