Evaluation of long-term repeatability sofa bed load capacity, the test method similar Cornell (Cornell) life test.
Product use: testing the mattress on the long-term repeatability of load capacity, and the compression deformation of the mattress.
How it works: the sofa Cornell fatigue life test methods, driven by the motor eccentric wheel, adjusting the height of the impact of the impact of the block. and then to 120 ~ 160 times / min speed impact test mattresses. Counter measures the impact of the number. reaches Automatically shut down after the specified number of times.
Sofa mattress flat on the ground, through the computer system controlling a force perpendicular to the screw drive round mattress mattress pad in the measurement position to the speed of 100 ± 20mm, vertical down separately applied 4N, 40N , 200N, 250N force. 1Hd were measured circular pad applied 4N (the surface) of the distance .2 b 4N forces applied, and then increased to 200N displacement caused by the 4N force exerted .3 c, and then increased to 250N Caused by the displacement.
Circular pad made in accordance with ASTM F 1566-99.
Computer display, print force value, displacement, time tables.
