General tolerances - Part 2: Geometrical tolerances for features without individual tolerance indications
出版：Japanese Standards Association
专家解读视频
This Japanese Industrial Standard 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 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 specified in this Standard.
