BAS EN 14389-2:2006

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 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
