What is BS EN 13146-2 - torsional resistance for fastening systems about?
The main function of rail fastening systems is to fix rails to railway sleepers or railroad ties. BS EN 13146-2 is a European Standard that discusses railway applications.
BS EN 13146-2 is the second part of the railway applications multi-series that specifies test methods for track fastening systems.
BS EN 13146-2 provides you with a laboratory test procedure to determine the moment necessary to rotate a rail, secured to a sleeper by a rail fastening assembly, through 1° in a plane parallel to the base of the rail. The value obtained can be used in track stability calculations.
This test procedure applies to a complete fastening assembly.
Note: The test is not applicable to embedded rails.
Who is BS EN 13146-2 - torsional resistance for fastening systems for?
BS EN 13146-2 on torsional resistance for fastening systems is useful for:
- Manufacturers and suppliers of rail fastening systems
- Railway management authorities 
- Train operator companies (TOCs)
- Infrastructure managers 
- Maintenance engineers and crew
- Inspection and testing department in railways
- Quality control personnel
- Safety and compliance bodies
Why should you use BS EN 13146-2 - torsional resistance for fastening systems?
For rail tracks to function effectively, the assembly and maintenance is as important as component quality and durability. BS EN 13146‑2 is a standard that helps you to determine torsional resistance right from calibration of instruments to preparing the test report.
BS EN 13146‑2 provides you with details on loading and measurement with fastenings in line as well as when fastenings offset. The moment of load displacement graph has been provided for your reference in BS EN 13146‑2.
BS EN 13146‑2-compliant tests for fastening systems ensures operational safety of the railway and vehicle with enhanced track stability. Apart from reduced risk of derailment, high-performance fastening systems can absorb rail shock thus improving comfort level for passengers. BS EN 13146-2 guidelines are a step towards keeping commuters and property safe by mitigating risks associated with track maintenance.
