ISO 25178-72:2017/Amd 1:2020 is part of the ISO 25178 standard series, which deals with areal surface texture. "Areal surface texture" refers to the imperfections or variations in the surface of an object. Specifically, this standard, along with its amendment, focuses on the graphical symbols used to indicate areal surface texture requirements on technical product documentation. It defines how these symbols are composed, where they are placed, and what information they convey about the required surface finish.
