43、l 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 longitudinal displacement occurs. Longitudinal rail restraint or longitudinal stiffness
44、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 have loose rust on the surface nor be polished on the foot by repeated testing. For
45、 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 applying a tensile force of at least 40 kN to the longitudinal axis of the rail as s
46、hown 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 to the rail support with an accuracy of 0,02 mm. Non-contact instruments may be use
47、d 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 7500-1:2004, class 1 over the required range of force. 5.5 Verification of calibration The
48、 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 specimens 6.1 Rail support A sleeper, half sleeper, bearer or element of slab track, incorpo
