Railway infrastructure — Rail fastening systems — Part 4: Test methods for resistance to repeated loading

Infrastructure ferroviaire — Systèmes de fixation du rail — Partie 4: Méthode d'essai pour la détermination de résistance aux charges répétitives

Abstract / scope

This document specifies a laboratory test procedure for applying repeated load cycles which generate displacement cycles representative of the displacements caused by traffic on railway track. It is used for assessing the long-term performance of rail fastening systems.

This document is applicable to surface mounted rail on sleepers, bearers and slab track and embedded rail.

This test procedure applies to a complete fastening assembly.
