BS EN 13481-7:2012EN 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 ra
25、il 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 performan
26、ce. The method of measurement used should be suitable for the design of the particular fastening system. BS EN 13481-7:2012EN 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, fo
27、r 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 Tabl
28、e 1. Table 1 Fastening category criteria Category Maximum design axle load Minimum curve radius kN m A 130 40B 180 80 C 260 150D 260 400 E 350 150NOTE The maximum axle load for categories A and B does not apply to maintenance vehicles. The requirements apply to fastening systems which incorporate a
29、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.

42、following parts of switches and crossings shall comply with the requirements for fastening systems for plain line track in EN 13481-2, EN 13481-3, EN 13481-4 and EN 13481-5, as appropriate to the type of support: closure rails; rails supporting check rails; crossings; switch heels. When required by
43、the purchaser, torsional resistance shall be measured for closure rail systems only. 5.2 Longitudinal rail restraint When measured by the procedure in EN 13146-1, the longitudinal rail restraint shall be not less than 7 kN when anti-creep pads are used under stock rails. When no pads are used, the l
44、ongitudinal rail restraint shall be not less than 5 kN. On structures such as long bridges, the longitudinal force transmitted between the track and the structure may be calculated by the method in EN 1991-2. The value of Fmaxmeasured in accordance BS EN 13481-7:2012EN 13481-7:2012 (E) 9 with EN 131
45、46-1 may be used in the calculation. In such cases, and subject to agreement between the purchaser and manufacturer, the minimum requirement for longitudinal restraint may be reduced. 5.3 Torsional resistance When required by the purchaser, the torsional resistance of closure rails shall be measured
46、 by the procedure in EN 13146-2 and the result reported. 5.4 Assembly and pad stiffness As required by EN 13146-4, the assembly static stiffness and assembly low frequency dynamic stiffness shall be measured in accordance with EN 13146-9+A1. Measurement of the rail pad static stiffness is required a
47、t the purchasers discretion in accordance with EN 13146-8. If the purchaser requires any of the following it shall be measured in accordance with EN 13146-9+A1: pad low frequency dynamic stiffness; assembly high frequency dynamic stiffness. Test loads are given in EN 13481-2, EN 13481-3, EN 13481-4
48、or EN 13481-5, as appropriate. NOTE Guidance on the measurement of pad high frequency dynamic stiffness is given in EN 13146-9:2009+A1:2011, Annex A.
