NBN ENV 13481-6:2002

This European Prestandard specifies requirements for the performance of fastening systems for attaching rails to sleepers or longitudinal bearers or in non-ballasted track to the uppermost surface of concrete or asphalt slabs. It applies to track with a minimum curve radius greater than 40 m and subject to a maximum design axle load of 260 kN. It does not apply to embedded rails.
The requirements apply to direct fastening systems and systems which incorporate a baseplate. They are not applicable to systems which incorporate concrete elements or other high mass elements nor to special fastening systems used at bolted rail joints.
This European Prestandard is for type approval only.
