Railway infrastructure — Rail fastening systems — Part 5: Test method for electrical resistance
Edition 1
2021-05
2021-05
Abstract
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.
