Section 5 Backrest Strength Test – Static- Type I Test Procedure:
A force of 667N (150lbf) or 1001 N (225 lbf) shall be applied to the backrest at the backstop position for 0ne minute. Angle 70 ± 10 degrees, If the backrest/tilt lock mechanism will not accept the load due to gradual silpping of the adjustment mechanism during the load application, set the backrest to its most rearward(stopped) position, then apply the specified load(s). Remove the load
Section 6 Backrest Strength Test – Static- Type II & III Test Procedure:
Same with section 5, only the force should be 667N (150lbf) or 1001 N (225 lbf), Angle 90 ± 10 degrees.
Section 12 Arm strength Test- Vertical- Static Test Procedure:
A force of 750 N (169 lbf) or 1125 N (253 lbf) shall be applied for one minute. Remove the force
Section 13 Arm strength Test- Horizontal- Static Test Procedure:
A force of 445 N (100 lbf) or 667 N (150 lbf) shall be applied for 15 second in the outward direction.
Remove the force.
Section 14 Backrest Durability Test – Cyclic – Type l Test Procedure:
For chairs with backrest widths less than or equal to 406 mm (16 in.) at the height of the loading point, apply the load to the backrest for 120,000 cycles.
For chairs with backrest widths greater than 406 mm (16 in.) at the height of the loading point, apply the load to the backrest for 80,000 cycles.
Section 15 Backrest Durability Test – Cyclic – Type Il and lll Test Procedure:
For chairs with backrest widths less than or equal to 406 mm (16 in.) at the height of the loading point, apply the load to the backrest for 120,000 cycles.
For chairs with backrest widths greater than 406 mm (16 in.) at the height of the loading point, apply the load to the backrest for 80,000 cycles.
