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 WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

specifications and verification.

Introduction
This Technical Specification is a geometrical product specification (GPS) document and is to be regarded
as a general GPS document (see ISO 14638). It influences chain links F of the chain of standards in the
general GPS matrix model.
For more detailed information of the relation of this Technical Specification to 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
Technical Specification is a part. The fundamental rules of ISO GPS given in ISO 8015 apply to this
Technical Specification. The default decision rules given in ISO 14253-1 apply to specifications made in
accordance with this Technical Specification, unless otherwise stated.
This Technical Specification gives guidance for the evaluation of the test value uncertainty as required
by the application of ISO 10360-5.
Before starting any test value uncertainty evaluation, it is recommended that
— the distinction between the test value uncertainty and the measurement uncertainty is fully
understood (the former is used to reduce the acceptance zone in a test, the latter to quantify the
reliability of a measurement value) and
— the principle of the tester’s responsibility in deciding whether or not to include an uncertainty
component in the budget is also understood.
Some details of the above issues are given in ISO/TS 23165, the careful reading of which is recommended.
