Tolerance Chart — Iso 2768-mh

Many engineers misread the chart because they forget the scaling rule for geometric tolerances. Let’s walk through three real-world scenarios.

When you see on a technical drawing, it means that unless otherwise specified, the workshop must adhere to the Medium linear tolerances and High (h) geometric tolerances listed above. This approach reduces drafting time and clarifies which dimensions are critical versus standard. iso 2768-mh tolerance chart
