Tabular 2 Limit measures for radius of curvature and chamfer height Toleranceīei Nennmassen unter 0,5 mm sind die Grenzabmasse direkt am Nennmass anzugeben. Tabular 1 Limits for linear measures Tolerance-įor nominal sizes below 0,5 mm the limit measures are to be indicated directly at the nominal measure.

Then these tolerances are indicated next to the nominal size. If smaller tolerances are needed or bigger ones are more economical, General tolerances for linear measures and level squares with four tolerance classes are useful for simplifying drawings.īy choosing the tolerance class precision levels common in workshops should be taken into account.
