2.2.6 Longitudinal restraint test

When tested in accordance with Appendix F.. using a test load of half the minimum clamping force specit’ied by the purchaser

(0.5Ff), the rail shall not move more than 5 mm during the initial 3 mm period, and there shall be no more than 0.25 mm of further movement of the rail during the remainder of the test period.

The fastening shall be capable of meeting the requirements of the test in either direction. The specified maximum loading to be

used in the testing shall reflect the track standard required.

2.2.7 Fastening uplift test

When tested in accordance with Appendix F. the recorded assembly clamping force (Frn). shall exceed the minimum value specified by the purchaser for clamping force. and the fastening system shall support a maximum test load of (but not exceeding 45 kN) without failure.

NOTE: Due to the inherent variability of this test, it is suggested that 3 samples be tested.

2.2.8 Fastening repeated load test

Vhen tested using the following methods, with lateral and vertical rail seat loads L1 and i. no fatigue cracking of the resilient

clip and no loss of function of the other components shall occur:

(a) For prestressed concrete sleepers. Appendix G. using the sleeper to be used in track.

(b) For steel sleepers. the method given in AS 1085.17.

(c) For other bases (including timber). Appendix G. using a suitable base that as close as possible approximates the in service

use.
