BS EN 50085-2-42009 EN 50085-2-42009 – 2 – Foreword This European Standard was prepared by the Technical Committee CENELEC TC 213, Cable management systems. The text of the draft was ted to the al vote and was approved by CENELEC as EN 50085-2-4 on 2009-05-01. The following dates were fixed – latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement dop 2010-05-01 – latest date by which the national standards conflicting with the EN have to be withdrawn dow 2012-05-01 This European Standard is a system standard for cable management products used for electro- technical purposes. It relates to Low Voltage Directive 2006/95/EC 1 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 50085-12005 “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 50085-12005. Where a particular clause or subclause of Part 1 is not mentioned in this Part 2-4, that clause or subclause of Part 1 applies as far as is reasonable. Where this Part 2-4 states “addition” or “replacement”, the relevant text of Part 1 is to be adapted accordingly. NOTE The following numbering system is used – subclauses, tables and figures that are additional to those in Part 1 are numbered starting from 101; – additional anns are lettered AA, BB, etc. __________ 1 Directive 2006/95/EC of the European Parliament and of the Council of 12 December 2006 on the harmonisation of the laws of Member States relating to electrical equipment designed for use within certain voltage limits, OJ L 374, 27.12.2006, p. 10–19.

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 surfaces 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.
