Load Testing
Load Testing of Floorboxes to BS EN 50085 Part 2-2
(Clauses 10.5.103 and 10.5.104).
The floorboxes have been tested to and comply with the loading
requirements of BS EN 50085 Part 2-2 (Cable trunking systems
and cable ducting systems for electrical installations Part 2-2:
Particular requirements for cable trunking systems and cable
ducting systems intended for mounting underfloor, flushfloor, or
onfloor).
There are two loading criteria for the floorboxes - one with a
point loading to replicate foot traffic for example, and the other,
with a large plate to replicate fork trucks and heavier larger loads
for example. For both loading criteria the maximum allowable
deflection under load is 6mm and the maximum permanent
deflection after the load has been removed is 3mm.
The Lid Deflection (loading) graph shows that the maximum point
loading classification achieved is 3kN and the maximum large
plate loading classification achieved is 5kN.
The Permanent Deflection graph shows the permanent deflection
from the test wheel loading at 2kN is 0.3mm and large plate
loading at 5kN is 0.4mm. This is well within the maximum
allowable deflection of 3.0mm.
Note:
This test data specifically refers to the 265 x 265mm sized floorbox
frame assembly. The other floorbox sizes also comply with the required test
criteria. Declarations of conformity are available on request for the entire
range.
Cat 6 Compatibility
With Cat 6 & Cat 6A data cabling the orientation and depth of
many data outlets has changed resulting in the need for greater
backbox depths and wiring space to accommodate these longer
data outlet. No longer is a 35mm wiring space sufficient to
ensure data terminations can be made to the manufacturer’s
recommendations to prevent transmission losses.
45mm wiring space for the Cablelink Plus floorbox system is
available. This easily accommodates the longer Cat 6 & Cat 6A
data outlets and leaves sufficient space for the data cable to run
underneath it.
