The standard is the third part of the metal surface roughness comparison sample, which specifies the manufacturing method, surface characteristics and related technical requirements for the comparison sample used to evaluate the mass of the metal surface processing. The standard aims to provide a uniform reference standard to help in the field of mechanical manufacturing, metal processing, etc., by visual or tactile comparison of the sample, accurately assess the asperity level of the workpiece surface, to ensure that the product meets the design and process requirements.
