What is BS EN 13715 about?
BS EN 13715 defines the tread profiles of wheels with a diameter equal to or greater than 330 mm used on rolling stock submitted to the Directive 2016/797/EU. These profiles apply to new wheels, whether free-standing or assembled as wheelsets, as well as to wheels that require reprofiling during maintenance.
BS EN 13715 describes the rules, parameters, and construction methods of the wheel tread profile.
Also, defines the geometry of the flange and reverse slope, the thicknesses, and height of the flange are determined by the railway undertaking or its representative.
BS EN 13715 defines the coordinates and geometry of the following three reference tread profiles of the wheels and their reverse slope:
- 1/40th (reverse slope 15 %)
- S1002 (reverse slope 6,7 %, other value used 15 %) in conformity with UIC Leaflet 510-2
- EPS (reverse slope 10 %) equivalent to profile P8 of the United Kingdom with a flange 30 mm thick.
Who is BS EN 13715 for?
BS EN 13715 on railway wheels is useful for:
- Railway engineer
- Mechanical engineer
- Manufacturers of wheelset and bogies
Why should you use BS EN 13715?
Wheel tread wear is a form of wheel damage that can seriously affect the performance of freight vehicles. BS EN 13715 describes the measurement of geometrical parameters of the rail wheel flange (thickness, slope, height), rim/tire thickness, and taking the full profile of the wheel roll surface.
BS EN 13715 provides three reference tread profiles used in Europe usually agreed on between the railway undertaking and the infrastructure manager.
BS EN 13715 gives the construction methods of wheels and axis of rotation of the wheel as well as the verification of the wheel profile.
Overall, BS EN 13715 can help you in manufacturing the railway wheelset to ensure its strength, durability, and safety during maintenance.
