Technical drawings. Dimensioning and tolerancing. Datums and datum-systems for geometrical tolerances.

Les tolérances géométriques d'orientation, de position et de battement (et certaines tolérances de forme) se rapportent à une référence spécifiée. Le but de la présente norme est d'indiquer la façon dont on identifie une référence sur un dessin ; elle précise également la signification des différentes spécifications de références. Pour l'établissement des références au moment du contrôle, voir la norme expérimentale E 10-105.

Geometrical product specifications (GPS) - Geometrical tolerancing - Datums and datum systems

This document specifies terminology, rules and methodology for the indication and understanding of datums and datum systems in technical product documentation. This document also provides explanations to assist the user in understanding the concepts involved. This document defines the specification operator (see ISO 17450-2) used to establish a datum or datum system. The verification operator (see ISO 17450-2) can take different forms (physically or mathematically) and is not the subject of this document. NOTE            The detailed rules for maximum and least material requirements for datums are given in ISO 2692.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
