GB/T 18375.5-2004 in English

《GB/T 18375.5-2004假肢 下肢假肢的结构检验 第5部分:辅助结构检验》由TC148（全国残疾人康复和专用设备标准化技术委员会）归口，主管部门为民政部。
GB/T18375描述了下肢假肢的静态和动态试验过程，在这个过程中，除了一种特殊情况，都是用一个试验力产生复合的试验载荷。在试验样品上的复合载荷取决于载荷各个分力的峰值，这些峰值通常发生在行走过程中支撑相时的不同的瞬间。GB/T18375描述的检验方法适用于小腿(BK)假肢、膝离断假肢和大腿(AK)假肢。GB/T18375的本部分规定了GB/T18375.3和GB/T18375.4规定之外的结构试验和试验要求。试验及其所需测试的部件如下：扭力试验所有部件踝足装置试验所有踝足装置做为单个组件，包括踝部和踝连接件膝限位试验所有膝组件和在一完整假肢中和限位有关的零件膝锁试验在伸展位置锁定膝组件的所有机械装置

Scope

GB/T 18375 describes the static and dynamic test procedures for lower limb prostheses. In this process, except for one special case, a test force is used to generate a compound test load. The compound load on the test specimen depends on the peak values of the individual components of the load, which usually occur at different instants during the stance phase during walking. The test method described in GB/T 18375 is applicable to lower leg (BK) prostheses, knee amputated prostheses and thigh (AK) prostheses. This part of GB/T 18375 specifies structural tests and test requirements other than those specified in GB/T 18375.3 and GB/T 18375.4. The test and the components that need to be tested are as follows: Torsion test of all components Ankle-foot device test of all ankle-foot devices as individual components, including ankle and ankle joints Knee restraint test of all knee components and restraints in a complete prosthesis Knee lock test for relevant parts All mechanisms for locking the knee assembly in the extended position
