GB/T 42671-2023 "Test Method for Surface Roughness of Carbon Materials" specifies the test methods for the surface roughness of carbon materials (such as graphite electrodes, carbon bricks). It uses stylus-type roughness testers to measure parameters such as the arithmetic mean deviation of the profile (Ra) and the ten-point height of irregularities (Rz) to evaluate the surface processing quality of the materials.
