Requirements for fishplates manufactured to the corresponding rail sections in BS 11.

This Part of BS 47 specifies the chemical composition and tensile property requirements for the steel used, and the dimensions and tolerances of rolled steel fishplates intended for use with railway rails of linear mass equal to or greater than 24.8 kg/m (50 lb/yd).

The provisions of this specification are not restricted to fishplates for use with rails that comply with BS 11 and may be applied to fishplates for any rail section of 24.8 kg/m (50 lb/yd) or greater linear mass.

NOTE 1 Whilst this standard does not specify requirements for forged or cast fishplates some of its provisions may be applied to such products where appropriate.

NOTE 2 Recommended batch inspection procedures are described in Appendix A. The section properties are given for information in Appendix B. Information to be supplied by the purchaser is given in Appendix C.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
