1 Scope
This part of ISO 17450 defines terms related to specifications, operators (and operations) and uncertainties used in geometrical product specifications (GPS) standards. It presents the basic tenets of the GPS philosophy while discussing the impact of uncertainty on those tenets, and examines the processes of specification and verification as they apply to GPS.
Geometrische Produktspezifikation (GPS) - Grundlagen - Teil 2: Grundsätze, Spezifikationen, Operatoren, Unsicherheiten und Mehrdeutigkeiten (ISO 17450-2:2012)
Dieser Teil von ISO 17450-2 definiert Begriffe im Zusammenhang mit Spezifikationen, Operatoren (und Operationen) und Unsicherheiten, wie sie in den Normen der geometrischen Produktspezifikation (GPS) verwendet werden.

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 17450-2 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This first edition of ISO 17450-2 cancels and replaces ISO/TS 17450-2:2002, which has been technically
revised. It also incorporates ISO/TS 17450-2/Cor.1:2004.
ISO 17450 consists of the following parts, under the general title Geometrical product specifications (GPS) —

— Part 2: Basic tenets, specifications, operators, uncertainties and ambiguities

Introduction
This part of ISO 17450 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.
For more detailed information on the relationship of this part of ISO 17450 to other standards and to the GPS
matrix model, see Annex C.
This part of ISO 17450 covers several fundamental issues common to all the GPS standards developed by
ISO/TC 213 and, by presenting GPS’s basic tenets and specification and verification processes, explains some
of the underlying ideas and indicates the starting point for the standards developed by this technical committee.
It is pointed out that these ideas — and, for that matter, all the other ideas and concepts applied by ISO/TC 213
— are subject to development and refinement, as the TC’s recognition and understanding of them further
evolves during its ongoing standards work.

Geometrical product specifications (GPS) — General concepts —
Part 2:
Basic tenets, specifications, operators, uncertainties and
ambiguities
1 Scope
This part of ISO 17450 defines terms related to specifications, operators (and operations) and uncertainties
