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 to allow for the wide diversity of practice within Europe. Individual aspects of performance are covered separately in the annexes. Safety considerations in the event of damage to noise reducing devices are also covered in Part 2 of this European Standard.
Lärmschutzeinrichtungen an Straßen - Nichtakustische Eigenschaften - Teil 1: Mechanische Eigenschaften und Anforderungen an die Standsicherheit
Diese Europäische Norm enthält Kriterien für die Klassifizierung von Lärmschutzeinrichtungen an Straßen nach grundlegenden mechanischen Eigenschaften unter Normbeanspruchungsbedingungen, unabhängig von den verwendeten Baustoffen. Die Norm enthält eine Reihe von Bedingungen und freigestellten Anforderungen, die die große Vielfalt der Baupraxis in Europa berücksichtigt. Einzelne Beanspruchungsarten werden in den Anhängen behandelt. Sicherheitstechnische Überlegungen im Falle der Beschädigung von Lärmschutzeinrichtungen werden in Teil 2 dieser Europäischen Norm behandelt.
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 du trafic routier en fonction de leur performance mécanique de base 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. Les aspects individuels des performances sont couverts séparément dans les annexes. Les considérations relatives à la sécurité dans le cas de dommages aux dispositifs de réduction du bruit sont également couvertes dans la partie 2 de la présente norme européenne.

They can also besubjected to shocks caused by stones or other debris thrown up by vehicle tyres and, in some countries, thedynamic force of snow ejected by equipment used to clear roads in winter. The deflections of a noise reducingdevice under such loads during its design life should not reduce its effectiveness.
