本文件规定了实验室试验程序，用于在潮湿条件下，测定安装在钢或混凝土轨枕、无砟轨道支架或元件上的扣件系统提供的运行轨道之间的电阻。 也适用于预埋钢轨。 本测试程序适用于完整的紧固件总成。它与信号电流有关，而与牵引电流无关。 包括参考程序和替代程序。

This document specifies a laboratory test procedure for determining the electrical resistance, in wet conditions, between the running rails provided by a fastening system fitted to a steel or concrete sleeper, bearer or element of ballastless track. It is also applicable to embedded rail. This test procedure applies to a complete fastening assembly. It is relevant to signalling currents, not to traction currents. A reference procedure and an alternative procedure are included.
