Cette deuxième édition annule et remplace la première édition publiée en 1996 et son Amendement 1 (2000), et constitue une révision technique. Les modifications par rapport à la première édition sont les suivantes: - modification de la longueur de l'échantillon d'essai entre accessoires pour l'essai de traction, - mises à jour éditoriales et des références normatives.

Sistemi kanalov za električne inštalacije - 1. del: Splošne zahteve (IEC 61386-1:2008)

Ta del standarda IEC 61386 določa zahteve in preskuse za sisteme kanalov, vključno s kanali in nastavki za kanale, za zaščito in upravljanje izoliranih vodnikov in/ali kablov pri električnih inštalacijah ali komunikacijskih sistemih do 1000 V AC in/ali 1500 V DC. Ta standard se uporablja za kovinske, nekovinske in kompozitne sisteme kanalov, vključno z navojnimi in nenavojnimi vhodi, ki zaključujejo sistem. Ta standard se ne uporablja za ohišja in priključne doze v okviru standarda IEC 60670.

CONDUIT SYSTEMS FOR CABLE MANAGEMENT –
Part 1: General requirements
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 61386-1 has been prepared by subcommittee 23A: Cable
management systems, of IEC technical committee 23: Electrical accessories.

This second edition cancels and replaces the first edition published in 1996, and its

Amendment 1 (2000), and it constitutes a technical revision. The changes to the first edition

are as follows:

– change to the length of the test specimen between fittings for the tensile test,

– editorial and normative reference updates.

The text of this standard is based on the following documents:
FDIS Report on voting
23A/553/FDIS 23A/558/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.

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

A list of all the parts in the IEC 61386 series, under the general title Conduit systems for cable

management, can be found on the IEC website.

This Part 1 is to be used in conjunction with the appropriate Part 2, which contains clauses to

supplement or modify the corresponding clauses in Part 1, to provide the relevant particular

requirements for each type of product. A conduit system which conforms to this standard is

deemed safe for use.
In this publication, the following print types are used:
– Requirements proper: in roman type.
– Test specifications: in italic type.
Explanatory matter: in smaller roman type.
The following differences exist in some countries:

6.5.2: In Australia and Austria, conduits and conduit fittings may be classified with low acid

gas emission.

13.1.4: In Australia conduits and conduit fittings classified as low acid gas emission shall be

tested in accordance with IEC 60754-1, evolve not more than the equivalent of 5 mg of

hydrochloride-acid per gram of sample.

In Austria conduits and conduit fittings classified as low acid gas emission shall be tested in

accordance with IEC 60754-2.

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

the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in

the data related to the specific publication. At this date, the publication will be

• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

CONDUIT SYSTEMS FOR CABLE MANAGEMENT –
Part 1: General requirements
1 Scope

This part of IEC 61386 specifies requirements and tests for conduit systems, including

conduits and conduit fittings, for the protection and management of insulated conductors

and/or cables in electrical installations or in communication systems up to 1 000 V a.c. and/or

1 500 V d.c. This standard applies to metallic, non-metallic and composite conduit systems,

including threaded and non-threaded entries which terminate the system. This standard does

not apply to enclosures and connecting boxes which come within the scope of IEC 60670.

NOTE 1 Certain conduit systems may also be suitable for use in hazardous atmospheres. Regard should then be

taken of the extra requirements necessary for equipment to be installed in such conditions.

NOTE 2 Earthing conductors may or may not be insulated.
