This standard specifies the method for measuring the surface roughness of steel after jet cleaning by the microscope focusing method, in particular calibrating ISO surface roughness comparison samples that meet the requirements of GB/T 13288.1. The standard applies to the determination of surface roughness of steel with an average peak-to-valley difference between 20 μm and 200 μm, and can also be used to evaluate the asperity of the surface of Miscellaneous abrasive spray-cleaned substrates. The standard provides a scientific Measuring method and calibrating basis for the evaluation of steel surface roughness after jet cleaning.
