26、. For an embedded rail with an adhesive fastening system the test procedure measures the longitudinal stiffness. DIN EN 13146-1:2015-01 EN 13146-1:2012+A1:2014(E)6 1 Scope This European Standard specifies a laboratory test procedure to determine: a) the maximum longitudinal force that can be applied

27、 to a rail, secured to a sleeper, bearer or element of slab track by a rail fastening assembly, without non-elastic displacement of the rail occurring, or b) the longitudinal stiffness at a specified longitudinal displacement of a specimen of embedded rail with an adhesive fastening system. 2 Normat

DIN EN 13146-1:2015-01 EN 13146-1:2012+A1:2014(E)7 4 Principle A longitudinal load is applied by

34、pulling a rail fixed to a sleeper, bearer or element of slab track by one or two rail fastening assemblies or by an embedded rail fastening system whilst the support is restrained. Movement of the rail relative to the support is recorded and the load removed when the rail slips or the specified long

35、itudinal displacement occurs. Longitudinal rail restraint or longitudinal stiffness are obtained from a plot of load versus displacement. 5 Apparatus 5.1 Rail !A short length of rail of the section for which the fastening system under test has been designed. The rail shall be unlaminated and neither

36、 have loose rust on the surface nor be polished on the foot by repeated testing. For surface mounted rail, the length of rail used for testing shall be approximately 0,5 m. For embedded rail, the rail is part of the test specimen and its length is specified in 6.1.“ 5.2 Actuator Actuator capable of

37、applying a tensile force of at least 40 kN to the longitudinal axis of the rail as shown in Figure 1. 5.3 Displacement measuring instruments Instruments conforming to EN ISO 9513:2002, Table 2, Class 2. The instruments shall be capable of measuring the longitudinal displacement of the rail, relative

38、 to the rail support with an accuracy of 0,02 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. 5.4 Force measuring instruments Instruments conforming to EN ISO 7500-1

39、:2004, class 1 over the required range of force. 5.5 Verification of calibration The calibration of actuators and measuring instruments shall be verified using equipment having certified traceability to European or International Standards using the International System of Units (SI). 6 Test specimen

40、s 6.1 Rail support A sleeper, half sleeper, bearer or element of slab track, incorporating embedded rail where appropriate, complete with cast-in fastening components or holes, and rail seats, as made without modification for this test. DIN EN 13146-1:2015-01 EN 13146-1:2012+A1:2014 (E) 8 For fasten

41、ing systems incorporating continuous support of surface mounted rail, the test shall be performed using a length of pad equal in length to the design spacing of the fastening along the rail. The piece of rail used for the test shall be at least as long as the piece of pad. For surface mounted fasten

42、ing systems which have low frequency dynamic stiffness 50 MN/m, when tested in accordance with EN 13146-9, it may be necessary to carry out the test over two rail seats to provide greater stability. !For mechanically fastened embedded rail, the length of rail shall be the typical spacing of fastenin

43、gs. For adhesively fastened embedded rail, the length of the rail shall be 0,5 m to 0,85 m.“ 6.2 Fastening The complete fastening assembly includes all components and baseplate, where appropriate. 7 Procedure 7.1 Test temperature The test shall be carried out in a room or enclosure maintained at (23

44、 5) C. All components used in the test shall be kept at this temperature for no less than 4 h prior to the commencement of the test. 7.2 Preparation for test If not already in place, fix the short length of rail to one or two rail seats as necessary using the fastening components as assembled in tra

45、ck. Place the rail support on a rigid base and restrict any movement parallel to the rail as shown in Figure 1.

46、upport as described in 6.1 5 rigid support and restraint to prevent rotation of the rail support NOTE For fastenings which hold the rail foot, the force application should be at the rail foot and for fastenings which hold the rail web the force should be applied at the rail centroid. Figure 1 Test a

47、rrangement 7.3 Loading 7.3.1 Longitudinal rail restraint Apply a tensile load at a constant rate of (10 5) kN/min to one end of the rail. From the start of this loading cycle, automatically measure the load and longitudinal displacement of the rail relative to the sleeper. When the rail slips in the

48、 fastening assembly or if the load is more than four times the performance requirement, rapidly reduce the load to zero and continue measuring the rail displacement for two minutes. Without removing or adjusting the fastening assembly in any way repeat the above cycle a further three times with three minute intervals in the unloaded condition between each cycle. Plot the applied load against rail displacement for each cycle as shown in Figure 2. If the rail displacement is jerky, plot a media
