DIN EN 13481-4:2012-11 EN 13481-4:2012 (E) 4 Introduction A series of tests is used to assess the suitability of fastening systems for use in railway track. In this European Standard a requirement for longitudinal rail restraint is included to control
27、 rail creep and pull apart in the event of a broken rail. Measurement of torsional resistance is included for use in assessing the risk of track buckling. The laboratory test for the effect of repeated loading is specified to assess the potential long term performance of the fastening in track. The
28、test for clamping force is only suitable for laboratory use. DIN EN 13481-4:2012-11 EN 13481-4:2012 (E) 5 1 Scope This European Standard is applicable to fastening systems, in categories A C and E as specified in EN 13481-1:2012, 3.1, for use on rectilinear steel sleepers in ballasted track with max
29、imum axle loads and minimum curve radii in accordance with Table 1. Table 1 Fastening category criteria Category Maximum design axle load kN Minimum curve radius m A 130 40 B 180 80C 260 150E 350 150 NOTE The maximum axle load for categories A and B does not apply to maintenance vehicles. The requir
30、ements apply to: fastening systems which act on the foot and/or web of the rail including direct fastening systems and indirect fastening systems; fastening systems for the rail sections in EN 13674-1 (excluding 49E4) and EN 13674-4+A1. This standard is not applicable to fastening systems for other
31、rail sections, rigid fastening systems or special fastening systems used at bolted joints or glued joints. This standard is for type approval of a complete fastening assembly only. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and ar
