| Resumen: | This document specifies a laboratory test method for the application of repeated load cycles that generate displacements representative of those caused by traffic on railway tracks. It is used to assess the long-term performance of rail fastening systems. This document applies to rails fastened to the surface on sleepers, girders, and slab tracks, as well as to embedded rails. This test method applies to a complete fastening unit. This document amends EN ISO 22074:2024. |
