从墙壁与墙壁表面成直角，直到其重心位于其初始自由悬挂位置上方所需的摆动高度。然后松开袋子，让它摆动到墙上。在每个测试点上从每个挥杆高度进行两次冲击。当试验结构为无框架结构时，应尽可能靠近墙体长度的中点进行此操作。在距离门最远的墙端附近重复该操作。如果墙是框架结构，请选择框架和接缝（如果适用）线上和之间的冲击点。表中列出了提供所需冲击能量水平的摆动高度 from the wall at right angles to the face of the wall until its centre of mass is at the required height of swing above its initial free-hanging position. Then release the bag and allow it to swing pendulum-wise and strike the wall. Make two impacts from each height of swing on each point tested. When the test structure is of unframed construction, carry out this operation as near as possible to a point midway in the length of the wall. Repeat the operation near the end of the wall farthest from the door. If the wall is of framed construction, choose points of impact that are both between and on the line of the framing and joints (if applicable). The height of swing that provides the required level of impact energy is set out in table
