EN 13481-7:2012 (E) 5 Introduction Various tests are necessary to assess the performance for fastening systems of railway tracks. In this European Standard, a requirement for longitudinal rail restraint is included to control rail creep. The laboratory test for the effect of repeated loading is the means of assessing potential long term performance of the fastening in track. The test for clamping force is only suitable for laboratory use. The measurement of clamping force in track can be used to monitor long term performance. The method of measurement used should be suitable for the design of the particular fastening system. SIST EN 13481-7:2012



EN 13481-7:2012 (E) 6 1 Scope This European Standard specifies performance requirements for special fastening systems, in categories A – E as specified in EN 13481-1:2012, 3.1, for switches and crossings and check rails secured within the overall fastening system (not independently fixed to the bearers) on wood, concrete and steel bearers, in ballasted track and on slab track and which have maximum axle loads and minimum curve radii in divergent track in accordance with Table 1. Table 1 — Fastening category criteria Category Maximum design axle load Minimum curve radius
kN m A 130 40 B 180 80 C 260 150 D 260 400 E 350 150 NOTE The maximum axle load for categories A and B does not apply to maintenance vehicles.
The requirements apply to fastening systems which incorporate a resilient element and act on the foot and/or web of the rail and which are intended for use with stock rail sections in EN 13674-1 (excluding 49E4) and EN 13674-4+A1. This standard is not applicable to rigid fastening systems. This standard is for type approval of a complete fastening assembly only. Requirements for quality control are included in the standards applicable to individual components. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
