General tolerances - Part 2: Geometrical tolerances for features without individual tolerance indications (ISO 2768-2:1989)

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.

Tolérances générales - Partie 2: Tolérances géométriques pour éléments non affectés de tolérances individuelles (ISO 2768-2:1989)

La présente partie de l'ISO 2768 vise à simplifier les indications devant figurer sur les dessins et prescrit les tolérances géométriques générales applicables aux éléments du dessin qui ne font pas l'objet d'un tolérancement individuel. Elle prescrit des tolérances géométriques générales regroupées en trois classes de tolérance. La présente partie de l'ISO 2768 est applicable principalement aux éléments exécutés par enlèvement de matière. Son application à des éléments obtenus par d'autres procédés de fabrication est possible ; néanmoins, cela nécessite un contrôle supplémentaire pour déterminer si la précision habituelle de l'atelier demeure dans les limites des tolérances géométriques générales prescrites dans la présente partie de l'ISO 2768.

IS0 2768-2 : 1989 (El Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 2768-2 was prepared by Technical Committee ISO/TC 3, Limits and fits. This first edition of IS0 2768-2, together with IS0 2768-l : 1989, cancel and replace IS0 2768 : 1973. IS0 2768 consists of the following parts, under the general title Genera/ tolerances: - Part tolerance for 7 : Tolerances indications linear and angular dimensions without individual - Part cations 2: Geometrical tolerances for features without individual tolerance indi- Annexes A and B of this part of IS0 2768 are for information only. 0 IS0 198s All rights reserved.

Iso 2768-2 : 1989 (El Introduction All 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 complete to ensure that the elements of size and geometry of all features are controlled, i.e. nothing shall be implied or left to judge- ment in the workshop or in the inspection department. The use of general tolerances this prerequisite is met. for size and geometry simplifies the task of ensuring that SIST EN 22768-2:2000

INTERNATIONAL STANDARD IS0 2768-2 : 1989 (El General tolerances - Part 2: Geometrical tolerances for features without individual tolerance indications 1 Scope This part of IS0 2768 is intended to simplify drawing indica- tions and specifies general geometrical tolerances to control those features on the drawing which have no respective in- dividual indication. It specifies general geometrical tolerances in three tolerance classes. This part of IS0 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 whether the customary workshop accuracy lies within the general geometrical toler- ances specified in this part of IS0 2768. 2 General When selecting the tolerance class, the respective customary workshop accuracy has to be taken into consideration, If smaller geometrical tolerances are required or larger geometrical tolerances are permissible and more economical for any individual feature, such tolerances should be indicated directly in accordance with IS0 1101 (see clause A.2).
