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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

specifications and verification.

Introduction

This document is a geometrical product specifications (GPS) standard and is to be regarded as a

fundamental GPS standard (see ISO 14638). It influences all chain links of all chains of general GPS

standards (see Annex A for further information).

The ISO/GPS Matrix model given in ISO 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 this document apply in ISO/GPS, unless otherwise indicated.

Traditionally, functional requirements, manufacturing requirements and verification requirements

are mixed up in one and the same specification. Furthermore, the basic function of a part may be

jeopardized when changing the manufacturing and/or the verification process.

Consequently, the functional requirements may not be identified easily and, furthermore, traceability

to functional needs often gets obscured or impossible to derive.

Therefore, it is necessary to provide a structure to organize the mindset of the involved stakeholders

(such as designers, process engineers, verifiers, purchasers and suppliers). The design intent as

expressed in the functional specification is imperative and constitutes the master for all subsequent

specifications.
This document provides such a structure for documents with GPS, thus enabling:
— easier communication;
— clear distinction between the three basic types of specifications applied;
— improved contractual reliability.
