Road traffic noise reducing devices - Specifications

This European Standard specifies requirements for the following road traffic noise reducing devices (as defined in 3.1):
-   noise barriers (as defined in 3.2);
-   claddings (as defined in 3.5);
-   road covers (as defined in 3.6); and
-   added devices (as defined in 3.7).
These devices may 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 may be made of different materials for which specific standards are to 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 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 marking.
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 does not cover road surfaces or the airborne sound insulation of houses.

-   besteht die hauptsächliche Funktion eines baulichen tragenden Elements 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 können tragende Elemente getrennt von akustischen Elementen geprüft werden.
Sie können aus verschiedenen Werkstoffen gefertigt sein, für die spezifische bestimmte Normen in Übereinstimmung mit den hierin nachstehend beschriebenen Vorschriften Angaben anzuwenden sind. Einige der Werkstoffe können gefährliche Stoffe enthalten, aus diesem Grund müssen sämtliche Werkstoffe angegeben werden.
Dieses Dokument legt die wesentlichen Merkmale von Lärmschutzvorrichtungen an Straßen festund, die entsprechenden Evaluierungsverfahren fest, , und es spezifiziert die Festlegungen zur Evaluierung von Konformität und Kennzeichnung. Dieses Dokument behandelt akustische und nichtakustische Eigenschaften und das Langzeitverhalten, nicht jedoch Aspekte wie etwa Beständigkeit gegen Vandalismus oder Anforderungen an das äußere Erscheinungsbild.

– če je glavna naloga zvočnega elementa v napravi podpirati ali združevati akustične elemente, če je zvočni element del naprave za zmanjšanje hrupa, ki se uporablja ob cestah. Odvisno od zasnove naprave za zmanjšuje hrupa se lahko konstrukcijske elemente po potrebi preskuša ločeno od akustičnih elementov.

In the absence of European harmonized test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction website on EUROPA accessed through http://ec.europa.eu/enterprise/construction/cpd-ds/. 4.3 Manuals The following documentation shall be supplied by the manufacturer to the user or those parties responsible for installation and maintenance of the road traffic noise reducing device prior to the commencement of installation. a) installation instructions shall describe how the product (acoustic element, full noise barrier, etc.) shall be installed in order to be able to achieve the performance measured in the initial type testing; b) a maintenance manual shall specify measures which are necessary, or to be avoided, in order to maintain the durability of the acoustic performance, transparency, structural strength etc. 5 Testing and assessment methods Products covered by the standard, when required, shall be tested in accordance with the supporting standards indicated in Table 1, Table 2, Table 3, Table 4 and Table 5. Results of tests and/or calculations of the characteristics shall be declared in accordance with the appropriate supporting standard.

14 6 Assessment and verification of constancy of performance – AVCP 6.1 General The compliance of road traffic noise reducing devices with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by: — determination of the product type; — factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s). 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g. use of previously existing data, CWFT and conventionally accepted performance). Assessment previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. NOTE 1 Same AVCP system means testing by an independent third party. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for that same characteristics for all products within that same family NOTE 2 Products may be grouped in different families for different characteristics. Reference to the assessment method standards should be made to allow the selection of a suitable representative sample. In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance: — at the beginning of the production
