Overview

EN 15153-4:2020 - published by CEN - specifies the functional and technical requirements for exterior audible warning devices on urban rail vehicles (metro, tram, light rail and local rail systems, per CEN‑CENELEC Guide 26). The standard covers device types, acoustic performance, mounting/placement principles, testing procedures and conformity assessment. It complements other parts of the EN 15153 series (visible warning devices and heavy‑rail horns).

Key topics and technical requirements

  • Device classes: long‑range, medium‑range and short‑range audible warnings, with permitted device types including warning horns, warning bells, soft bells (gongs) and whistles.
  • Range guidance: typical use ranges are noted (long ≈ up to 500 m, medium ≈ up to 50 m, short ≈ up to 10 m).
  • Acoustic performance (examples from the text):
    • Medium‑range warning horns: fundamental frequency 370 Hz ± 20 Hz or 660 Hz ± 30 Hz; A‑weighted level LpAF,max = 96 dB ± 5 dB.
    • Whistles (medium/short): peak frequency 1 300 Hz ± 300 Hz; LpAF,max = 96 dB ± 5 dB.
    • Warning bells (single impulse): duration 0.5–1.0 s, rise time ≤ 0.1 s, relevant frequency 1 000–4 000 Hz; LpAF,max = 96 dB ± 5 dB.
    • Recurring bell rates: 1.5–4.0 cycles/s (single‑stroke) or 20–40 cycles/s (motor‑driven).
  • Safety note: long‑range devices can cause hearing damage to persons close to the vehicle when sounded.
  • Testing & conformity: Clause 6 sets test conditions and required test reports for acoustic verification and conformity assessment. Simultaneous operation of devices is permitted; however, superimposed sounds are not subject to separate acoustic performance requirements.
