Geometrical product specifications (GPS) - Features utilized in specification and verification (ISO 22432:2011)
ISO 22432:2011 defines general terms and types of features for geometrical features of specifications for workpieces. These definitions are based on concepts developed in ISO/TS 17450-1.
ISO 22432:2011 is not intended for industrial use as such among designers, but is aimed to serve as the "road map" mapping out the interrelationship between geometrical features, thus enabling future standardization for industry and software makers in a consistent manner.
Geometrische Produktspezifikation (GPS) - Zur Spezifikation und Prüfung benutzte Geometrieelemente (ISO 22432:2011)
Diese Internationale Norm legt die allgemeinen Begriffe und Merkmalstypen von (Geometrie) Elementen zur
technischen Beschreibung von Werkstücken fest. Diese Festlegungen beruhen auf den in der Norm
ISO/TS 17450-1 entwickelten Konzepten.
Es war nicht die Absicht, dass diese Internationale Norm als solche für die industrielle Anwendung unter
Konstrukteuren verwendet wird, sondern sie zielt vielmehr darauf ab, als ein Leitfaden zu dienen, der die
gegenseitige Beziehung zwischen (Geometrie) Elementen abbildet, um damit eine zukünftige
Standardisierung für die Industrie und für Programmierer in einer folgerichtigen Art und Weise zu ermöglichen.
Spécification géométrique des produits (GPS) - Éléments utilisés en spécification et vérification (ISO 22432:2011)
L'ISO 22432:2011 définit les termes généraux et les types d'éléments pour les éléments géométriques des spécifications des pièces. Ces définitions s'appuient sur les concepts développés dans l'ISO/TS 17450‑1.
L'ISO 22432:2011 n'est pas destinée, en tant que telle, à un usage industriel par les concepteurs, mais vise à servir de fil d'Ariane pour l'élaboration des relations entre les éléments géométriques, permettant ainsi la future normalisation pour l'industrie et les concepteurs de logiciels de manière cohérente.
Specifikacija geometrijskih veličin izdelka - Značilnosti, potrebne za geometrijsko specifikacijo in preverjanje (ISO 22432:2011)
Ta mednarodni standard definira splošne izraze in vrste značilnosti za geometrijske značilnosti specifikacij za obdelovance. Te definicije temeljijo na konceptih, razvitih v ISO/TS 17450-1. Ta mednarodni standard naj se uporablja kot »zemljevid«, ki preslikuje medsebojne povezave med geometrijskimi značilnostmi in s tem dosledno omogoča prihodnjo standardizacijo za industrijo in izdelovalce programske opreme.

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 22432 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product

Introduction
This International Standard is a Geometrical Product Specifications (GPS) standard and is to be regarded as
a global GPS standard (see ISO/TR 14638). It influences all chain links in all chains of standards in the
general GPS matrix.
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.
Geometrical features exist in three “worlds”:
the world of nominal definition, where an ideal representation of the workpiece is defined by the designer;
the world of specification, where the designer has in mind several representations of the workpiece;
the world of verification, where one (or more) representation(s) of a given workpiece is (are) identified in
the application of measuring procedure(s).
In the world of verification, mathematical operations can be distinguished from physical operations. The
physical operations are the operations based on physical procedures; they are generally mechanical, optical
or electromagnetic. The mathematical operations are mathematical treatments of the sampling of the
workpiece. This treatment is generally achieved by computing or electronic treatment.
It is important to understand the relationship between these three worlds. This International Standard defines
standardized terminology for geometrical features principally in the world of specification and the world of
verification, to be used in communication between each world.
The features defined in this International Standard are well suited for the specification of rigid parts and
assemblies, and may also be applied to non-rigid parts and assemblies by specifying allowable variation
according to rigid solids.

specification and verification
1 Scope
This International Standard defines general terms and types of features for geometrical features of
specifications for workpieces. These definitions are based on concepts developed in ISO/TS 17450-1.
This International Standard aims to serve as the “road map” mapping out the interrelationship between
geometrical features, thus enabling future standardization for industry and software makers in a consistent
manner.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 14660-1, ISO/TS 17450-1 and
ISO/TS 17450-2 and the following apply.
3.1
surface model
model representing the set of features limiting the virtual or the real workpiece
NOTE 1 All closed surfaces (see Figures 1 and A.1) are included.
NOTE 2 The surface model allows the definition of single features, sets of features, and/or portions of features. The
total product is modelled by a set of surface models corresponding to each workpiece.

NOTE It is impossible to predict the total geometry of the real workpiece due to its geometrical imperfections. In this
International Standard, a real surface of the workpiece is illustrated in solid black.

3.1.1
nominal surface model
surface model of ideal geometry defined by the technical product documentation
NOTE 1 A nominal surface model is an ideal feature (See Figure 1 and Table 1).
NOTE 2 A nominal surface model is a continuous surface composed of an infinite number of points.
NOTE 3 Any feature on the nominal surface model (skin model) contains a continuous infinite number of points.
3.1.2
skin model
surface model of non-ideal geometry
NOTE 1 The skin model is a virtual model used to express the specification operator and the verification operator
considering a continuous surface (see Table 1 and ISO/TS 17450-1).
NOTE 2 A skin model is a non-ideal feature (see Figure 1).
NOTE 3 A skin model is a continuous surface consisting of an infinite number of points.
NOTE 4 Any feature on the skin model contains a continuous infinite number of points.
