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.

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 URL: http:/// www .iso .org/ iso/

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

specifications and verification.

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 links F and G of the size chain of standards in the general

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

GPS matrix model, see Annex B.

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 specifications made in accordance with this

document, unless otherwise indicated.

The terms and concepts used in this document (compared to ISO/R 1938:1971) have been changed

according to needs and terminology in the other GPS standards.

This document deals with reference disk gauges. The use of reference disk gauges is explained in

Annex A.

NOTE The content of Table 2 uses the modifiers given in ISO 14405-1 and ISO 1101.
