DIN EN 16727-3:2017-05 EN 16727-3:2017 (E) 5Introduction While performing their primary function, noise barriers and related devices acting on airborne sound propagation installed along railways should not pose hazards to rail users or other peop

29、le in the vicinity or to the environment at large. Noise barriers and related devices should not assist the spread of fire from adjacent verges or nearby land. Fire resistance in accordance with particular standards can in addition be required to minimize risk to adjacent premises, or to rail users

30、in confined corridors. Noise barriers and related devices should not reflect light towards train drivers in such a way as to compromise rail safety. They should be made from materials which do not emit noxious fumes or leachates as the result of natural or industrial processes, or as the result of f

31、ire. Noise barriers should allow a means of escape by rail users and access by operatives in the event of an emergency. Noise barriers and related devices acting on airborne sound propagation are not, in general, expected to resist the impact of vehicles, but designers can utilize information about

32、the consequences of such impact load to establish the requirements for protection of rail users and passers-by. DIN EN 16727-3:2017-05 EN 16727-3:2017 (E) 61 Scope This European Standard specifies minimum requirements and other criteria for assessing the general safety and environmental performance

33、of noise barriers and related devices acting on airborne sound propagation under typical rail-side conditions. Requirements for more onerous conditions are a matter for consideration by the designer. Appropriate test methods are provided where these are necessary, but for some aspects a declaration

34、of material characteristics may be required for the information of designers. The treatment of each topic is covered separately in Annexes A to G. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicatio
