Geometrical product specifications (GPS) - Geometrical tolerancing - Pattern and combined geometrical specification

This document establishes complementary rules to ISO 1101 to be applied to pattern specifications and defines rules to combine individual specifications, for geometrical specifications e.g. using the symbols POSITION, SYMMETRY, LINE PROFILE and SURFACE PROFILE, as well as STRAIGHTNESS (in the case where the toleranced features are nominally coaxial) and FLATNESS (in the case where the toleranced features are nominally coplanar) as listed in Annex C.These rules apply when a set of tolerance zones are grouped together with location or orientation constraints, through the use of the CZ, CZR or SIM modifiers.This document does not cover the use of the pattern specifications when the least and maximum material requirement is applied (see ISO 2692).This document does not cover the establishment of common datum (see ISO 5459) based on pattern features.

La présente Norme internationale décrit le tolérancement de localisation. Cette méthode de tolérancement s'applique à la position d'un point, d'une ligne nominalement droite ou d'une surface nominalement plane, par exemple le centre d'une sphère, l'axe d'un alésage ou d'un arbre, la surface médiane d'une rainure. NOTE Le tolérancement de profil est utilisé dans le cas de lignes nominalement non rectilignes ou de surfaces nominalement non planes, voir l'ISO 1660.

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.
