Cable trunking systems and cable ducting systems for electrical installations - Part 2-4: Particular requirements for service poles and service posts
This European Standard 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 a.c. and 1 500 V d.c. Service poles and service posts are intended to be mounted in free space and in contact with mounting surface(s) only at one or two ends, where the word “mounted” means fixed or placed on the floor with a weighted base or linked to a mounting surface through a flexible component. NOTE Service poles and service posts can also be part of a CTS/CDS intended for wall or ceiling mounting covered by Part 2 1 or floor mounting covered by Part 2-2 and are then also tested according to Part 2-1 and/or Part 2-2 as appropriate. This European Standard does not apply to conduit systems, cable tray systems, cable ladder systems, powertrack systems or equipment covered by other standards. This European Standard shall be used in conjunction with EN 50085-1:2005 “Cable trunking systems and cable ducting systems for electrical installations – Part 1: General requirements” which is referred to in this document as Part 1.
Elektroinstallationskanalsysteme für elektrische Installationen - Teil 2-4: Besondere Anforderungen für freistehende Installationseinheiten
Diese Europäische Norm legt Anforderungen und Prüfungen für Elektroinstallationskanalsysteme, die für die Aufnahme und, wo erforderlich, für die Auseinanderhaltung oder Separierung von isolierten Leitern, Kabeln, Leitungen und möglichen anderen elektrischen Betriebsmitteln in elektrischen Installationen oder Kommunikationssystemen fest. Die maximale Spannung dieser Installationen ist 1 000 V Wechselspannung und 1 500 V Gleichspannung. Freistehende Installationseinheiten sind für die freistehende Montage und die Montage in Kontakt mit Montageflächen an einem oder an zwei Enden vorgesehen. Der Begriff Montage bedeutet befestigt oder mit einer beschwerten Basis auf dem Boden stehend oder mit einem flexiblen Bauteil an einer Montagefläche befestigt. ANMERKUNG Freistehende Installationseinheiten können Teil eines Elektroinstallationskanalsystems für Wand und Decke nach Teil 2-1 oder eines Elektroinstallationskanalsystems für Installationen unterflur, aufflur oder boden¬bündig nach Teil 2-2 sein. Diese Europäische Norm gilt nicht für Elektroinstallationsrohrsysteme, Kabelträgersysteme, Stromschienensysteme oder Einrichtungen, die von anderen Normen abgedeckt sind. Diese Europäische Norm muss zusammen mit EN 50085-1:2005 „Elektroinstallationskanalsysteme für elektrische Installationen – Teil 1: Allgemeine Anforderungen“ benutzt werden, auf welche in dieser Norm als Teil 1 Bezug genommen wird.
Systèmes de goulottes et systèmes de conduits-profilés pour installations électriques - Partie 2-4: Règles particulières pour les colonnes et colonnettes
La présente Norme Européenne spécifie les règles 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. Les colonnes et les colonnettes sont prévues pour être montées en espace libre et au contact de la ou des surfaces de montage uniquement à une extrémité ou aux deux extrémités, le mot "montées" signifiant fixées ou placées sur le sol avec une base lestée ou reliées à une surface de montage au moyen d'un composant flexible. NOTE Les colonnes / colonnettes peuvent aussi faire partie d'un SG/SCP prévu pour être monté au mur ou au plafond et relevant de la Partie 2-1, ou prévu pour être monté au sol et relevant de la Partie 2-2, et sont alors aussi soumises à essai selon la Partie 2-1 et/ou la Partie 2-2 selon le cas. La présente Norme Européenne ne s'applique pas aux systèmes de conduit, systèmes de chemin de câble, systèmes d'échelle à câble, systèmes de canalisation préfabriquée ou aux équipements couverts par d’autres normes. La présente Norme Européenne doit être utilisée conjointement avec la EN 50085-1:2005 "Systèmes de goulottes et de conduits-profilés pour installations électriques – Partie 1: Règles générales", à laquelle il est fait référence dans ce document comme Partie 1.

Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 213, Cable
management systems.
The text of the draft was submitted to the formal vote and was approved by CENELEC as
EN 50085-2-4 on 2009-05-01.

with the EN have to be withdrawn (dow) 2012-05-01
This European Standard is a system standard for cable management products used for electro-
1)
technical purposes. It relates to Low Voltage Directive 2006/95/EC through consideration of the
essential requirements of this directive.
This European Standard is supported by separate standards to which references are made.
This Part 2-4 is to be used in conjunction with EN 50085-1:2005 “Cable trunking systems and cable
ducting systems for electrical installations – Part 1: General requirements”.
This Part 2-4 supplements or modifies the corresponding clauses of EN 50085-1:2005. Where a
particular clause or subclause of Part 1 is not mentioned in this Part 2-4, that clause or subclause of
