EN1335 Chair Loading Points (110 Kg in point A)

EN 1335 Castor and Chair Base Test Procedure:

Load the seat in point A with 110 Kg. The base shall be loosely fixed in such a way that there is no rotation of the base but that the natural movements of the castors during testing are not prevented. Alternatively attach the chair to a device that provides a linear movement of (1000±250) mm and a test surface. The angle of rotation shall be from 0⁰ to 180⁰ and back. One rotation and one rotation backward constitutes one cycle. The castors shall be left free to swivel, the device shall move with a rate of 6 cycles per minute.

Test Procedures

a) The chair or chair base shall be cycled 2,000 cycles over the obstacles as shown in Figure 16b and then

98,000 cycles on a smooth, hard surface (steel preferred) without obstacles.

b)  At the conclusion of cycling, a 22 N (5 lbf.) pull force shall be applied to each caster in line with the

    caster stem centerline.
