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

Introduction
This document is a Technical Product Documentation (TPD) standard and it is a complementary
standard.
Modern 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 it 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 accordance with ISO 5459 on an integral feature of a part
defined in a TPD is a unique integral feature identifier, a unique label , which 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, which complicates the identification of other integral features than datum features.
Drawings are used in a variety of situations, e.g. design, manufacturing, and verification (see
ISO/TS 21619 Types of documents with GPS). 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 may be useful for the
following purposes: (the list is non-exhaustive)
— Ease verbal communication between stakeholders, e.g. between a customer and a supplier, or
between a designer and a manufacturer or a metrologist.
— Simplify the preparation of a nomenclature drawing of the part (human-readable naming of the
integral features).
— Ease the kinematic description of the part by stating what function an integral feature will have in
different product or part states, e.g. if it is a clearance or an interface surface.
— Referencing surfaces in documents, e.g.: standard operating procedures (SOPs), measurement
descriptions, measurement reports, non-conformities, customer complaint descriptions, failure
investigations, risk analyses, failure modes and effects analyses (FMEA), tolerance stack-up
calculations, change requests, etc.
Furthermore, unique identifiers of integral features can be used to simplify a TPD, e.g. when a special
requirement or subsequent machining, finishing or treatment shall apply to a group of different integral
features.
Human-readable identifiers for integral features are needed to ease the communication between
stakeholders and to clarify which integral feature a specification applies to, i.e. establish human-
understandable traceability, and to provide traceability between the drawing and other TPD. CAD
vendors are encouraged to implement a harmonised system of unique identifiers of integral features to
support the implementation of the benefits described in this introduction and in the standard.

Technical product documentation (TPD) — Unique integral
feature identification (UIFI)
1 Scope
This document defines how to uniquely identify the integral features of a part by an alpha-numerical
label and how indication in technical product documentation (TPD) is done, where needed to improve
human readability.
The proportions and dimensions of the graphical symbols for simplified indication of repeated features
are also specified.
