适用范围：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 dependent Ⅱ. De-icing salt Location/climate Dependent Ⅲ. Dirty water/dust Location/ Climate dependent Ⅳ. Dew Climate dependent Ⅴ. Freeze/thaw Climate dependent Ⅵ. Cold Climate dependent Ⅶ. Heat Climate dependent Ⅷ. UV Radiation Climate dependent Ⅸ. Traffic Vibration Location dependent Ⅹ. Biological Process Climate dependent Ⅺ. Ozone Location dependent Ⅻ. Water Climate dependent ⅩⅢ. Water spray Location Wet/dry dependent
