: On a technical drawing, you would write: ISO 2768-mH (or commonly ISO 2768-mh )
For your workshop wall or CAD template, condense the ISO 2768-mh tolerance chart into this quick-reference table: iso 2768-mh tolerance chart
Do not write just "Tolerances: mH" without referencing ISO 2768. The standard implies specific rules for radii, chamfers, and how to treat zero values. : On a technical drawing, you would write:
Many engineers mistake "Coarse" for "low quality," but in ISO 2768, for typical welded fabrications or general machine parts where strict GD&T is not required. : On a technical drawing
