Iso 2768-mh Tolerance Chart -
ISO 2768‑2 gives recommended tolerances for flatness, straightness, circularity, cylindricity, etc., corresponding to the same f/m/c/v classes. However, ISO 2768‑2 is limited and cannot replace proper GD&T where function requires control of form, orientation, runout, or position.
Based on the length of the shorter side. For sides up to 100mm, class h allows 0.2mm variance . iso 2768-mh tolerance chart
