In Tilting Chairs – To evaluate the ability of the tilt mechanism to withstand the fatigue stress and wear caused by repeated tilting.
A load of 45kg. is placed on the seat and back pulled/pushed without over riding or impacting both ends of the mechanism at the vertical center-line for 75000 cycles at the rate of 10 to 30 cycles per minute.
No loss of serviceability to the tilt mechanism
To evaluate the ability of the pedestal to withstand stressed as those caused by excessive vertical forces.
A load of 1050 kg for PP base and 1200 kg for metal base; applied twise for a period of 1 minute.
No structural breakage or cracks in the pedestal should happen. There shall not be sudden or major change in the structural integrity of the base. This center column should not touch the test platform during the load applications.
TEST ON PEDESTAL BASE CHAIRS WITH CASTERS
To evaluate the ability of the chair base to withstand fatigue stressed and wear caused by moving the chair back and forth.
A load of 120 kg placed in a hopper and mounted on the pedestal base with caster free to rotate and swivel. The chair is pulled/pushed to and fro with a stroke length of approx 762mm for 2000 cycles over and obstacles and then 98000 cycles without the obstacle at the rate of 10+/- 2 cycles per minute.
No loss of the serviceability to the movement of the casters.
HOF has also adopted some of the most unique and exclusive test equipment for strength and stability of tables and trolleys. These tests conform to guidelines laid down by Bureau of Indian standards (his)
to verify the ability of table to withstand overturning, a horizontal impactor of 50 kg. Through the ball is applied. The table should not overturn.
These tests are also carried out at our in house latest test equipments to validate the design of tables in respect of strength and stability as per 1S:5967(Part-1) 1988.
The load and number of cycles selected as per above iss. These equipment has been inspected and approved by Govt. of India. D.G.S & D
These tests are carried out to validate the performance of tables in respect of strength and stability as per 1S:5967 (part-1) 1988 in our in house lab at regular interval.
The requirements of loading and frequency of load cycles are followed as per iss.
