30、 force representing 40 % of the self weight of the equipment with a minimum of 400 N. The force shall be applied at the middle of the bar and perpendicular to its length. 4.5 Vertical stiffness and residual deflection When each bar is tested in accordance with 5.4 using a force of 1 350 N 50 N, the

31、deflection of each bar shall be a minimum of 40 mm and a maximum of 100 mm. The residual deflection shall be no greater than 1 mm.
