BS EN 13146-7:2019规定了实验室试验程序，通过测量将轨脚与其直接支撑分离的力，确定扣件系统施加在轨脚上的夹紧力。必要时，该程序也可用于确定紧固系统的抗拔刚度。它适用于所有类型的轨枕、承木或板式轨道元件上有或没有底板的系统。本试验不确定固定在轨枕或其他紧固系统支架上的紧固部件的安全性。交叉引用:ISO 7500-1:2018EN ISO 7500-1:2018EN 13481-1:2012购买本文件时可用的所有当前修订版均包含在购买本文件中。

BS EN 13146-7:2019 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 slab track. The test does not determine the security of the fastening components fixed into the sleeper or other fastening system support.Cross References:ISO 7500-1:2018EN ISO 7500-1:2018EN 13481-1:2012All current amendments available at time of purchase are included with the purchase of this document.
