General Tolerances - Part 2: Geometrical Tolerances for Features without Individual Tolerance Indications
|Publication Date:||1 January 1989|
|ICS Code (Limits and fits):||17.040.10|
This part of ISO 2768 is intended to simplify drawing indications and specifies general geometrical tolerances to control those features on the drawing which have no respective individual indication. It specifies general geometrical tolerances in three tolerance classes.
This part of ISO 2768 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 specified in this part of ISO 2768.
