This European Standard provides criteria to categorise 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 to allow for the wide diversity of practice within Europe. Individual
aspects of performance are covered separately in the annexes. Safety considerations in the event of damage to
noise reducing devices are covered in Part 2 of this European Standard.
