Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 213, Cable
management.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50085-2-1
on 2006-10-01.
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) 2007-10-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-10-01

This standard is a system standard for cable management products used for electro-technical
purposes. It relates to the Council Directives on the approximation of laws, regulations and
administrative provisions of the Member States relating to Low Voltage Directive (73/23/EEC)
through consideration of the essential requirements of this directive.
This standard is supported by separate standards to which references are made.
This Part 2 is to be used in conjunction with EN 50085-1:2005, Cable trunking and cable ducting
systems for electrical installations – Part 1: General requirements.
This Part 2 supplements or modifies the corresponding clauses of Part 1. Where a particular
clause or subclause of Part 1 is not mentioned in this Part 2, that clause or subclause of Part 1
applies as far as is reasonable. Where this Part 2 states “addition” or “replacement”, the relevant
text of Part 1 is to be adapted accordingly.
Subclauses and figures which are additional to those in Part 1 are numbered starting from 101.

EN 50085-2-1:2006 – 8 –
Compliance is checked by inspection and measurement when the area intended to accommodate
insulated conductors is at least 10 mm above the floor due to
• design, or
• manufacturer’s instructions restricting the installation position of the CTS/CDS, or
• manufacturer’s instructions allowing all installation positions of the CTS/CDS but restricting
the position of insulated conductors and live parts in CTS/CDS.
In all other cases compliance is checked by the following test carried out on an assembly or
assemblies.
An assembly is made of one or more trunking lengths or ducting lengths with the relevant system
component, if any, to fulfil the various functions of the system and prepared according to the
manufacturer’s instructions. More than one assembly may be necessary to fulfil the various
functions of the system. In each direction, the length L of trunking length or ducting length coming
out of the functional area associated with the function of the system is as long as the width W of
the trunking length or ducting length, or 250 mm, whichever is the greater. The tolerance of L is
± 25 mm.
NOTE 1  Functional area refers, for example, to a fitting, an apparatus mounting device, a junction as shown in Figure 106
The assembly is fixed according to manufacturer’s instructions to an appropriate support. The
ends of the assembly are closed according to manufacturer’s instructions.
A (5 ± 1) mm wide strip of absorbent paper is placed on the lowest internal surface of CTS/CDS
intended for the accommodation of insulated conductors. If this lowest internal surface is
horizontal, the strip is placed approximately on the centre line of the surface. The absorbent paper
has a water absorptive height longitudinal of 75 mm per 10 min according to EN 20535 and a
basis weight of 250 g per m² according to EN ISO 536. The length of the strip is such that it
covers the whole length of the assembly.
NOTE 2  When the tested function of the system includes a change of direction, the length of paper can be made of more than
one strip.
Provisions are made such that the absorbent paper makes contact with the lowest internal surface
of CTS/CDS intended for the accommodation of insulated conductors along the whole length of
the assembly. These provisions shall not influence absorption by the paper.
The assembly is carefully placed in a tray containing water to simulate a (10 , 0/-1) mm height of
water on the floor.
NOTE 3  For easy measurement of wet area coloured water can be used.
After (15 ± 1) s the assembly is removed from the tray and the exterior of the assembly is
immediately wiped.
After careful removal of the access covers, if any, the abso
