24、012 (E) 5 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 rail creep and pull apart in the event of a broken rail. Measurement of torsional r
25、esistance is included for use in assessing the risk of track buckling. Classes for attenuation of dynamic loading are included for use when it it is necessary to protect sleepers from vehicle induced impacts. The laboratory test for the effect of repeated loading is specified to assess the potential
26、 long term performance of the fastening in track. The test for clamping force is only suitable for laboratory use. BS EN 13481-2:2012EN 13481-2:2012 (E) 6 1 Scope This European Standard is applicable to fastening systems, in categories A E as specified in EN 13481-1:2012, 3.1, for use on concrete sl
27、eepers in ballasted track with maximum axle loads and minimum curve radii in accordance with Table 1.

28、t apply to maintenance vehicles. The requirements 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 49 E4) and EN 13674-4. This standard is not a
29、pplicable to fastening systems for other 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 norma

43、The longitudinal rail restraint shall be not less than 7 kN when measured by the procedure in EN 13146-1. For use in category D fastening systems ( 250 km/h), the longitudinal rail restraint shall be not less than 9 kN. On structures such as long bridges, the longitudinal force transmitted between t
44、he track and the structure may be calculated by the method in EN 1991-2. The value of Fmaxmeasured in accordance with EN 13146-1 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 r
45、educed. 5.2 Torsional resistance When required by the purchaser, the torsional resistance shall be measured by the procedure in EN 13146-2 and the result reported. 5.3 Attenuation of impact loads For fastening systems described as having medium or high attenuation of dynamic loads this shall be meas
46、ured by the procedure in EN 13146-3 using the type of sleeper (mono-block or two block) on which the fastening is to be used. The result shall comply with the following limits: medium attenuation 15 % to 30 %; high attenuation 30 %. 5.4 Pad and assembly stiffness As required by EN 13146-4, the assem
47、bly static stiffness and assembly low frequency dynamic stiffness shall be measured in accordance with EN 13146-9. Measurement of the rail pad static stiffness is required at the purchasers discretion in accordance with EN 13146-8. If the purchaser requires either of the following, it shall be measu
48、red in accordance with EN 13146-9: pad low frequency dynamic stiffness; assembly high frequency dynamic stiffness. Test loads are given in Table 2.
