scope:

This European Standard is applicable to fastening systems for use in attaching rails to the uppermost surface of concrete or asphalt slabs in non-ballasted track construction as follows: - main lines having radius of curvature greater than 150 m and subject to maximum design axle load of 260 kN; - light rail systems having a radius of curvature greater than 40 m and subject to a maximum design axle load of 130 kN. This includes fastening systems for floating slabs but does not include fastening systems for embedded rails. The requirements apply to the following: a) direct fastening systems; b) indirect fastening systems; c) fastening systems for the rail sections in prEN 13674-1 and prEN 13674-4; d) fastening systems which incorporate concrete elements which each have not more than one supporting element per rail. In the case of (d) the concrete element is considered to be part of the fastening system. If the system includes concrete elements which each have more than one supporting location per rail, those concrete elements are considered to be part of the slab and not part of the fastening system.
