Railway applications - Track - Noise barriers and related devices acting on airborne sound propagation - Non-acoustic performance - Part 3: General safety and environmental requirements

This European Standard specifies minimum requirements and other criteria for assessing the general safety and environmental performance 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 of material characteristics may be required for the information of designers. The treatment of each topic is covered separately in Annexes A to G.

Bahnanwendungen - Oberbau - Lärmschutzwände und verwandte Vorrichtungen zur Beeinflussung der Luftschallausbreitung - Nicht akustische Eigenschaften - Teil 3: Allgemeine sicherheits- und umweltbezogene Anforderungen

Diese Europäische Norm legt Mindestanforderungen und andere Kriterien zur Bewertung der allgemeinen Sicherheit und der Gebrauchstauglichkeit im Hinblick auf Umweltbedingungen von Lärmschutzwänden und verwandten Vorrichtungen zur Beeinflussung der Luftschallausbreitung unter eisenbahntypischen Bedingungen fest. Die Anforderungen bei erschwerten Bedingungen müssen vom Konstrukteur berücksichtigt werden. Es werden geeignete Prüfverfahren zur Verfügung gestellt, sofern diese notwendig sind. Für manche Aspekte kann eine Erklärung der Baustoffeigenschaften zur Information des Konstrukteurs erforderlich sein. Jedes Thema wird in den Anhängen A bis G einzeln behandelt.

Applications ferroviaires - Voie - Écrans antibruit et dispositifs connexes influant sur la propagation aérienne du son - Performances non acoustiques - Partie 3 : Exigences générales pour la sécurité et l'environnement

La présente Norme européenne spécifie les exigences minimales et les autres critères d’évaluation de la sécurité générale ainsi que des performances relatives à l’environnement des écrans antibruit et des dispositifs connexes influant sur la propagation aérienne du son dans des conditions classiques d’installation en bordure de rails. Les exigences liées à des cas plus difficiles sont à prendre en compte par le concepteur. Des méthodes d’essai appropriées sont données chaque fois que cela est nécessaire mais, pour certains aspects, une spécification des caractéristiques du matériau destinée à l’information des concepteurs est susceptible d'être exigée. Chaque sujet est traité séparément dans les Annexes A à H.

Železniške naprave - Zgornji ustroj proge - Protihrupne ovire in pripadajoče naprave, ki vplivajo na širjenje zvoka v zraku - Neakustične lastnosti - 3. del: Splošne varnostne in okoljske zahteve

Ta evropski standard določa minimalne zahteve in druga merila za oceno splošne varnosti in okoljskih lastnosti protihrupnih ovir ter pripadajočih naprav, ki vplivajo na širjenje zvoka v zraku, v običajnih razmerah ob tirih. Zahteve za zahtevnejše razmere mora obravnavati projektant. Ustrezne preskusne metode so na voljo, kjer to potrebno, vendar bodo projektanti za nekatere vidike morda potrebovali informacije o lastnostih materiala. Vsaka tema je ločeno obravnavana v dodatkih od A do G.

EN 16727-3:2017 (E) 5 Introduction 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 people 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 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 fire. 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 the consequences of such impact load to establish the requirements for protection of rail users and passers-by.
