23、3 BST 2006, Uncontrolled Copy, (c) BSIEN 13481-8:2006 (E) 4 Introduction Axle loads of up to 310 kN are in use on some European railways but the scope of EN 13481 Parts 2 to 7 has a maximum of 260 kN axle loads. This European Standard includes requirements for fastening systems for use on concrete,
24、wood and steel sleepers in ballasted track carrying axle loads up to 350 kN and in track where the minimum radius of curvature on main lines is less than the minimum in EN 13481 Parts 2 to 4. Tracks with high axle loads and small radius curves require heavy duty fastening systems complying with the
25、requirements of this European Standard. Heavy duty fastening systems are also recommended for use in the following conditions. tracks carrying a high proportion of axle loads in the range 225 kN to 260 kN; main line tracks with fastening systems incorporating medium or hard pads with minimum curve r
26、adii in the range 80 m to 150 m; main line tracks with fastening systems incorporating soft pads, where a significant proportion of trains with axle loads in the range 200 kN to 260 kN travel with high cant excess. A class of high attenuation of dynamic loading is included for use when it is necessa
27、ry to protect concrete sleepers from vehicle induced impacts. 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. Licensed Copy: Wang Bin, na, Mon
28、Jul 31 08:51:23 BST 2006, Uncontrolled Copy, (c) BSIEN 13481-8:2006 (E) 5 1 Scope This European Standard is applicable to fastening systems for use on concrete, wood and steel sleepers in main line ballasted track having a radius of curvature greater than 80 m and subject to a maximum design axle lo
29、ad of 350 kN. The requirements apply to: direct and indirect fastening systems; fastening systems for the rail sections in EN 13674-1 and EN 13674-4. This European Standard is not applicable to fastening systems for other rail sections, rigid fastening systems or special fastening systems used at bo
30、lted joints. This European Standard is for type approval of a complete fastening assembly only. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

When necessitated
39、by the design of the supporting structure, and subject to agreement between the purchaser and manufacturer, the minimum requirement for longitudinal restraint may be reduced. 5.2 Torsional resistance The torsional resistance shall be measured by the procedure in EN 13146-2 and the result reported. 5
40、.3 Attenuation of impact loads For fastening systems for concrete sleepers described as having medium or high attenuation of dynamic loads this shall be measured by the procedure in EN 13146-3 using the type of sleeper (monoblock or two block) on which the fastening is to be used. The result shall c
41、omply with the following limits: medium attenuation 15 % 30 %; high attenuation 30 %. 5.4 Effect of repeated loading This shall be determined by the procedure in EN 13146-4. Test loads for the track type specified in Table 1 shall be in accordance with Table 2. The value of Pv/cos shall be obtained
42、from Table 2 for the assembly design under test. The values in Table 2 have been derived for the track class shown in Table 1.
