General tolerances - Part 2: Geometrical tolerances for features without individual tolerance indications Executive summary General geometrical tolerances to control features on drawings without individual tolerance indications. Abstract This part of EN 22768 is intended to simplify drawing indications and specifies general geometrical tolerances to control those features on drawings which have no respective individual indication. It specifies general geometrical tolerances in three tolerance classes. This European Standard mainly applies to features which are produced by removal of material. Its application to features manufactured by other processes is possible; however, special examination is required to ascertain whether the customary workshop accuracy lies within the general geometrical tolerances specifications. History and related standards This European Standard includes the following cross references: ISO 1101:1983, ISO 2768-1:1989, ISO 5459:1981, ISO 8015:1985.
