Caster/Chair Base Durability Test

Purpose
TEST ON PEDESTAL BASE CHAIRS WITH CASTERS
To evaluate the ability of the chair base to withstand fatigue stressed and wear caused by moving the chair back and forth.

Procedure
A load of 120 kg placed in a hopper and mounted on the pedestal base with caster free to rotate and swivel. The chair is pulled/pushed to and fro with a stroke length of approx 762mm for 2000 cycles over and obstacles and then 98000 cycles without the obstacle at the rate of 10+/- 2 cycles per minute.
