Part 2: Geometrical tolerances for features without individual tolerance indications It contains three tables and an informative annex with regard to concepts behind general tolerancing of dimensions.
This part is intended to simplify drawing indications and specifies general tolerances in three tolerance classes. It mainly applies to features which are produced by removal of material. It contains tour tables and an informative annex A with regard to concepts behind general tolerancing of dimensions, as well as an informative annex B with further information. IntroductionĪll features on component parts always have a size and a geometrical shape.
For the deviation of size and for the deviations of the geometrical characteristics (form, orientation and location) the function of the part requires limitations which, when exceeded, impair this function. The tolerancing on the drawing should be completed to ensure that the elements of size and geometry of all features are controlled, i.e.
