scope:

This European Standard specifies requirements for assessing the working life and provides the relevant exposure conditions.

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 (Wet/dry) Location dependent

NOTE Special care is taken for combinations of different materials, whether inside a single device or in combination with other devices (for example: a combination of different acoustic elements or another combination of acoustic and structural elements).
