IEC 61084-2-2:2017

Cable trunking systems and cable ducting systems for electrical installations - Part 2-2: Particular requirements - Cable trunking systems and cable ducting systems intended for mounting underfloor, flushfloor, or onfloor

IEC 61084-2-2:2017 specifies requirements and tests for cable trunking systems (CTS) and cable ducting systems (CDS) intended for the accommodation, and where necessary for the electrically protective separation, of insulated conductors, cables and possibly other electrical equipment in electrical and/or communication systems installations. The maximum voltage of these installations is 1 000 V AC and 1 500 V DC.
These systems are intended for mounting underfloor, flushfloor or onfloor.
This document does not apply to CTS/CDS which are intended to be fixed to the wall and supported by the floor.
This document does not apply to conduit systems, cable tray systems, cable ladder systems, power track systems or equipment covered by other standards.
This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- classification;
- construction;
- mechanical and electrical properties.
This International standard is to be used in conjunction with IEC 61084-1:2017.

Systèmes de goulottes et systèmes de conduits-profilés pour installations électriques - Partie 2-2: Exigences particulières - Systèmes de goulottes et systèmes de conduits-profilés prévus pour être montés en sous-sol, encastrés dans le sol, ou sur le sol

IEC 61084-2-2:2017 spécifie les exigences et les essais pour les systèmes de goulottes (SG) et les systèmes de conduits-profilés (SCP) destinés au logement de conducteurs isolés, câbles et éventuels autres équipements électriques et, si nécessaire, à leur séparation de protection électrique, dans des installations électriques et/ou de systèmes de communication. La tension maximale de ces installations est de 1 000 V en courant alternatif et 1 500 V en courant continu.
Ces systèmes sont destinés à être montés sous le sol, encastrés dans le sol, ou sur le sol.
Le présent document ne s’applique pas aux SG/SCP prévus pour être fixés à un mur et soutenus par le sol.
Le présent document ne s’applique pas aux systèmes de conduits, systèmes de chemins de câble, systèmes d’échelles à câble, systèmes de canalisations préfabriquées ou aux équipements couverts par d’autres normes.
Cette deuxième édition annule et remplace la première édition parue en 2003. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- classification;
- construction;
- propriétés mécaniques et électriques.
Cette Norme internationale doit être utilisée conjointement avec l’IEC 61084-1:2017.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). 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. 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 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 IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
