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.

Introduction

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

GPS standard (see ISO 14638). It influences the chain link A and B of the chain of standards on size and

location.

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 ISO 14253-1 apply to the specifications made in accordance with this

document, unless otherwise indicated.

For more detailed information of the relation of this document to other standards and the GPS matrix

model, see Annex B.

This document deals with general specifications. General specifications can be used to reduce the

number of individual specification indications in technical product documentation (TPD). Many

surfaces have individual requirements which are similar or identical. A single, general specification

may be applied to these instead of multiple individual specifications.

All figures in this document for the 2D drawing indications have been drawn in first-angle projection

with dimensions and tolerances in millimetres. It should be understood that third-angle projection

and other units of measurement could have been used equally well without prejudice to the principles

established.

The figures in this document represent either 2D drawing views or 3D axonometric views on 2D

drawings and are intended to illustrate how a specification can be fully indicated with visible

annotation. For possibilities of illustrating a specification where elements of the specification may be

available through a query function or other interrogation of information on the 3D CAD model and rules

for attaching specifications to 3D CAD models, see ISO 16792.
