---------------------- Page: 8 ----------------------
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
