BS EN 14389-2:2015

What is BS EN 14389-2- Non-acoustical characteristics of road traffic noise reducing devices about? 

BS EN 14389-2 is a standard that serves technical specifications for non-acoustical characteristics of road traffic noise reducing devices, ensuring long term durability and operability in noise reduction on traffic roads. 

BS EN 14389-2 specifies requirements for assessing the working life and provides the relevant exposure conditions. 

BS EN 14389-2 provides standards of construction and material tests conducted to provide evidence of resistance to specified conditions to be 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 
• UV Radiation - Climate dependent 
• Traffic Vibration - Location dependent 
• Biological Process - Climate dependent 
• Ozone - Location dependent 
• Water - Climate dependent 
• Water spray (Wet/dry) - Location dependent 

Note: Exceptional care is taken for combinations of varied 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). 

Who is BS EN 14389-2- Non-acoustical characteristics of road traffic noise reducing devices for? 

BS EN 14389-2 on non-acoustical characteristics of road traffic noise reducing devices applies to: 

• Manufacturers and suppliers of noise reducing devices 
• Dealers and importers of noise reducing devices 
• Contractors and infrastructure developers 
• Construction, civil and design engineers 
• Road maintenance authorities 
• Inspection and quality assurance services 

Why should you use BS EN 14389-2- Non-acoustical characteristics of road traffic noise reducing devices? 

Noise reducing devices alongside roads should not only fulfil their acoustic function and structural design requirements but also maintain their performance during the required working life. The structural elements need to retain acceptable minimum safety factors at the end of their working life and the acoustic elements not only have to remain effective structurally but provide the specified acoustic performance 

BS EN 14389-2 provides users guidance on requirements for road traffic noise reducing devices, including standard environmental categories with variations and acoustic performance characteristics and long-term performance of the contact with the ground, ensuring stable operability and noise reduction on traffic roads. 

The adoption of BS EN 14389-2 allows users to assess the long-term performance of non-acoustical characteristics in road traffic noise reducing devices, ensuring operational stability, performance, and longevity in traffic road applications. 

What’s changed since the last update? 

BS EN 14389-2:2015 supersedes BS EN 14389-2:2004, which is now withdrawn. 

Changes in BS EN 14389-2:2015 include a new presentation of the requirement to be coherent with the new EN 14389-1. In the latest version, the manufacturer must declare in Table 1 the working life of non-acoustic performances in the function of exposure classes.
