This European Standard is applicable to fastening systems, in categories A - D as specified in EN 13481 1:2012, 3.1, for attaching rails to the uppermost surface of concrete or asphalt slabs and for embedded rails in non-ballasted tracks, with maximum axle loads and minimum curve radii in accordance with Table 1. Table 1 - Fastening category criteria Category Maximum design axle load Minimum curve radius kN m A 130 40 B 180 80 C 260 150 D 260 400 NOTE The maximum axle load for categories A and B does not apply to maintenance vehicles. The requirements apply to: a) fastening systems which act on the foot and/or web of the rail including direct fastening systems and systems which incorporate a baseplate; b) fastening systems which incorporate concrete elements and which each have not more than one supporting element per rail, including booted concrete blocks and sleepers complete with boots; c) adhesive and mechanical fastening systems for embedded rail but excluding rail cast into road pavements. In the case of (b), 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. This standard is only applicable to fastening systems for rail sections in EN 13674-1 (except 49E4) and EN 13674-4+A1; it is not applicable to special fastening systems for use at bolted joints or glued joints. This standard is for type approval of a complete fastening assembly only.
