Objective In order to meet the requirement both in raw materials selection of automobile steel plate and standardiza-tion of the incoming inspection & valuation, the surface roughness measuring standard characteristics in domestic and overseas fields were summarized, contrast testing with domestic and overseas labs was carried out, and an automobile steel plate surface roughness detecting & testing method was formulated via accumulating a large number of data. Methods Aiming at the actual re-quirement of steel plate surface roughness testing of automobile materials labs, a complete testing parameters setting and evaluation conditions selection details were designed, the chart with serial number, rolling direction labeling and specific testing location of a 100 mm × 100 mm square sample was formulated, in order to standardize the testing locations selection. The requirement of test sample preparation was proposed. The requirement of key testing procedures was presented, and a set of standardized operation programs convenient for applying in the testing site were formed. Results The surface structure of automobile textured cold rolled steel sheet led to little difference in the surface roughness measurement data when the sampling length was 0. 8 mm and 2. 5 mm, respectively. The surface roughness measurement data of hot rolled steel plate increased correspondingly along with the sampling length. Conclusion The method integrated with the ISO international standard, highlighted the site practical nature, and could be universally applied in surface roughness testing for automobile steel plate in automobile industry.
