Variations on dimensions without tolerance values are according to ' ISO 2768'. All tolerance limits are given in mm. ISO 2768 and derivative geometrical tolerance standards are intened to simplify drawing specifications for mechanical tolerances. ISO 2768 is mainly for parts that are manufactured by way of machniing or removeal of materials.

  • If general tolerances according to ISO 2768-1 are valid, the following has to be inserted in the title box, i.e. For tolerance class medium. ISO 2768 – m or general tolerance ISO 2768 – m. For new designs only the general tolerance according to DIN ISO 2768-1 should be valid.
  • Angular Dimension
  • External Radius and Chamfer height
  • Geometric Tolerance such as straightness, flatness, perpendicularity, symmetry and runout.
