What is BS 47-1 - Rolled steel fishplates specifications about?
BS 47 is a European standard that discusses fishplates for railway rails. BS 47-1 is the first part of multi-part series that 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) to manufacture high quality and durable rolled steel fishplates.
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: BS 47-1 does not specify requirements for forged or cast fishplates some of its provisions may be applied to such products where appropriate.
Who is BS 47-1 - Rolled steel fishplates specifications for?
BS 47-1 on rolled steel fishplates specifications is useful for:
- Rolled steel fishplates manufacturers
- Maintenance staff for railway traction system
- Test centres
- Regulatory authorities
Why should you use BS 47-1 - Rolled steel fishplates specifications?
A fishplate, splice bar or joint bar is a metal bar that is bolted to the end of two rails to join them together in a track. The name is derived from fish, a wooden bar with a curved profile used to strengthen a ship's mast.
BS 47-1 guides regarding the manufacturing of steel and fishplates.
BS 47-1 also guides you regarding the chemical composition, dimensions and properties, marking, tensile properties, templates and working gauges, freedom from defects, finishing, tolerances, chemical analysis, tensile tests, manufacturer’s test, certificate, and inspection of rolled steel fishplates to manufacture and maintain rolled steel fishplates quality and durability.
With obedience and compliance to BS 47-1, you can enhance the efficacy of rolled steel fishplates that are used in railway traction. In addition, can prolong the life of rolled steel fishplates.
What’s changed since the last update?
BS 47-1:1991 supersedes BS 47:1959, which is withdrawn. BS 47-1:1991 includes some changes with respect to BS 47:1959. These include:
- Requirements for fishplates, manufactured from rolled steel to the corresponding rail sections in BS 11 have been added.
- For the first time, fishplates of a fully metric design for the No. 113 A rail section have been added.
