Part 1: Basic rules
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international co-operation on all questions concerning standardization in the electrical and electronic
fields. To this end and in addition to other activities, the IEC publishes International Standards. Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt
with may participate in this preparatory work. International, governmental and non-governmental organizations
liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the IEC on technical matters, express as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3)
The documents produced have the form of recommendations for international use and are published in the
form of standards, technical reports or guides and they are accepted by the National Committees in that
sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
5)
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the
subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 1346-1 has been prepared by subcommittee 3B: Documentation, of
IEC technical committee 3: Documentation and graphical symbols, and ISO technical
committee 10: Technical drawings, product definitions and related documentation. Formal
voting has taken place within IEC SC3B only. However, ISO TC10 has no objection to the
publishing of this International Standard.
This standard cancels and replaces IEC 750 published in 1983.
The text of this standard is based on the following documents:
FDIS Report on voting
3B/144/FDIS 3B/159/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
IEC 1346 consists of the following parts under the general title: Structuring principles and
reference designations:
- Part 1: Basic rules
- Part 2: Classification of objects and codes for classes (under consideration)
- Part 3: Application guidelines (under consideration)
- Part 4: Discussion of some concepts used in the reference designation system

INTRODUCTION
In connection with the design, engineering, realization, operation, maintenance and demolition, i.e. the
life-cycle of a system, it is necessary to employ a number of identification systems for different purposes,
for example:
- product (article) numbering system used for identification of types of products;
serial number system used for identification of product individuals;
order number system used for identification of orders/contracts;
-
- reference designation system used for identification of objects within a system/plant.
rt of IEC 1346 deals only with the reference designation system.
This pa
The following table relates the identification systems to theircontexts. The shaded areas show the context
of the reference designation system and the classification provided by the letter codes. The reference
designation system is also used in manufacturing or operating companies for identification of
occurrences of types.

1) Type: a class of objects having the same set of
2) Occurrence: the use of a type in a specific position in a plant or system.
3) Individual: one specimen of a type irrespective of where it is being used.
It should be noted that this standard provides a number of possibilities for the construction of reference
designations. For most applications, however, only a subset of the possibilities given need be used.
The basic requirements and the required properties of a reference designation system that form the basis
for the reference designation system described in this standard are given in annex A. It is recommended
to study this annex before reading the normative clauses of this standard. The annex contains a
description of the properties of the reference designation system of this standard in a comparison with the
required properties. A more comprehensive discussion of the basic concepts of the reference designation
system can be found in IEC 1346-4 [3]1.

AND INDUSTRIAL PRODUCTS -
STRUCTURING PRINCIPLES AND REFERENCE DESIGNATIONS -
Part 1: Basic rules
1 Scope
This part of IEC 1346 establishes general principles for describing the structure of information about
systems and of the systems themselves.
Based on these principles, rules and guidance are given for the formulation of unambiguous reference
designations for objects in any system.
The reference designation identifies objects for the purpose of correlating information about an object
among different kinds of documents and the products implementing the system. For manufacturing,
installation and maintenance purposes, the reference designation or pa rt of it may also be shown on or
near the physical part corresponding to the object.
The principles laid down are general and are intended to be applicable to all technical areas. They can be
used for systems based on different technologies or for systems combining several technologies.
2 Normative references
The following normative documents contain provisions, which through reference in this text, constitute
provisions of this pa rt of IEC 1346. At the time of publication, the editions indicated were valid. All
normative documents are subject to revision, and pa rties to agreements based on this part of IEC 1346
are encouraged to investigate the possibility of applying the most recent editions of the normative
documents indicated below. Members of IEC and ISO maintain registers of currently valid normative
documents.

3 Definitions
of IEC 1346, the following definitions apply.
For the purposes of this pa rt
3.1 object: Entity treated in the process of design, engineering, realization, operation, maintenance
and demolition.
NOTES
1 The entity may refer to a physical or non-physical "thing", or to a set of information associated with it.
2 Depending on its purpose, an object may be viewed in different ways called "aspects" (see 3.3).
3.2 system:
Set of interrelated objects.
NOTES
1 Examples of a system: a drive system, a water supply system, a stereo system, a computer.
2 When a system is pa rt of another system, it may be considered as an object.
3.3 aspect: Specific way of selecting information on or describing a system or an object of a system.
NOTE - Such ways may be:
- what the system or object is doing (function viewpoint);
- how the system or object is constructed (product viewpoint);
- where the system or object is located (location viewpoint).
3.4 function: Purpose related to an object.
3.5 product: Intended or accomplished result of labour, or of a natural or artificial process.
NOTES
1 A product usually has a pa rt number, order number, type designation, and/or a name.
2 A technical system or plant can be considered as a product.
3.6 structure: Organization of relations among objects of a system describing constituency-relations
(consist of / is a pa rt of).
3.7 reference designation: Identifier of a specific object with respect to the system of which the object
is a constituent, based on one or more aspects of that system.
3.8 single-level reference designation: Reference designation assigned with respect to the object of
which the specific object is a direct constituent.
3.9 multi-level reference designation: Reference designation derived from a structural path through
an overall system.
Set of reference designations of which at least one un
