This part of ISO 2768 is intended to simplify drawing indica-tions and specifies general geometrical tolerances to control those features onThe drawing which have no respective in-dividual indication. It specifies general geometrical tolerances in three tolerance classes.This part of ISO 2768 mainly applies to features which are pro-duced by removal of material. Its application to features manufactured by other processes is possible; however, special examination is required to ascertain whetherThe customary workshop accuracy lies withinThe general geometrical toler-ances specified inThis part of ISO 2768.
