29、ordance with 5.2 the test pattern shall pass between the uprights. 4.3 Entrapment The entrapment requirements of EN 913 relate to the uprights, bars and connections between them. 4.4 Stability When tested in accordance with 5.3, equipment shall not tip in any direction when subjected to a horizontal
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.

32、n accordance with 5.5 using a vertical force of 2 850 N 50 N the equipment shall show no signs of fracture, rupture or defects. 4.7 Rigidity of framework When tested in accordance with 5.3, the bar at the supporting cup point shall not deflect by more than 20 mm in the longitudinal or the transverse
33、 direction when subjected to a horizontal force of 570 N 20 N in each of these directions. Transverse forces shall be applied to the middle of the bar and perpendicular to its length.
