Road traffic noise reducing devices - Specifications
This document specifies requirements for the following road traffic noise reducing devices (as defined in 3.1):
- noise barriers (as defined in 3.4),
- claddings (as defined in 3.5),
- covers (as defined in 3.6), and
- added devices (as defined in 3.7).
These devices can include both acoustic and structural elements, where:
- an acoustic element is an element whose primary function is to provide a noise reducing device with sound insulation, diffraction and/or sound absorption, it is a part of noise reducing device to be used along roads, and
- a structural element is an element whose primary function is to support or hold in place acoustic elements, it is a part of noise reducing device to be used along roads. Depending upon the design of the noise reducing device, structural elements may potentially be tested separately from acoustic elements.
They can be made of different materials for which specific standards will be applied in accordance with the specifications prescribed hereafter. Some of the materials may contain dangerous substances, the reason why all the materials are declared.
This document identifies the relevant characteristics of road traffic noise reducing devices, the corresponding methods of evaluation and specifies the provisions on evaluation of conformity and marking.
This document covers acoustic, non-acoustic and long-term performance, but not aspects such as resistance to vandalism or requirements of visual appearance.
This document does not cover road surfaces.
This document consists of supporting standards as described in Clauses 2 and 4. The supporting standards have the following content:
- EN 1793 1 establishes the intrinsic characteristic of sound absorption under diffuse sound field conditions and EN 1793 5 establishes the intrinsic characteristic of sound reflection under direct sound field conditions;
- EN 1793 2 establishes the intrinsic characteristic of airborne sound insulation under diffuse sound field conditions and EN 1793 6 establishes the intrinsic characteristic of airborne sound insulation under direct sound field conditions;
- EN 1793 4 determines the intrinsic characteristic of sound diffraction for added devices;
- EN 1794 1 assesses the maximum load NRDs can withstand and determines the self-weight of an acoustic element, maximum load on structural elements, maximum bending moment, maximum deflection and impact of stones;
- EN 1794 2 describes requirements concerning danger of falling debris, light reflection, release of dangerous substances, environmental protection and transparency;
- EN 1794 3 describes resistance to brush fire and reactions to fire;
- EN 14389 1 and EN 14389 2 gives durability requirements for acoustic and non-acoustic parameters during the working live of the product.
Lärmschutzvorrichtungen an Straßen - Vorschriften
Dieses Europäische Norm legt die Anforderungen an folgende Lärmschutzvorrichtungen (wie in 3.1 definiert) an Straßen fest:
- Lärmschutzwände (wie in 3.4 definiert);
- Bekleidungen (wie in 3.5 definiert);
- Überdeckungen (wie in 3.6 definiert); und
- Wandaufsätze (wie in 3.7 definiert).
Diese Vorrichtungen dürfen sowohl akustische Elemente als auch tragende Bauteile umfassen, dabei:
- besteht die hauptsächliche Funktion eines akustischen Elements darin, eine Lärmschutzvorrichtung mit Schalldämmung, Schallbeugung und/oder Schallabsorption zur Verfügung zu stellen, es ist ein Teil einer Lärmschutzvorrichtung, die an Straßen verwendet wird, und
- besteht die hauptsächliche Funktion eines tragenden Bauteils darin, akustische Elemente zu stützen oder zu verankern, es ist ein Teil einer Lärmschutzvorrichtung, die an Straßen verwendet wird. In Abhängigkeit von der Ausführung der Lärmschutzvorrichtung dürfen tragende Bauteile getrennt von akustischen Elementen geprüft werden.
Sie dürfen aus verschiedenen Werkstoffen gefertigt sein, für die bestimmte Normen in Übereinstimmung mit den nachstehend beschriebenen Angaben anzuwenden sind. Einige der Werkstoffe können gefährliche Stoffe enthalten, aus diesem Grund werden sämtliche Werkstoffe angegeben.
Diese Europäische Norm legt die wesentlichen Merkmale von Lärmschutzvorrichtungen an Straßen und die entsprechenden Evaluierungsverfahren fest, und gibt die Festlegungen zur Evaluierung von Konformität und Kennzeichnung an.
Diese Europäische Norm behandelt akustische und nichtakustische Eigenschaften und das Langzeit-verhalten, nicht jedoch Aspekte wie etwa Beständigkeit gegen Vandalismus oder Anforderungen an das äußere Erscheinungsbild.
Diese Europäische Norm enthält einen Anhang ZA zur Leistungserklärung aller Typen von Lärmschutz-vorrichtungen und ihrer Elemente. Die Leistungserklärung für ein Element muss über einen stufenweisen Prozess in die Leistungserklärung der endgültigen/installierten Lärmschutzvorrichtung einfließen.

La présente Norme européenne spécifie les exigences relatives aux dispositifs de réduction du bruit du trafic routier suivants (tels que définis en 3.1) :
- écrans antibruit (telles que définis en 3.4),
- parements (tels que définis en 3.5),
- couvertures (tels que définies en 3.6), et
- dispositifs additionnels (tels que définis en 3.7).
Ces dispositifs peuvent inclure à la fois des éléments acoustiques et structuraux, sachant que :

- un élément structural est un élément dont la fonction principale est de soutenir ou de maintenir en place des éléments acoustiques ; il fait partie d'un dispositif de réduction du bruit à utiliser le long des routes. Selon la conception du dispositif de réduction du bruit, les éléments structuraux peuvent faire l'objet d'essais séparément.
Ils peuvent être fabriqués dans des matériaux différents, auxquelles s'appliquent des normes particulières selon les spécifications énoncées ci-après. Certains de ces matériaux peuvent contenir des substances dangereuses. C'est la raison pour laquelle tous les matériaux sont déclarés.
La présente Norme européenne identifie les caractéristiques des dispositifs de réduction du bruit du trafic routier et les méthodes d'évaluation correspondantes, et spécifie les dispositions relatives à l'évaluation de la conformité et du marquage.
La présente Norme européenne couvre les performances acoustiques, non acoustiques et à long terme, mais pas certains points tels que la résistance au vandalisme ou les exigences concernant l'aspect visuel.
Cette norme européenne fournit une annexe ZA pour la déclaration de performance de tous types de dispositifs de réduction de bruit et pour leurs éléments. Lorsqu'elle est préparée pour un élément, la déclaration de performance doit être incluse dans un processus en cascade dans la déclaration de performance du dispositif de réduction de bruit final / installé.

This European Standard identifies the relevant characteristics of road traffic noise reducing devices, the
corresponding methods of evaluation and specifies the provisions on evaluation of conformity and

This European Standard covers acoustic, non-acoustic and long-term performance, but not aspects such
as resistance to vandalism or requirements of visual appearance.
This European Standard provides Annex ZA for the declaration of performance of all types of Noise
Reducing Devices and for their elements. When prepared for an element, the declaration of performance
has to be included through a cascading process in the declaration of performance of the final / installed
Noise Reducing Device.
This European Standard does not cover road surfaces or the airborne sound insulation of houses.
