Book excerpt: This document describes the principle, instrument and equipment, specimens, test procedures and test report of the test method for surface roughness of carbon materials. This document is applicable to the evaluation of surface roughness of carbon material products with aggregate particles less than 1.6 mm through the stylus profile method. Generally, the arithmetical mean deviation of profile (Ra) is selected as the measurement parameter, and other parameters, for example, maximum height of profile (Rz), can also be selected as needed. Other carbon materials may take this as a reference.
