If smaller tolerances are needed or bigger are more economical these tolerances should be mentioned directly according to ISO 1101. The limit measurements of the tolerance classes m and f of DIN ISO 2768-1 are identic with those of DIN 7168-1.ĭIN ISO 2768-2 is for simplifying drawing and fixes general tolerances in three tolerance classes for form and position.īy choosing a special tolerance class exactly the precision level common in workshops should be taken into account. ISO 2768 – m or general tolerance ISO 2768 – mįor new designs only the general tolerance according to DIN ISO 2768-1 should be valid. The following has to be inserted in the title box, i.e. If general tolerances according to ISO 2768-1 are valid, Tabelle 3 Grenzabmasse für Winkelmasse Tolerance classįor nominal sizes below 0,5 mm the limit measures are to be indicated directly at the nominal measure.
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.
