The following table provides an excerpt from the ISO 2768-MH tolerance chart for linear dimensions:
For example, if the nominal angle of a part is 45°, the tolerance value would be ±1.0°. iso 2768-mh tolerance chart
The "MH" in ISO 2768-MH refers to the specific tolerance class, which is defined as "medium" tolerance. This class provides a balance between the precision required for a part or component and the practical limitations of manufacturing processes. The following table provides an excerpt from the
For example, if the nominal dimension of a part is 50 mm, the tolerance value would be ±0.3 mm. For example, if the nominal dimension of a
| Nominal dimension (°) | Tolerance value (°) | | --- | --- | | 1 to 10 | ±0.5 | | 10 to 50 | ±1.0 | | 50 to 120 | ±2.0 |
The ISO 2768-MH tolerance chart provides a set of tables that list the tolerance values for different types of dimensions, including linear dimensions, angular dimensions, and geometric tolerances.
