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.
Clause Special national condition
6.5.2 Finland (Finnish wiring rules SFS 6000-5-52:2002 (= HD 384.5.52 S1))
Flame propagating conduit systems are allowed to be used only if they are
completely enclosed in suitable non-combustible building materials.
United Kingdom (British wiring regulations BS7671: 2001 HD 384).
Flame propagating conduit systems are allowed to be used in buildings only if
they are completely enclosed in suitable non-combustible building materials.

Annex ZBB
(informative)
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
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 specifications, 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
