Road traffic noise reducing devices - Non-acoustic performance - Part 3: Reaction to fire - Burning behaviour of noise reducing devices and classification
This European Standard is to give authorities, designers and specifiers information with respect to reaction to fire, smoke density and toxic fumes of materials used in noise reducing devices.
The combination of brushwood fire test, smoke density test and test for toxic fumes give in general enough safety information. This European Standard allows also for more stringent requirements for those situations when a higher level of safety is needed.
For noise reducing devices, this European Standard gives a method how to handle substantial components of non-homogeneous products (as defined in EN 13501-1 and ISO 5659-2) and how to handle non-homogeneous products and in which cases the influence of non-substantial components on the total result of the classification may be neglected.
The following effects are of interest: ignitability, burning droplets, smoke growth rate, smoke density, toxic fumes.
Lärmschutzvorrichtungen an Straßen - Nichtakustische Eigenschaften - Teil 3: Brandverhalten - Brennverhalten von Lärmschutzvorrichtungen und Klassifizierung
Ziel dieser Norm ist es, Behörden, Entwickler und Planer zu Brandverhalten, Rauchdichte und Entwicklung toxischer Rauchgase der Werkstoffe, die in Lärmschutzvorrichtungen verwendet werden, zu informieren.
Die Kombination aus Brandprüfung mit Unterholz, Rauchdichteprüfung und Prüfung auf toxische Rauchgase liefert im Allgemeinen hinreichende Angaben zur Brandsicherheit. In dieser Norm werden für Situationen, in denen ein höherer Grad an Sicherheit erforderlich ist, auch strengere Anforderungen berücksichtigt.
Für Lärmschutzvorrichtungen wird in dieser Europäischen Norm ein Verfahren für die Handhabung substantieller Bestandteile von nichthomogenen Bauprodukten (wie in EN 13501-1 und ISO 5659-2 festgelegt), sowie zur Handhabung nichthomogener Bauprodukte angegeben und aufgezeigt, in welchen Fällen der Einfluss von nichtsubstantiellen Bauprodukten auf das Gesamtergebnis der Klassifizierung vernachlässigt werden darf.
Folgende Wirkungen sind von Bedeutung: Entzündbarkeit, brennendes Abtropfen, Rauchentwicklungsrate, Rauchdichte, toxische Rauchgase.
Dispositifs de réduction du bruit du trafic routier - Performances non acoustiques - Partie 3: Réaction au feu - Comportement au feu des dispositifs de réduction du bruit et classification
La présente norme a pour but de fournir aux autorités, concepteurs et prescripteurs les informations (réaction au feu, densité des fumées et dégagement de vapeurs toxiques) relatives aux matériaux utilisés dans les dispositifs de réduction du bruit.
La combinaison de l'essai de feu de broussailles, de l'essai de densité de fumée et de l'essai des vapeurs toxiques fournissent généralement suffisamment d'informations de sécurité. La présente norme permet également d'imposer des exigences plus sévères pour les situations dans lesquelles un niveau supérieur de sécurité est nécessaire.
Pour les dispositifs de réduction du bruit, la présente Norme européenne donne une méthode pour gérer les composants substantiels des produits non homogènes (tels que définis dans EN 13501-1 et ISO 5659-2), pour gérer les produits non homogènes et pour savoir dans quels cas l'influence des composants non substantiels sur le résultat total de la classification peut être négligé.
Les effets suivants sont à noter : allumabilité, gouttelettes enflammées, accélération de la production de fumée, densité de la fumée, vapeurs toxiques.
Protihrupne ovire za cestni promet - Neakustične lastnosti - 3. del: Odziv na ogenj - Obnašanje pri gorenju in razvrstitev protihrupnih ovir
Namen tega evropskega standarda je zagotoviti organom, načrtovalcem in izdajateljem specifikacij informacije z zvezi z odzivom na ogenj, gostoto dima in prisotnostjo strupenih plinov v materialih, ki se uporabljajo v protihrupnih ovirah.
S kombinacijo preskusa gorenja podrasti, preskusa gostote dima in preskusa prisotnosti strupenih plinov se v splošnem zagotovijo zadostne varnostne informacije. Ta evropski standard dovoljuje tudi strožje zahteve za primere, v katerih je potrebna višja stopnja varnosti.
Za protihrupne ovire ta evropski standard podaja metodo za obravnavo bistvenih sestavnih delov nehomogenih proizvodov (kot je opredeljeno v standardih EN 13501-1 in ISO 5659-2) in obravnavo nehomogenih proizvodov, ter v katerih primerih se lahko zanemari vpliv nebistvenih sestavnih delov na skupni rezultat razvrščanja.
Pomembni so naslednji učinki: vnetljivost, goreče kapljice, hitrost nastajanja dima, gostota dima, strupeni plini.

