This European Standard was approved by CENELEC on 2003-09-23. CENELEC members are bound to

comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European

Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on

application to the Central Secretariat or to any CENELEC member.

language made by translation under the responsibility of a CENELEC member into its own language and

notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech

Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Foreword

The text of the International Standard IEC 61386-21:2002, prepared by SC 23A, Cable management

systems, of IEC TC 23, Electrical accessories, was submitted to the Unique Acceptance Procedure

and was approved by CENELEC as EN 61386-21 on 2003-09-23.

This European Standard supersedes EN 50086-2-1:1995 + corrigendum February 2001 + A11:1998 +

A11:1998/corrigendum February 2001.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-10-01
– latest date by which the national standards conflicting
(dow) 2008-06-30
with the EN have to be withdrawn

This part 21, which specifies particular requirements for rigid conduit systems, is to be used in

conjunction with EN 61386-1:2004.

This part 21 supplements or modifies the corresponding clauses of EN 61386-1. Where a particular

clause or subclause of part 1 is not mentioned in this part 21, that clause or subclause applies as far as

is reasonable. Where this part 21 states "addition", "modification" or "replacement", the relevant text of

part 1 is to be adapted accordingly.

Subclauses, tables and figures which are in addition to those in part 1 are numbered starting with 101.

Additional annexes are lettered AA, BB, etc.

A conduit system which complies with this standard is deemed safe for use when installed in accordance

with national wiring regulations, whilst applying the manufacturer's installation instructions and conduit

classification.
In this standard, the following print types are used:
- requirements: in roman type;
- test specifications: in italic type;
- notes: in smaller roman type.
Annexes ZAA and ZBB have been added by CENELEC.
The contents of the corrigendum of April 2004 have been included in this copy.

Special national conditions

Special national condition: National characteristic or practice that cannot be changed even over a

long period, e.g. climatic conditions, electrical earthing conditions.

NOTE If it affects harmonization, it forms part of the European Standard or Harmonization Document.

For the countries in which the relevant special national conditions apply these provisions are

normative, for other countries they are informative.

completely enclosed in suitable non-combustible building materials.

they are completely enclosed in suitable non-combustible building materials.

A-deviations

A-deviation: National deviation due to regulations, the alteration of which is for the time being outside

the competence of the CENELEC national member.
This European Standard falls under Directive 73/23/EEC.

NOTE (from CEN/CENELEC IR Part 2, 2.17) Where standards fall under EC Directives, it is the view of the Commission of the

European Communities (OJ No C 59, 1982-03-09) that the effect of the decision of the Court of Justice in Case 815/79

Cremonini/Vrankovich (European Court Reports 1980, p. 3583) is that compliance with A-deviations is no longer mandatory and

that the free movement of products complying with such a standard should not be restricted within the EC except under the

safeguard procedure provided for in the relevant Directive.

A-deviations in an EFTA-country are valid instead of the relevant provisions of the European

Standard in that country until they have been removed.

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

organi
