General Tolerances for Linear and Angular Dimensions According to ISO 2768-mH: Interpretation, Application, and Industrial Implications
For features with a nominal size (width) up to 100 mm → 0.2 mm; up to 300 mm → 0.3 mm; up to 1000 mm → 0.5 mm. iso 2768 m h
For class m, deviation = ±0.2 mm for nominal sizes 0.5–3 mm, and ±0.5 mm for >3–120 mm. 3.2 Geometrical Tolerances (Part 2 – Class "H") Class H is the fine category for geometrical features such as straightness, flatness, perpendicularity, symmetry, and runout. Table 2 lists permissible deviations for the relevant nominal size ranges of the feature’s longer dimension. Table 2 lists permissible deviations for the relevant
For class m, the deviation is ±0.5° or ±30 minutes for nominal lengths ≤120 mm, and ±0°20' per 100 mm length for larger features. and ±0.5 mm for >
