Clause Test item Verdict
Alternative A:
Apply a vertical load of 600 N (135 lbf), through a 200 mm (7.87 in.) diameter disk, the center of
which is 60 mm (2.4 in.) from the front center edge of the load-bearing surface of the seat.
Apply a horizontal force of 20 N (4.5 lbf) at the same level of the plane of the top of the seat. The
force shall be coincident with the side-to-side centerline of the seat.
The chair shall not tip over as the result of the force application.
A chair shall not tip over under load on a level surface and on an uneven surface.
Alternative B:
Apply a vertical load of 600 N (135 lbf), by means of the front stability loading fixture at a point 60
mm (2.4 in.) from the front center edge of the load-bearing surface of the chair.
Apply a horizontal force of 20 N (4.5 lbf) at the same level of the plane of the top of the seat. The
force shall be coincident with the side-to-side centerline of the seat.
The chair shall not tip over as the result of the force application.
A chair shall not tip over under load on a level surface and on an uneven surface.
Alternative C:
This test procedure (Alternative C) shall only be used for multiple seating units.
A downward force shall be applied initially at 45°± 5° to the test platform by attaching a strap, not to
exceed 76 mm (3 in) in width, centered over the front portion of the seat.
The force determined results the unit tipping over shall not be less than 40% of the total unit weight.

Backrest Strength Test – Static – Type I and II
This test does not apply to chairs with backrest height less than 200 mm (7.9 in.).
If adjustable features are available, all adjustments shall be set at midpoint.
Functional load:
Attach a loading device (front push or back pull) to the horizontal center of the backrest as
determined above. Apply a force of 667 N (150 lbf) that is initially 70 degrees ± 10 degrees to the
plane of the backrest for 1 minute. (For multiple seating, the force shall be applied simultaneously to
the two most adverse backrests for 1 minute.)
Remove the load.
Application of Normal (Functional) Load shall not result in loss of serviceability to the chair.
Proof load:
A force of 1001 N (225 lbf) shall be applied to the backrest at the backstop position for 1 minute. (for
Multiple seating, the force shall be applied simultaneously to the two most adverse backrests for 1
Minute.)
Remove the load.
Application of the Abnormal (Proof) loads shall cause no sudden and major change in the structural
integrity of the product. Loss of function is acceptable.

Backrest Strength Test – Static – Type III
This backrest strength test shall be performed on Type lll chairs with backrests greater than 200 mm
(7.9 in.) in height.
If adjustable features are available, all adjustments shall be set at normal use conditions.
Functional load:
Attach a loading device (front push or back pull) to the horizontal center of the backrest as
determined above. Apply a force of 667 N (150 lbf) that is initially 90 degrees ± 10 degrees to the
plane of the backrest. (For multiple seating, the force shall be applied simultaneously to the two most
adverse backrests for 1 minute.)
For units with 3 seats, the loads shall be applied to the center and one of the side seats. For units
with 4 seats, the loads shall be applied to the two center seats.
Remove the load.
A Normal (Functional) load applied once shall cause no loss of serviceability to the chair.
