Industrial systems, installations and equipment and industrial products - Structuring principles and reference designations - Part 1: Basic rules (IEC 81346-1:2009)

This part of IEC 81346, published jointly by IEC and ISO, establishes general principles for the structuring of systems including structuring of the information about systems. 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 creation and retrieval of information about an object, and where realized about its corresponding component. A reference designation labelled at a component is the key to find information about that object among different kinds of documents. The principles are general and are applicable to all technical areas (for example mechanical engineering, electrical engineering, construction engineering, process engineering). They can be used for systems based on different technologies or for systems combining several technologies.

Systèmes industriels, installations et appareils, et produits industriels - Principes de structuration et désignations de référence - Partie 1: Règles de base (CEI 81346-1:2009)

La CEI 81346-1:2009 publié conjointement par la CEI et l'ISO établit les principes généraux pour la structuration des systèmes y compris la structuration des informations sur ces systèmes. Sur la base de ces principes, des règles et des lignes directrices sont données pour la formulation de désignations de référence non ambiguës applicables aux objets d'un système quel qu'il soit. La désignation de référence identifie des objets afin de la création et de la récupération d'informations sur un objet, et où réalisé au sujet de son composant correspondant. Cette édition inclut par rapport à la précédente les modifications techniques majeures suivantes: - un nouvel article d'introduction donnant une description et une explication des concepts utilisés dans le cadre de la présente publication; - une description plus complète des principes et des règles de structuration; - l'introduction d''autres aspects' auxquels on assigne le signe # comme préfixe; - la suppression du concept de groupe de désignations de référence; - le terme spécifique 'transition' a été évité et remplacé par une description textuelle améliorée de ce phénomène en annexe D; - l'introduction d'un nouvel article concernant l'étiquetage, - le retrait des anciennes annexes à l'exception de celle qui représente un exemple de l'application des désignations de référence au sein d'un système; - l'introduction d'une nouvelle annexe expliquant la manipulation des objets; - l'introduction de 4 nouvelles annexes correspondant à une réorganisation des exemples détaillés ou des explications.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). 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. 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 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 IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 81346-1 has been prepared by IEC technical committee 3:

Information structures, documentation and graphical symbols, in close co-operation with ISO

technical committee 10: Technical product documentation.
It is published as a double logo standard.

This edition cancels and replaces the first edition of IEC 61346-1, published in 1996. This

edition constitutes a technical revision.

This edition includes the following substantial changes with respect to the first edition of

IEC 61346-1:

– a new introductory clause providing a description and explanation to the concepts used

elsewhere in the publication;

– a more comprehensive description of the structuring principles and rules for structuring

are provided;
---------------------- Page: 12 ----------------------

– “other aspects” are introduced, and the prefix sign # is assigned to these aspects;

– the concept of reference designation group has been deleted;

– the specific term “transition” has been avoided and been replaced by an improved textual

description of this phenomenon in annex D;
– a new clause about labelling is introduced;

– the old annexes have been removed with the exception of the annex showing an example

of the application of reference designations within a system;
– a new annex explaining the manipulation of objects is introduced;

– 4 new annexes are introduced as rearrangement of detailed examples or explanatory

information.
The text of this standard is based on the following documents:
FDIS Report on voting
3/947/FDIS 3/958/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. In ISO, the standard has been approved by 12 members

out of 13 having cast a vote.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts of the International Standard 81346 series, formerly IEC 61346 series, under

the general title Industrial systems, installations and equipment and industrial products –

structuring principles and reference designations, can be found on the IEC website.

Future standards in this series will carry the new general number 81346. Numbers of existing

standards in this series will be updated at the time of the next edition.

The committee has decided that the contents of this publication will remain unchanged until

the maintenance
