Impact hammer, with a cylindrical pendulum head having a mass of 6,5 kg, supported from a pivot by a steel tube of 38 mm in diameter and with a wall thickness of 2 mm.
This load pad is designed specifically for BIFMA X5.1, which is a rigid rectangle object 102×50 mm in dimension ,with a 12 mm front edge radius. Mainly used to test the office chair pedal static load and durability.
The purpose of this test is to determine: (1) retention of load bearing (65 % IFD), (2) a loss in thickness, and (3) structural breakdown as addressed by visual inspection. This procedure describes tests that evaluate the specimen by repeatedly deflecting the carpet cushion by a 152 mm diameter and 152 mm wide rubber covered roller exerting a force of 266±5N on the test specimens.
Arm Rest and Seat Back Testing Machine is equipped with five drive units, and can be individually controlled to repeatedly load the test points of the chair.
BIFMA127&60mm loading pad is designed specifically for BIFMA X5.1, which is a rigid rectangle object 127×60 mm in dimension ,with a 12 mm front edge radius. Mainly used to test the office chair arm static load and durability.
