What is BS EN 13146‑9 about?  

BS EN 13146‑9 is the ninth part in the multi-series of documents that is applicable to test methods for fastening systems.

BS EN 13146‑9 specifies laboratory test procedures to determine the static and dynamic stiffness of rail pads, baseplate pads and complete rail fastening assemblies.

Who is BS EN 13146‑9 for? 

BS EN 13146‑9 on the determination of stiffness is useful for: 

Designer and producers of rail fastening systems
Railway management authorities 
Infrastructure managers 
Site supervisors 
Inspection and testing department in railways  
Train operator companies (TOCs)

Why should you use BS EN 13146‑9?  

The main function of rail fastening systems is to fix rails to railway sleeper or railroad ties. Fastening systems generally consist of rail anchors, rail tie plates, chairs, fasteners, spikes, screws, bolts, etc.

In this regard, BS EN 13146-9 includes laboratory test techniques for determining the static and dynamic stiffness of rail pads, baseplate pads, and entire rail fastening assemblies. BS EN 13146‑9 brings together test methods for measuring the stiffness of pads and fastening assemblies under static and low-frequency dynamic loading. This can assist you in ensuring that they can measure the displacement of the rail in relation to the supporting sleeper or another piece.  

Overall, adopting BS EN 13146‑9-compliant tests for fastening systems ensures operational safety of the railway and vehicle with enhanced rail track stability. With high-performance fastening systems, the ability to absorb rail shock can improve comfort levels for passengers.
