This European Standard was approved by CENELEC on 2006-12-01. 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.

This European Standard exists in three official versions (English, French, German). A version in any other
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, the Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 23A/513/FDIS, future edition 2 of IEC 61537, prepared by SC 23A, Cable
management systems, of IEC TC 23, Electrical accessories, was submitted to the IEC-CENELEC parallel
vote and was approved by CENELEC as EN 61537 on 2006-12-01.
This European Standard supersedes EN 61537:2001.
It incorporates additional tables, annexes and figures as well as revisions to such that appeared in
EN 61537:2001. In places, the text has been substantially altered including:
– the classification system,
– tests for resistance against corrosion,
– re-written SWL test procedure,
– re-written section on electrical non-conductivity.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2007-09-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2009-12-01
with the EN have to be withdrawn
Annexes ZA and ZB have been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 61537:2006 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60093 NOTE  Harmonized as HD 429 S1:1983 (not modified).
ISO 14713 NOTE  Harmonized as EN ISO 14713:1999 (not modified).

Annex ZB
(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 member.
This European Standard falls under Directive 73/23/EEC.
NOTE (from CEN/CENELEC IR Part 2:2006, 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 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.
Clause Deviation
6.2.1 France (Decree from Equipment and Accommodation Minister for low voltage installations
dated 22 October 1969)
Classification not allowed.
Annex C France (Decree from Equipment and Accommodation Minister for low voltage installations
dated 22 October 1969)
The use of cable tray systems and cable ladder systems as a PE conductor is not allowed.
