Railway infrastructure — Rail fastening systems — Part 5: Test method for electrical resistance

Infrastructure ferroviaire — Systèmes de fixation du rail — Partie 5: Méthode d'essai pour la détermination de résistance électrique

Abstract / scope

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.
