Road traffic noise reducing devices - Non-acoustic performance - Part 1: Mechanical performance and stability requirements
This European Standard specifies criteria to categorize road traffic noise reducing devices according to basic mechanical performance under standard conditions of exposure, irrespective of the materials used. A range of conditions and optional requirements is provided in order to take into account the wide diversity of practice in Europe. Individual aspects of performance are covered separately in the annexes. Safety considerations in the event of damage to noise reducing devices are covered in EN 1794-2.
This European Standard covers the current behaviour of the product. In order to assess its long term performances, EN 14389-2 should be used.
NOTE The test procedure described in Annex A doesn't consider the fatigue effect.
Lärmschutzvorrichtungen an Straßen - Nichtakustische Eigenschaften - Teil 1: Mechanische Eigenschaften und Anforderungen an die Standsicherheit
Diese Europäische Norm legt Kriterien für die Klassifizierung von Lärmschutzvorrichtungen an Straßen nach grundlegenden mechanischen Eigenschaften unter Normbeanspruchungsbedingungen fest, unabhängig von den verwendeten Baustoffen. Die Norm enthält eine Reihe von Bedingungen und freigestellten Anforderungen, die die große Vielfalt der Baupraxis in Europa berücksichtigen. Einzelne Aspekte der Eigenschaften werden in den Anhängen behandelt. Sicherheitstechnische Überlegungen im Falle der Beschädigung von Lärmschutzvorrichtungen werden in EN 1794 2 behandelt.
Diese Europäische Norm deckt das derzeitige Verhalten des Produkts ab. Der Beurteilung der langfristigen Eigenschaften sollte EN 14389 2 zugrunde gelegt werden.
ANMERKUNG Das in Anhang A beschriebene Prüfverfahren berücksichtigt keine Ermüdungserscheinungen.
Dispositifs de réduction du bruit du trafic routier - Performances non acoustiques - Partie 1 : Performances mécaniques et exigences en matière de stabilité
La présente Norme européenne spécifie des critères permettant de classer les dispositifs de réduction du bruit dû au trafic routier en fonction de leur performance mécanique fondamentale dans des conditions normales d'exposition, indépendamment des matériaux utilisés. Une gamme de conditions et d'exigences optionnelles est donnée afin de tenir compte de la grande diversité des pratiques en Europe. Chaque aspect des performances est couvert séparément dans les annexes. Les considérations relatives à la sécurité dans le cas de dommages aux dispositifs de réduction du bruit sont couvertes par l’EN 1794-2.
La présente Norme européenne couvre le comportement actuel du produit. Afin d'évaluer ses performances à long terme, la norme EN 14389-2 devrait être utilisée.
NOTE La procédure d’essai décrite en annexe A ne prend pas en compte l’effet de la fatigue.
Protihrupne ovire za cestni promet - Neakustične lastnosti - 1. del: Mehanske lastnosti in zahteve za stabilnost
Ta evropski standard določa merila za kategorizacijo protihrupnih ovir za cestni promet v skladu z osnovnimi mehanskimi lastnostmi pri običajnih pogojih izpostavljenosti, ne glede na uporabljene materiale. Zaradi upoštevanja različnih praks v evropskih državah so podani številni pogoji in izbirne zahteve. Posamezni vidiki lastnosti so ločeno obravnavani v dodatkih. Varnostna tveganja v primeru poškodb protihrupnih ovir za cestni promet so obravnavana v 2. delu tega evropskega standarda.
Ta evropski standard opisuje trenutno funkcijo izdelka. Za ocenitev dolgoročnih lastnosti je treba uporabljati standard EN 14389-2.
