Road traffic noise reducing devices - Procedures for assessing long term performance - Part 2: Non-acoustical characteristics
This document specifies assumed working life requirements and is also intended to assist suppliers in its prediction.It is to be used only for devices manufactured from materials covered by documents which allow prediction of working life (see Annex B). Materials excepted are those which do not affect the non acoustic performance of the device required by EN 1794 parts 1 and 2.Standards of construction and any material tests conducted should provide evidence of resistance to specified conditions selected from the following:I. Chemical Agents Location dependentII. De-icing salt Location/ climate DependentIII. Dirty water/ dust Location/ Climate dependentIV. Dew Climate dependentV. Freeze/ thaw Climate dependentVI. Cold Climate dependentVII. Heat Climate dependentVIII. UV Radiation Climate dependentIX. Traffic Vibration Location dependentX. Biological Process Climate dependentXI. Ozone Location dependentXII. Water Climate dependentXIII. Water spray Location Wet/ dry dependent dependentIV. Dew Climate dependentV. Freeze/ thaw Climate dependentVI. Cold Climate dependentVII. Heat Climate dependentVIII.
