标准摘要
[中文适用范围]： 本文件规定了实验室试验程序，用于施加重复载荷循环，产生代表铁路轨道上交通引起的位移的位移循环。其用于评估铁路扣件系统的长期性能。本文件适用于铺设在轨枕、承轨层和板式轨道上的表面安装钢轨以及嵌入式钢轨。本试验程序适用于完整的扣件组件。 [外文原描述]： This document specifies a laboratory test procedure for applying repeated load cycles which generate displacement cycles representative of the displacements caused by traffic on railway track. It is used for assessing the long-term performance of rail fastening systems. This document is applicable to surface mounted rail on sleepers, bearers and slab track and embedded rail. This test procedure applies to a complete fastening assembly.
