Norme Iso 2768 Mk !!link!! -

For angles, the tolerance depends on the length of the shorter leg of the angle. For Class "m":

| Nominal Dimension (mm) | Tolerance (mm) | | :--- | :--- | | 0.5 up to 3 | $\pm 0.1$ | | Over 3 up to 6 | $\pm 0.1$ | | Over 6 up to 30 | $\pm 0.2$ | | Over 30 up to 120 | $\pm 0.3$ | | Over 120 up to 400 | $\pm 0.5$ | | Over 400 up to 1000 | $\pm 0.8$ | | Over 1000 up to 2000 | $\pm 1.2$ | norme iso 2768 mk

The tolerance value depends on the nominal dimension range. Below is an extract from the ISO 2768-1 table for Class "m": For angles, the tolerance depends on the length
