Chair Seat Rotating Testing Machine is used to test the durability of the seat swivel of the chair.
It apply to all kind of office chair which with swivel platform, used to evaluate the office chair to withstand repeated pressure and wear ability in rotation. It provide two mode of testing:
1. Can set the clockwise and counter–clockwise angle ( 45°to 355°)
2. 360°rotation single direction

Chair Test Step
a) The chair shall be restrained on a platform. Either the seat or the platform shall be restrained from rotation.
b) If the seat adjustable, set it to the maximum seat position. Set all other adjustable features to the normal use condition.
c) A 122 kg (270 lb.) load shall be placed on the seat such that the centre of gravity of the load is 51 to 64 mm (2 to 2.5 in) forward of the centerline of the rotational axis as shown in Picture 1.
d) The cycling device shall be adjusted to rotate the lesser of the following: the available range of rotation or 360 degrees ± 10 degrees. If the available range of rotation is less than 360 degrees, the rotation of the test machine shall be adjusted such that the swivel mechanism touches but does not override the stops. The rotation may be either bidirectional or unidirectional.
e) For chairs that swivel 360 degrees, a cycle is one full rotation. For chairs that swivel less than 360 degrees, one cycle is rotating from one stop to the other stop.
f) The seat or platform shall rotate for 60,000 cycles at a rate between 5 and 15 rotations per minute.
g) If the seat height is adjustable set the height to its lowest position.
h) For all chairs, continue the test for an additional 60,000 cycles to a total of 120,000 cycles.
