I. Seat and back static/durability & seat front edge static tester

a. Pneumatic cylinder with load cell capacity 1000N (horizontal) & 2000N (vertical)

b. 1 horizontal cylinder & 1 vertical cylinder

c. Mechanism - a specified vertical load is applied first to the seat and the load is maintained when the horizontal load is applied. The force shall be maintained for 10±2s or 2±1 s(adjuastable). This constitutes on cycle.

d. Adjustable load direction (90° to the chair backrest)

e. Adjustable height

f. Loading pad - attched to the cylinder and can pivot freely

- Seat loading pad - attached to the vertical cylinder (refer attachment)

- Back loading pad -attached to the horizontal cylinder (refer attachment)

g. Electrontic predetermined counter (EPC) - 6 digit counter to stroke the cylinder up to 200,000 cycles

h. Compression air: ±6kg/m²

i. PLC programming & security code available

j. Single phase AC 220V

k. Speed: adjustable (10-20 cycle/minute)

II. Armrest upward & downward static test

a. Consists of 2cylinder. Both cylinder can be set to :

- Vertical position with adjustable horizontal distance(up to 1m)- to apply vertical downward force(up to 900 N) on the arm rest and to lift the chair off the platform.

b. The height is adjustable up to 1m.

c. Loading pad attached to the cylinder: removable, 100mm diameter, 50 mm thickness, 12mm radius rounded edges & flat surface.

d. 3 operation mode:

- Mode 1: operate 1st cylinder only (for chair with one sided armrest)

- Mode 2: operate 2nd cylinder only(for chair with one sided armrest)

- Mode 3: operated both cylinder simultaneously

e. Cycle required: 10 times

f. Force shall be maintained for 10±2 s.

III. Armrest sideways static load test

a. Consist of horizontal cylinder having 2loading pads (100mm diameter) fixd on opposite direction(refer attachment).

b. The cylinder is fixed on vertical post and height adjustable (500-1000mm)

c. The cylinder and loading pad assembly can fit between 2 arm rests (min.distance 400mm) so that the sideway force (max.900N)can be applied to the arm rest simultaneously through the loading pad.

g. Cycle required: 10times

h. Force shall be maintained for 10±2 s.

IV. Legs forward/sideways static tester

a. Consists of 1 cylinder which can be set to the horizontal and vertical position .

b. Load cell : capacity 1000N

c. The height is adjustable up to 1m

d. Loading pad attached to the cylinder:100mm diameter,50mm thickness,12mm radius rounded edges & flat surface.

e. Force application: 10 times,maintained for 10±2s.

V. Back/arm impact tester

a. Impact hammer

- Hanging and pivoting pendulum hammer for free fall

- Height adjustable (300-1000mm)

- Construction -refer attachment
