Load Testing
Load Testing of Floorboxes to EN50085 Part 2-2 (Clauses 10.5.103 and
10.5.104).
The floorboxes have been tested to and comply with the loading requirements
of EN50085 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 265x265mm 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 the introduction of Cat 6 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. As a result MK has introduced 45mm wiring space for the Cablelink
Plus Floorbox systems (as well as for the Prestige 3D wall trunking system).
This easily accommodates the longer Cat 6 data outlets and leaves sufficient
space for the data cable to run underneath it.
