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.
