26、 DIN EN 13146-4:2015-01EN 13146-4:2012+A1:2014(E)4 1 Scope This European Standard specifies a laboratory test procedure for applying repeated displacement cycles representative of the displacements caused by traffic on railway track. It is used for assessing the long term performance of direct faste

27、ning systems. The procedure is applicable to surface mounted rail on sleepers, bearers and slab track, and embedded rail. This test procedure applies to a complete fastening assembly. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and

The load, position and line of application to be used are determ

39、ined from the vertical stiffness of the fastening assembly, axle loads and curve conditions of the track for which the fastening assembly is being tested. Performance is determined by the change in clamping force, longitudinal rail restraint, vertical stiffness and rail position, and visual inspecti

40、on of the components during test. 5 Apparatus 5.1 Rail Short lengths of rail (approximately 0,5 m per rail seat or longer if required), of the section for which the fastening assembly under test is designed. The rail shall be unlaminated and have neither loose rust on the surface nor be polished on

41、the foot by repeated testing. The head of the rail may be modified to accommodate the load application head except when testing fastenings which support the web of the rail. In this case, the dimension X, as shown in Figure 1, refers to the design rail section for the fastening assembly. !For embedd

42、ed rail, the rail is part of the test specimen and its length is specified in 6.1.“ 5.2 Actuator Actuator capable of applying a force of up to 150 kN in a cyclic manner at a frequency of (4 1) Hz. NOTE For simultaneous loading of two and four rail seats the required capacity will be correspondingly

43、greater. 5.3 Load application head A head in contact with the rail which is capable of transmitting the applied force to a rail at the required position relative to the rail head. 5.4 Displacement measuring instruments Instruments conforming to EN ISO 9513:2002, Table 2, Class 2. The instruments sha

44、ll be capable of measuring displacement of the rail, relative to the support, within 0,01 mm. Non-contact instruments may be used providing a procedure for verifying their calibration is used and recorded. NOTE Non-contact instruments are outside the scope of EN ISO 9513. 5.5 Force measuring instrum

45、ents Instruments conforming to EN ISO 7500-1:2004 and EN ISO 7500-1:2004/AC:2009, Class 1 and over the required range of force. DIN EN 13146-4:2015-01EN 13146-4:2012+A1:2014(E)7 5.6 Verification of calibration The calibration of actuators shall be verified periodically in accordance with EN ISO 7500

47、made without modification for this test. It is recommended that two sleepers or half sleepers are used if the cast-in fastening components or holes are non-symmetrical about the longitudinal centre line of the sleeper. For surface mounted rail on slab track, the fastening system shall be mounted in

48、the centre of the top of a reinforced concrete block. The length of the block, normal to the rail, shall be 500 mm and the width 300 mm. If, for stability, it is necessary to test two rail seats, the width of the block shall be 2 the design fastening spacing in the track. The depth of the block shall be the depth of the slab or (200 10) mm, whichever is the smaller. For surface mounted fastening systems on slab track, with continu