EN 1794-3:2016 (E) 4 Introduction It is necessary to understand how different materials react to fire and what happens if it burns because this situation could have adverse effects on environment and human life and cause in special situations great consequences in economic or social aspects. In general, the brushfire test gives enough information for most applications for noise reducing devices. In case where more stringent requirements are necessary, further testing for reaction to fire will be done according to EN 13501-1. This European Standard also contains indications for smoke hazard; density and toxic fumes, because this could create dangerous situations for the traffic and nearby living people. Test for smoke density and toxic fumes are necessary in all cases. The European Standard for classification, the EN 13501 series, is clear in its classification. This European Standard defines specific tests to classify products and for Noise Reducing Devices. This European Standard give more information about how to prepare specimen and supporting constructions if they are needed in a way that this product can be tested according to the specific standards mentioned in the EN 13501 series.

EN 1794-3:2016 (E) 5 1 Scope This European Standard is to give authorities, designers and specifiers information with respect to reaction to fire, smoke density and toxic fumes of materials used in noise reducing devices. The combination of brushwood fire test, smoke density test and test for toxic fumes give in general enough safety information. This European Standard gives also information if more stringent requirements are requested for situations with a higher level of safety. For noise reducing devices, this European Standard gives a method how to handle substantial components of non-homogeneous products (as defined in EN 13501-1 and ISO/DIS 5659-2:2016) and how to handle non-homogeneous products and in which cases the influence of non-substantial components on the total result of the classification may be neglected. The following effects will be taken into account: ignitability, burning droplets, smoke growth rate, smoke density, toxic fumes. The European Commission Decision 96/603/EC establish the list of products belonging to Classes A ‘No contribution to fire ’. The materials, and products made from them, that are listed in the Annex to this Decision, will, on account of their low level of combustibility and subject to the conditions also set out in the Annex, be classified in Classes A1 and Class A1FL as provided for in Tables 1 and 2 of the Annex to Decision 2000/147/EC. For the purpose of this classification, no reaction-to-fire testing of those materials and products made from them is required. The products considered having no contribution to fire are excluded from this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

More severe fires from spilt fuel can arise as the result of traffic accidents. SIST EN 1794-3:2016
EN 1794-3:2016 (E) 7 Where a noise reducing device is in close proximity to property it can also be necessary to consider the need to ensure that fire is not spread from the highway. Where flammable systems are used, it is recommended that firebreaks of fire-resistant materials or other design are incorporated into the noise reducing device in order to prevent the propagation of fire. This clause is not applicable to such fire resistant material. This clause describes a test for a representative panel of a vertical noise barrier under normal exposure to brushwood fires at the roadside. It does not provide information on the results of exposure to more severe conditions e.g. ignition by burning spilt fuel. The test should not be used to provide information on the fire safety of claddings used for tunnels or partial covers over the highway. 5.1.2 Classification The noise reducing device, after being tested by the method given in 5.1.3, shall be classified as follows: — class 1: if the panel has been damaged to a greater extent than as defined for classes 2 and 3; — class 2: if the damaged area above either source is less than 0,06 m2 and extends to no more than 200 mm above the base of the panel, and the panel has not been burnt through to the other side; — class 3: if there is no damage other than discoloration. 5.1.3 Fire test Acoustic elements of at least 2 m long by 1,5 m high shall be tested by exposure to localized sources of fire at its base next to the fro
