铁路基础设施.轨道紧固系统.第7部分：夹紧力和上抬刚度的试验方法

[中文适用范围]： 本文件 specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. 当需要时，该程序还可用于确定紧固系统提升刚度。 它适用于所有类型轨枕、承载器或无砟轨道元件上的带和不带底板的系统。 本试验不测定固定在轨枕或其他紧固系统支撑中的紧固组件的安全性。 此试验程序适用于完整的扣件组件。 它不适用于嵌入式轨道或其他不对轨道足部施加作用的其他紧固系统。 [外文原描述]： This document specifies the laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of the rail by measuring the force to separate the rail foot from its immediate support. When required, the procedure is also used to determine the uplift stiffness of the fastening system. It is applicable to systems with and without baseplates on all types of sleepers, bearers or elements of ballastless track. The test does not determine the security of the fastening components fixed into the sleeper or other fastening system support. This test procedure applies to a complete fastening assembly. It is not applicable to fastening systems for embedded rail or other fastening systems which do not act on the foot of the rail.
