For example, if the nominal dimension of a part is 50 mm, the tolerance value would be ±0.3 mm.
The following table provides an excerpt from the ISO 2768-MH tolerance chart for linear dimensions:
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. iso 2768-mh tolerance chart
| Nominal dimension (mm) | Tolerance value (mm) | | --- | --- | | 6 to 30 | ±0.2 | | 30 to 120 | ±0.3 | | 120 to 400 | ±0.5 | | 400 to 1000 | ±0.8 |
Whether you are working in the engineering, manufacturing, or construction industry, the ISO 2768-MH tolerance chart is an essential tool to have in your toolkit. By following the guidelines outlined in this article, you can ensure that your parts and components meet the required tolerances, reducing the risk of defects and improving overall quality. For example, if the nominal dimension of a
For example, if the nominal angle of a part is 45°, the tolerance value would be ±1.0°.
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. | Nominal dimension (mm) | Tolerance value (mm)
The ISO 2768-MH tolerance chart is a part of the ISO 2768 standard, which was first published in 1989 by the International Organization for Standardization (ISO). The standard provides general tolerances for linear and angular dimensions, and it is widely used in various industries, including engineering, manufacturing, and construction.
