What is BS EN 16951-2 - Non-acoustic characteristics of noise barriers in railway application about?
BS EN 16951-2 discusses non-acoustic characteristics of railway applications. BS EN 16951-2 specifies requirements for assessing working life and providing the relevant exposure conditions.
Standards of construction and any material tests conducted should provide evidence of resistance to specified conditions selected from the following:
- Chemical Agents Location dependent
- De-icing salt Location/climate-dependent
- Dirty water/dust Location/Climate dependent
- Dew Climate dependent
- Freeze/thaw Climate dependent
- Cold Climate dependent
- Heat Climate dependent
- Ultra-Violet (UV) Radiation Climate dependent
- Traffic Vibration Location dependent
- Biological Process Climate dependent
- Ozone Location dependent
- Water Climate dependent
- Water spray
Wet/dry Location dependent
Who is BS EN 16951-2 - Non-acoustic characteristics of noise barriers in railway application for?
BS EN 16951-2 on railway applications – non-acoustic characteristics is useful for:
- Manufacturers and suppliers of noise barriers used in railway applications
- Railway authorities
- Railway engineer
- Mechanical engineers
- Operators
Why should you use BS EN 16951-2 - Non-acoustic characteristics of noise barriers in railway application?
BS EN 16951-2 specifies non-acoustic characteristics of railway applications that obstruct the direct transmission of airborne sound emanating from railways, and which will typically span between posts and also may overhang the railway.
The non-acoustic characteristics of noise barriers and related devices acting on sound propagation can deteriorate significantly over the duration of their working life. To reduce this BS EN 16951-2 specifies requirements for assessing the working life and provides the relevant exposure conditions.
Noise barriers and related devices acting on airborne sound propagation installed along railways should not pose hazards to rail users or other people in the vicinity or to the environment at large. BS EN 16951-2 helps to minimize risk to adjacent premises, or to rail users in confined corridors.
