What is BS EN 13674‑4- Vignole railway rails about?
BS EN 13674 is a European standard that discusses railway applications including track and rail infrastructure.
BS EN 13674‑4 is the fourth part of a multi-series that specifies flat bottom Vignole railway rails from 27 kg/m to, but excluding 46 kg/m. Eight pearlitic steel grades are specified covering a rail hardness range of 200 HBW to 440 HBW and including non-heat-treated non-alloy steels, non-heat-treated alloy steels, heat-treated non-alloy steels and heat-treated alloy steels.
Note: There are 15 rail profiles specified in this document, but these may not be available in all steel grades.
Who is BS EN 13674‑4-Vignole railway rails for?
BS EN 13674‑4 on vignole railway rails is applicable to:
- Manufacturers and suppliers of railways equipment
- Rail manufacturers
- Railway authorities
- Train operating companies (TOCs)
Why should you use BS EN 13674‑4- Vignole railway rails?
Whenever possible BS EN 13674-4 is performance based, recognizes the European Quality System standard EN ISO 9001 and requires manufacturers to offer the latest proven technology to consistently satisfy the demanding quality of the required product. Rail grading is based on hardness rather than tensile strength.
The acceptance tests have been designed to control those characteristics of the rail steel and rail that are of relevance to the production of high-quality rails and the demands of the railway.
The steel grades covered by BS EN 13674-4 reflect trends in railway usage and heat-treated rails are included. One aspect of BS EN 13674-4, which is a complete break from tradition, is the inclusion of quality assurance and inspection clause as part of product integrity.
BS EN 13674‑4 provides users with dimensions, tolerance measurement as well as product quality requirements to achieve the product integrity necessary to ensure track safety.
By complying with the standardised design requirements under BS EN 13674-4, you can ensure safety and reliability in the operational efficiency of overall railway infrastructure, while improving service-life of track systems.
