1 Scope This document is applicable to fastening systems, in Categories A – E as specified in EN 13481‑1:2012, 3.1 for use on wood or polymeric composite sleepers in ballasted or ballastless track, including track on open deck bridges, with respective maximum axle loads and minimum curve radii as shown in Table 1. Table 1 — Fastening category criteria Category Maximum design axle load kN Minimum curve radius m A 130 40 B 180 80 C 260 150 D 260 400 E 350 150

NOTE The maximum axle load for Categories A and B does not apply to maintenance vehicles.

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 for rail sections included in EN 13674‑1:2011+A1:2017 (excluding 49E4) or EN 13674‑4:2019.

This document is not applicable to fastening systems for other rail sections, rigid fastening systems, special fastening systems used at bolted joints or glued joints or special low clamping force fastenings used to mitigate track-bridge interaction effects. This document is for type approval of complete fastening systems.
