铁路基础设施.轨道紧固系统.第3部分：抗拔性的验证负载试验方法

[中文适用范围]： 本文件规定了一个测试程序，以确认将钢轨紧固组件的锚固拉出轨枕或其他支撑元件所需的力大于规定值（即，这是“验证负载”测试）。 该测试适用于以下紧固系统的部件： a) 在轨枕或其他支撑元件的制造过程中浇注到混凝土中； c) 用螺钉固定或以其他方式固定在木材、聚合物复合材料或钢轨枕或其他支撑元件上。 b) 粘在混凝土的浇铸孔或钻孔中；或 此测试不适用于嵌入式导轨。 [外文原描述]： This document specifies a test procedure to confirm that the force necessary to pull the anchorage of a rail fastening assembly out of the sleeper or other supporting element is greater than a prescribed value (i.e. it is a "proof load" test). This test is for components of the fastening system which are: a) cast into concrete during the manufacture of sleepers or other supporting elements; b) glued into the cast or drilled holes in concrete; or c) screwed or otherwise attached to wood, polymeric composite or steel sleepers or other supporting elements. This test is not applicable to embedded rails.
