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.

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.

– 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,
