Clause Test item Verdict
at one front corner flush to each structural edge without impact so that it takes the entire load without
any support from the cycling device, at a rate of 10 to 30 cycles per minute.
Test for 4,000 cycles. Reposition the load to the other front corner, and perform the test for an
additional 4,000 cycles.

Arm Strength Test – Vertical – Static
This test applies to all chairs with arms.
A loading adapter that is 127 mm (5 in.) long and at least as wide as the width of the arm shall be
attached to the top of the arm rest structure such that the load will be applied at the apparent
weakest point that is forward of the chair backrest.
Functional load:
A force of 750 N (169 lbf) shall be applied for one (1) minute then remove the force.
There shall be no loss of serviceability. For a height adjustable arm, failure to hold its height
adjustment position to within 6 mm (0.25 in.) from its original set position as the result of the loading
is considered a loss of serviceability.
Proof load:
A force of 1125 N (253 lbf) shall be applied for one (1) minute then remove the force.
There shall be no sudden and major change in the structural integrity of the chair. For a height
adjustable arm, a sudden drop in height of greater than 25 mm (1 in.) does not meet this
requirement. Loss of serviceability is acceptable.

Arm Strength Test – Horizontal – Static
This test applies to all chairs with arms.
A loading device or strap, not greater than 25 mm (1 in.) in horizontal width, shall be attached to the
arm so that the load is initially applied horizontally to the armrest structure at the apparent weakest
point.
Functional load:
A force of 445 N (100 lbf) shall be applied for one (1) minute in the outward direction and remove the
force.
A Normal (Functional) load applied once shall cause no loss of serviceability.
Proof load:
A force of 667 N (150 lbf) shall be applied for one (1) minute in the outward direction and remove the
force.
An Abnormal (Proof) load applied once shall cause no sudden and major change in the structural
integrity of the unit. Loss of serviceability is acceptable.

Backrest Durability Test – Cyclic – Type l
This test shall be performed on Type I Tilting chairs.
A weight of 109 Kg (240 lb.) shall remain in the center of the seat and be secured if necessary.
Apply a force of 445 N (100 lbf) that is initially 90 degrees ± 10 degrees to the plane of the backrest
for 25,000 cycles. When testing multiple-seating units, the durability test shall be performed on each
backrest positions one by one on the same sample.
The loading device shall be set at a rate between 10 and 30 cycles per minute.
For Safety Level – Stage 1: there shall be no loss of serviceability.
For Safety Level – Stage 2 or Performance Level (Stage 3): the product shall not show sudden and
major change in structural integrity. The product can show minor damage or loss of serviceability

Backrest Durability Test – Cyclic – Type Il and lll
This test shall be performed on Type Il and lll chairs.
If adjustable features are available, all adjustments shall be set at normal use conditions.
A weight of 109 Kg (240 lb.) shall remain in the center of the seat and be secured if necessary.
The loading device shall be adjusted to apply a 334 N (75 lbf) total force to the backrest for 25,000
cycles. When testing multiple-seating units the durability test shall be performed on each backrest
positions one by one on the same sample.
