Tests to be carried out for conduit systems
complying with EN 50086-1:1993

This annex contains the following additional tests which are necessary to be carried out on conduit
systems already complying with EN 50086-1:1993 in order for them to be declared to meet the
requirements of EN 61386–1:2003.

10.3 Impact test
NOTE The test has to be carried out because the compliance after the test has to be checked with a gauge.

13.1.3.2 Test with 1kW flame
NOTE The test has to be carried out because the combustion has been expanded to include flaming or glowing.

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.

CONDUIT SYSTEMS FOR ELECTRICAL INSTALLATIONS –
Part 1: General requirements
1 Scope
This part of IEC 1386 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 1000 V a.c. and/or 1500 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 670.
NOTES
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.
2 Earthing conductors may or may not be insulated.
