CONDUIT SYSTEMS FOR ELECTRICAL INSTALLATIONS –
Part 1: General requirements
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.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
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. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 1386-1 has been prepared by subcommittee 23A: Cable
management systems, of IEC technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23A/260/FDIS 23A/274/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 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.
Annex A is an integral part of this standard.

4 General requirements
4.1 Conduit and conduit fittings within the scope of this standard shall be so designed and
constructed that in normal use their performance is reliable and without danger to the user or
surroundings.
When assembled in accordance with manufacturer’s instructions as part of a conduit system,
conduits and conduit fittings shall provide mechanical and, where required, electrical protection
of the insulated conductors and cables contained therein.
4.2 The protective properties of the joint between the conduit and conduit fitting shall not be
less than that declared for the conduit system.
4.3 Conduit and conduit fittings shall withstand the stresses likely to occur during transport,
storage, recommended installation practice and application.
4.4 In general, compliance is checked by carrying out all the tests specified.
5 General conditions for tests
5.1 Tests in accordance with this standard are type tests.
5.2 Unless otherwise specified, the tests shall be carried out at an ambient temperature of
o
(23 ± 2) C.
---------------------- Page: 11 ----------------------
1386-1 IEC:1996 – 13 –
5.3 Unless otherwise specified, each test shall be made on three new samples.
NOTE – Certain tests, for instance the checking of dimensions, do not affect a change in the property of the
samples; therefore these samples are considered as new samples and can be used for further tests.
5.4 Samples of non-metallic and composite conduits and conduit fittings shall be conditioned
o
for at least 240 h, at a temperature of (23 ± 2) C and a relative humidity between 40 % and
60 %. All tests shall be carried out immediately after general conditioning.
5.5 Unless otherwise specified, the samples for each test shall be in a clean and new
condition, with all parts in place and mounted as in normal use. After checking dimensions in
accordance with clause 8, and unless otherwise specified in the relevant test, the conduit
fittings shall be assembled with adequate lengths of conduit of the type for which they are
intended. Due regard shall be taken of the manufacturer’s instructions, especially where force
is required in the assembly of the joint.
NOTE – Where similarities are claimed, the selection of representative fittings for test purposes can be agreed
between the manufacturer, or responsible vendor, and the testing station.
5.6 Where the conduit entries are part of the detachable or loose type conduit fitting, the
detachable conduit fitting shall be capable of being assembled again, after the test, according
to the manufacturer’s instructions without loss of the declared properties according to clause 6.
5.7 Unless otherwise specified, three samples are submitted to the tests, and the
requirements are satisfied if the tests are met.
If only one of the samples does not satisfy a test, due to an assembly or a manufacturing
defect, that test and any preceding one which may have influenced the result of the test shall
be repeated, and also the tests which follow shall be made in the required sequence on another
full set of samples, all of which shall comply with the requirements.
NOTE – If the additional set of samples is not submitted at the same time, a failure of one sample will entail a
rejection. The applicant, when submitting the first set of samples, may also submit an additional set of samples
which may be used, should one sample fail. The testing station will then, without further request, test the
additional set of samples and will reject them only if a further failure occurs.
5.8 When toxic or hazardous processes are used, due regard shall be taken of the safety of
the persons within the test area.
5.9 Conduit systems which are used as an integral part of other equipment shall also be
tested in accordance with the relevant standard for that equipment.
