Caster/Chair Base Durability Test for Pedestal Base Chairs
This test applies to pedestal base chairs with casters.
Place a 122 kg (270 lb.) load on the seat of the chair.
The stroke of the cycling device shall be adjusted to ensure a minimum of 762 mm (30 in) of travel.
The cycling device shall be operated at a rate of 10 ± 2 cycles per minute.
The chair or chair base shall be cycled 4,000 cycles over the obstacles and then 25,000 cycles on a
smooth, hard surface without obstacles.
At the conclusion of cycling, a 22 N (5 lbf) pull force shall be applied to each caster in line with the
caster stem centerline.
There shall be no loss of serviceability.
No part of the caster shall separate from the chair as a result of the application of the 22 N (5 lbf)
force.
NA

Front load test
If adjustable features are available, all adjustments shall be set at normal use conditions.
Functional load:
A force of 334 N (75 lbf) shall be applied once to each front leg individually for one (1) minute then
remove the force.
Normal (Functional) load(s) applied once in each direction shall cause no loss of serviceability.
Proof load:
A force of 503 N (113 lbf) shall be applied once to each front leg individually for one (1) minute then
remove the force.
Abnormal (Proof) load(s) applied once each direction shall cause no sudden and major change in
the structural integrity of the chair. Loss of serviceability is acceptable.

Side load test
The load shall be applied to the apparent weakest point (front-to-back) of the leg.
Functional load:
A force of 334 N (75 lbf) shall be applied once to a front and rear leg individually for one (1) minute
then remove the force.
Normal (Functional) load(s) applied once in each direction shall cause no loss of serviceability.
Proof load:
A force of 503 N (113 lbf) shall be applied once to a front and rear leg individually for one (1) minute
