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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
This document is a technical product documentation (TPD) standard and is a complementary standard.
Modern computer-aided design (CAD) systems already provide built-in systems for the unambiguous
identification of each integral feature of a model. This identifier will often vary between CAD systems, but
typically comprises a long and complex code, which is normally difficult to read by humans and is therefore
impractical.
A datum feature identifier, indicated in a datum feature indicator on an integral feature of a part specified in
a TPD in accordance with ISO 5459, is a unique integral feature identifier. The name can be used to reference
that specific integral feature. However, all integral features of a part will not be indicated with a datum
feature identifier. This complicates the identification of integral features other than datum features.
Drawings are used in a variety of situations, e.g. design, manufacturing and verification (see ISO/TS 21619).
In many cases, it can be difficult to unambiguously communicate a reference to a specific integral feature,
either orally or in writing, in different documents when the part is not described in full detail in the drawing.
Depictions of the part are not always the most efficient way to communicate. Using a written identification
that unambiguously identifies each integral feature on the part
...
