"GB/T 13288.5-2009 Steel surface preparation before coating Coating Steel surface roughness characteristics after jet cleaning, Part 5: Determination method of surface roughness, replica strip method" specifies the method of measuring the surface roughness of steel after jet cleaning using the replica strip method. This method is suitable for metallic or Non-metallic abrasive spray cleaning surfaces. Fast and accurate measurement of surface roughness by special replica tape and measurement instrument can determine the average peak and valley height of 20 μm 115 μm asperity range. The standard is centralized by the China Shipbuilding Industry group company, issued on March 9, 2009, and officially implemented on November 1, 2009, providing an important on-site inspection basis for the steel surface preparation before painting.
