Road traffic noise reducing devices. Non-acoustic performance - Mechanical performance and stability requirements Ingestion-build-59651 Note 1: BS EN 1434‑5What is this standard about? This European Standard specifies criteria to categorize road traffic noise reducing devices according to basic mechanical performance under standard conditions of exposure, irrespective of the materials used. A range of conditions and optional requirements is provided in order to take into account the wide diversity of practice in Europe. Individual aspects of performance are covered separately in the annexes. Safety
