What is BS EN 13481-2 - Fastening systems for concrete sleepers about ?
BS EN 13481-2 discusses fastening systems for concrete sleepers.
Note1: BS EN 13481-2 is applicable to fastening systems in Categories A–E as specified in EN 13481-1:2012, 3.1, for use on concrete sleepers in ballasted track with maximum axle loads, and minimum curve radii.
Note2: The requirements apply to:
- Fastening systems that act on the foot and/or web of the rail including direct fastening systems and indirect fastening systems
- Fastening systems with dynamic stiffness, kLFA, not less than 50 MN/m
- Fastening systems for rail sections included in EN 13674-1 (excluding 49E4) or EN 13674-4
Note3: BS EN 13481-2 is not applicable to fastening systems for other rail sections, rigid fastening systems or special fastening systems used at bolted joints or glued joints.
Note4: BS EN 13481-2 should only be used for type approval of complete fastening systems.
Who is BS EN 13481-2 - Fastening systems for concrete sleepers for ?
BS EN 13481-2 on fastening systems for concrete sleepers 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 13481-2 - Fastening systems for concrete sleepers ?
The fastening system is designed with controlled clip guidance from the parked to the in-service position. BS EN 13481-2 is used to assess the suitability of fastening systems for use in railway track. BS EN 13481-2 specifies classes for attenuation of dynamic loading are included for use when it is necessary to protect sleepers from vehicle-induced impacts.
BS EN 13481-2 provides requirements for fastening systems for concrete sleepers which helps to prevent construction failures and accidents when using fasteners.
What is changed since the last update ?
BS EN 13481-2:2012+A1:2017 supersedes BS EN 13481-2:2012 which is withdrawn.
BS EN 13481-2:2012+A1:2017 includes some technical changes with respect to BS EN 13481-2:2012. These include:
- New categories of fastening systems have been introduced
- The ranges of test loads have been extended to cover the new categories of fastening system
- Advice on the attenuation of noise and vibration has been added in a new annex (Annex B)
