Railway infrastructure. Rail fastening systems. Two directional test method for resistance to repeated loading. | Status: Current

1 Scope This document describes a test procedure for the determination of resistance to repeated loading by – amongst others – applying out-of-phase load cycles which generate forces in two directions, representative of those caused by traffic on railway track, taking into account the effect of two consecutive axles of passing railway vehicles. The document applies to surface mounted rail on sleepers, bearers and slab track. The test procedure applies to a complete fastening assembly.
