The GB/T 31226-2014 standard specifies a method for analyzing the surface roughness of gas distribution system components using a scanning tunnel microscope (STM), which is suitable for measuring the surface roughness of stainless steel with Ra less than 0.25 µm. This method provides an accurate measurement method for surface quality control of specific materials, and is not suitable for steel surfaces with thick oxidation layers. The standard provides a technical basis for the evaluation of the surface roughness of gas distribution system components.
