GB/T 42671-2023 "Test method for surface roughness of carbon materials"

This standard details the test method for evaluating the surface roughness of carbon products with aggregate particle size less than 1.6 mm using the stylus profile method. Measurement parameters are generally selected from the arithmetic average deviation (Ra) of the profile, and Miscellaneous parameters such as the maximum height of the profile (Rz) can be selected as required. The standard is suitable for determination at an initial temperature of not more than 200 ° C and an initial pressure of 1.0 MPa.
