Testing of wall mounts
Testing of wall mounts has been performed. Testing procedure and results are presented below.
Testing specimen
Three brackets were handed by Multibrackets. They were of the same model but in different
lenghts. They had EAN-number 7350022730052, 7350022730014 and 7350022730045. For better
traceability internal numbers (12408, 12409 and 12410) was given to each specimen.
Testing equipment
All testing was performed in the departments servo hydralic testing machine MTS 160 kN / 1100
Nm with control unit Instron 8580. The machines internal position gauge and load gauge was used.

The machines load gauge is regularly calibrated by SP.
Testing procedure
A large beam was mounted on the machines piston. On top of the beam two L-shaped beams were
clamped with four heavy duty clamps. Horizontally, a steel plank connected the L-beams with
screws. The specimens were screwed onto the steel plank and the the screws that fitted in the wall
mounts slot was mounted on an aluminium plank. Onto the aluminium plank the load was applied
Testing procedure

screws. The specimens were screwed onto the steel plank and the the screws that fitted in the wall
mounts slot was mounted on an aluminium plank. Onto the aluminium plank the load was applied
via a steel ball (see Figure 1-5). The specimens were loaded in manual controll to approximately 1
kN and then unloaded to zero load. That procedure was done thereafter to both 4 kN and 5 kN.
Results
The load/position charts shows that all three wall mounts manage the 5 kN load (Figure 7-9). The
remaining deformation is less than 1 mm, and that is the remaining deformation of the hole setup,
not just in the tested wall mounts. The wall mounts shows no visible deformation after testing (see
