Specifies requirements for resilient fastenings for use in railway track. It covers all parts of the fastening assembly including clips, insulators, pads etc. Test methods are given in Appendices.

This Standard specifies requirements for resilient fastening assemblies for use in conjunction with steel rails and sleepers or other support structures for railway track for insulated and non-insulated applications. NOTES: 1 Purchasing and usage guidelines are given in Appendix A including, information to be supplied by purchasers and suppliers, typical fastening evaluation data sheets, and a method for evaluation in track. Also included is a set of typical test loads for various track situations. 2 Guidance on means of demonstrating compliance with this Standard is given in Appendix B.
