700+ series round service outlet box - when higher loads are required

Load test certificates for the 700+ range of round floor boxes can be downloaded from this page.

All tests were carried out on the stainless steel versions. However, the structural integrity of the box is provided from the 4mm thick infill plate, and the galvanised support frame, and we would expect similar results to be obtained from the brass boxes.

700+ gives:

Steel infill plate increased from the standard 2.5mm thick to 4.0mm thick

Height adjustable inner frame manufactured from 1.5mm thick steel

For each test the stainless steel frame of the sample was placed beneath the test rig and was positioned on the floor. A calibrated displacement transducer was attached to a steel plate which was welded to a 25mm x 25mm steel loading indentor to measure the deflection at the geometric centre of the cover. The cover was located in place within the frame.

The load was applied by means of a hydraulic ram acting through the indentor. Load was monitored by means of a calibrated load cell located between the ram and the indentor. Load and deflection were recorded by means of a calibrated datalogger.

This 25x25mm point load of 1.5kN / 3kN / 4.5kN / 6kN was held for 5 minutes and the deflection recorded. The load was then removed and the deflection recorded 1 minute after removal of the load.

Loading was then continued loading the sample to failure.
