Clause Test item Verdict
Proof load:
A force of 1001 N (225 lbf) shall be applied to the backrest at the backstop position (For multiple
seating, the force shall be applied simultaneously to the two most adverse backrests) for 1 minute.
Remove the load.
An Abnormal (Proof) load applied once shall cause no sudden and major change in the structural
integrity of the chair. Loss of serviceability is acceptable.

Drop Test – Dynamic
This test applies to all chair types.
For chairs with a seat height adjustment feature, set the adjustment to its highest position.
On multiple-seating units, all seating positions not being tested shall be loaded with 109 kg (240 lb.)
with the exception of the position to be impacted.
For chairs with seat height adjustment features, set height to its lowest position and repeat.
Functional load:
A test bag weighing 102 kg (225 lb.) shall be raised 152 mm (6 in.) above the uncompressed seat
and released one time.
Then remove the bag.
There shall be no loss of serviceability.
Proof load:
Repeat setup as in the Normal (Functional) test and increase the weight of the test bag to an
Abnormal (Proof) load of 136 kg (300 lb.).
The test bag shall be raised 152 mm (6 in.) above the uncompressed seat and released one time.
Then remove the bag.
There shall be no sudden and major change in the structural integrity of the chair. Loss of
serviceability is acceptable.

Swivel Test – Cyclic
This test applies to all chair types with a swivel seat.
a) If the seat height is adjustable, set it to the maximum seat height position. Set all other
adjustable features to the normal use condition.
A 122 kg (270 lb.) load shall be placed on the seat such that the center of gravity of the load is 51 to
64 mm (2 to 2.5 in.) forward or rearward of the centerline of the rotational axis.
The seat or platform shall rotate for 30,000 cycles at a rate between 5 and 15 rotations per minute.
b) If the seat height is adjustable set the height to its lowest position.
For all chairs, continue the test for an additional 30,000 cycles to a total of 60,000 cycles.
There shall be no loss of serviceability.

both the impact and load-ease tests.
Safety Level – Stage 2 or Performance Level (Stage 3): The product must not show sudden and
major change in structural integrity after completion of both the impact and load-ease tests. The

Impact test
If adjustable features are available, all adjustments shall be set at normal use conditions.
A test bag weighing 57 kg (125 lb.) shall be attached to a cycling device, permitting a free fall from
30 mm (1.2 in.) above the uncompressed seat.
The cycling device shall be set at a rate between 10 and 30 cycles per minute.
For Multiple Seating, all seats not being cycled shall be loaded with 109 kg (240 lb.) of weight per
seat. And each seat on the same sample shall be subjected to the test.
