Geometrical product specifications (GPS) - Characteristics and conditions - Definitions (ISO 25378:2011)
ISO 25378:2011 defines general terms for geometrical specifications, characteristics and conditions. These definitions are based on concepts developed in ISO 17450-1 and ISO 22432 and they are given by using a mathematical description based on Annex B of ISO 17450-1:2011.
ISO 25378:2011 is not intended for industrial use as such among designers, but is aimed to serve as the "road map" mapping out the requirements based on geometrical features, thus enabling future standardization for industry and software makers in a consistent manner.
ISO 25378:2011 defines general types of geometrical characteristics and conditions which can be used in GPS. These descriptions are applicable to
a workpiece,
an assembly,
a population of workpieces, and
a population of assemblies.
These definitions are based on concepts of operators and the duality principle contained in ISO 17450-1 and ISO/TS 17450-2 and on the description of types of geometrical features defined in ISO 22432.
Conceptually, these specification operators can be used as specification operators or as verification operators (duality principle).
ISO 25378:2011 is not intended to define GPS specifications, symbology or other types of expression.
Geometrische Produktspezifikation (GPS) - Merkmale und Bedingungen - Begriffe (ISO 25378:2011)
Diese Internationale Norm legt die allgemeinen Begriffe für die geometrischen Spezifikationen, Merkmale und
Bedingungen fest. Diese Definitionen beruhen auf Konzepten, die in ISO 17450-1 und ISO 22432 entwickelt
wurden und sie werden unter Verwendung einer mathematischen Beschreibung angegeben, die auf dem
Anhang B von ISO 17450-1:2011 beruht.
Diese Internationale Norm als solche ist nicht für den industriellen Einsatz unter Konstrukteuren gedacht,
sondern zielt darauf ab, als „Road-Map“ für die Beschreibung der auf Geometrieelementen beruhenden
Anforderungen zu dienen, um so eine zukünftige Normung für die Industrie und die Software-Hersteller in
einer konsistenten Art und Weise zu ermöglichen.
Diese Internationale Norm legt allgemeine Arten von geometrischen Merkmalen und Bedingungen fest, die in
der geometrischen Produktspezifikation verwendet werden können. Diese Beschreibungen sind anwendbar
für
⎯ ein Werkstück,
⎯ eine Baugruppe,
⎯ eine Grundgesamtheit von Werkstücken und
⎯ eine Grundgesamtheit von Baugruppen.
Diese Definitionen beruhen auf den Konzepten von Operatoren und dem in ISO 17450-1 und ISO/TS 17450-2
enthaltenen Dualitätsprinzip, sowie auf der Beschreibung der Arten von Geometrieelementen, die in
ISO 22432 festgelegt sind.
Konzeptionell können diese Spezifikationsoperatoren als Spezifikationsoperatoren oder als
Verifikationsoperatoren verwendet werden (Dualitätsprinzip).
Diese Internationale Norm beabsichtigt nicht, GPS-Spezifikationen, Symbolik oder andere Formen des
Ausdrucks festzulegen
Spécification géométrique des produits - Caractéristiques et conditions - Définitions (ISO 25378:2011)
L'ISO 25378:2011 définit les termes généraux relatifs aux spécifications, caractéristiques et conditions géométriques. Ces définitions reposent sur des concepts développés dans l'ISO 17450‑1 et l'ISO 22432. Elles sont accompagnées d'une description mathématique basée sur l'Annexe B de l'ISO 17450‑1:2011.
L'ISO 25378:2011 n'est pas destinée à un usage industriel en l'état par les concepteurs. Elle fait office de «carte routière» mettant en évidence les exigences reposant sur les fonctions géométriques, permettant ainsi de concevoir de manière cohérente une future normalisation destinée aux industriels et aux fabricants de logiciels.
L'ISO 25378:2011 définit les types généraux de caractéristiques et conditions qui peuvent être utilisés en GPS. Ces descriptions sont applicables
à la pièce,
à un assemblage,
à une population de pièces, et
à une population d'assemblages.
Ces définitions s'appuient sur les concepts des opérateurs et du principe de dualité définis dans l'ISO 17450‑1 et l'ISO/TS 17450‑2 et sur les descriptions des éléments géométriques données dans l'ISO 22432.
De manière conceptuelle, ces opérateurs de spécification peuvent être utilisés comme des opérateurs de spécification ou des opérateurs de vérification (principe de dualité).
L'ISO 25378:2011 n'a pas pour but de définir les spécifications GPS, leurs symboles ou d'autres types d'expressions.
Specifikacija geometrijskih veličin izdelka - Značilnosti in razmere - Definicije (ISO 25378:2011)
Ta mednarodni standard opredeljuje splošno terminologijo za geometrijske specifikacije, značilnosti in razmere.
Definicije so zasnovane na konceptih, razvitih v ISO 17450-1 in ISO 22432, in so podane z uporabo matematičnega opisa na osnovi dodatka B ISO 17450-1:2011.
Ta mednarodni standard kot tak ni namenjen industrijski uporabi pri načrtovalcih, pač pa naj se uporablja kot »zemljevid«, ki orisuje zahteve na osnovi geometrijskih lastnosti, in s tem dosledno omogoča prihodnjo standardizacijo za industrijo in izdelovalce programske opreme.
Ta mednarodni standard opredeljuje splošne tipe geometrijskih značilnosti in razmer, ki se lahko uporabljajo pri GPS. Ti opisi veljajo za
⎯ izdelek,
⎯ sestav,
⎯ množico izdelkov in
⎯ množico sestavov.
Te definicije temeljijo na konceptih operatorjev in načelu dvojnosti iz ISO 17450-1 in ISO/TS 17450-2 ter na opisu tipov geometrijskih značilnosti, opredeljenih v ISO 22432.
Konceptualno se specifikacijski operatorji lahko uporabljajo kot specifikacijski operatorji ali kot overitveni operatorji (načelo dvojnosti).
Ta mednarodni standard ni namenjen opredelitvi specifikacij GPS, simbologije ali drugih vrst izražanja.

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.

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 of all chains of standards in the general
GPS matrix.
To facilitate the reading and the understanding of this International Standard, it is essential to refer to
ISO 17450-1 and ISO/TS 17450-2.
Geometrical characteristics exist in three “worlds”:
⎯ the world of nominal geometrical definition, where an ideal representation of the future workpiece is
defined by the designer;
⎯ the world of specification, where several representations of the future workpiece are imagined by the
designer;
⎯ the world of verification, where one or several representations of a given workpiece are identified in the
application of measuring procedure(s).
A GPS specification defines requirements through a geometrical characteristic and condition.
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.
These specifications, characteristics and conditions, generically defined in this International Standard, are well
suited to define requirements of rigid parts and assemblies and can also be applied to non-rigid parts and
assemblies.

as the “road map” mapping out the requirements based on geometrical features, thus enabling future
standardization for industry and software makers in a consistent manner.
This International Standard defines general types of geometrical characteristics and conditions which can be
