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.
When the standard is harmonized under a directive or regulation, the word Harmonized appear. When such an inscription does not appear, it means that the standard is related to / supporting the relevant directive or regulation.
