Geometrical product specifications (GPS) - General concepts - Part 1: Model for geometrical specification and verification (ISO 17450-1:2011)

ISO 17450-1:2011 provides a model for geometrical specification and verification and defines the corresponding concepts. It also explains the mathematical basis of the concepts associated with the model and defines general terms for geometrical features of workpieces.
ISO 17450-1:2011 defines the fundamental concepts for the GPS system in order to provide nonambiguous GPS language to be used in design, manufacturing and verification, to identify features, characteristics and rules to provide the basis for specifications, to provide a complete symbology language to indicate GPS specifications, to provide simplified symbology by defining default rules, and to provide consistent rules for verification.

Spécification géométrique des produits (GPS) - Concepts généraux - Partie 1: Modèle pour la spécification et la vérification géométriques (ISO 17450-1:2011)

L'ISO 17450-1:2011 propose un modèle pour la spécification et la vérification géométriques, et elle définit les concepts correspondants. Elle fournit également une explication des bases mathématiques de ces concepts associés aux modèles et définit les termes généraux utilisés pour les éléments géométriques des pièces.
L'ISO 17450-1:2011 définit les concepts fondamentaux du système GPS, afin de fournir un langage GPS non ambigu, destiné à être utilisé par la conception, la fabrication et le contrôle; d'identifier correctement les éléments, les caractéristiques et les règles permettant de fournir le fondement des spécifications; de fournir une symbolique complète permettant d'indiquer les spécifications GPS; de proposer une symbolique simplifiée pour exprimer des règles par défaut; et de développer des règles cohérentes pour la vérification.

ISO 17450-1:2011(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
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, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17450-1 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This first edition of ISO 17450-1 cancels and replaces ISO/TS 17450-1:2005, which has been technically
revised. It also incorporates the Technical Corrigendum ISO/TS 17450-1:2005/Cor.1:2007.
ISO 17450 consists of the following parts, under the general title Geometrical product specifications (GPS) —
General concepts:
 Part 1: Model for geometrical specification and verification
 Part 2: Basic tenets, specifications, operators, uncertainties and ambiguities

Introduction
This part of ISO 17450 is a geometrical product specification (GPS) document and is to be regarded as a
global GPS document (see ISO/TR 14638). It influences all chain links of the chains of standards.
The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this
document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the
default decision rules given in ISO 14253-1 apply to specifications made in accordance with this document,
unless otherwise indicated. For more detailed information on the relationship of this part of ISO 17450 to other
standards and to the GPS matrix model, see Annex F.
In a market environment of increased globalization, the exchange of technical product information is of high
importance and the need to express unambiguously the geometry of mechanical workpieces of vital urgency.
Consequently, codification associated with the macro- and micro-geometry of workpiece specifications needs
to be unambiguous and complete if the functional geometrical variation of pa
