Overview
EN 16951-2:2018 (CEN) specifies procedures for assessing the long-term performance of railway noise barriers and related devices with a focus on non-acoustic characteristics (durability, environmental resistance and structural service life). The standard defines relevant exposure conditions and requirements manufacturers must meet to declare a product’s working life under defined environmental classes. It complements the acoustic test parts of the EN 16951 series and the non-acoustic performance standards used in railway track applications.
Key topics and technical requirements
- Scope: assessment of working life and exposure conditions for noise barriers, claddings and added devices acting on airborne sound propagation.
- Environmental agents (manufacturer to consider):
- Chemical agents, de-icing salt, dirty water/dust, dew, freeze/thaw, cold, heat, UV radiation, traffic vibration, biological processes, ozone, water, water spray.
- Exposure classification: uses selected classes from EN 60721-3-4 and Annex A of EN 16951-2 to assign rail-side environmental categories (e.g., 4K, 4B, 4C, 4Z).
- Design & materials: structural elements must comply with appropriate Eurocode requirements; materials and construction standards should provide evidence of resistance to selected exposure conditions.
- Manufacturer obligations:
- List measures taken to limit ageing and interactions between different materials (electrolytic/chemical corrosion).
- Declare working life per exposure class and for both structural and acoustic elements (working life is the minimum of component lives).
- Provide installation and maintenance manuals specifying how to achieve declared working life.
- Reporting requirements: full product description, material details, drawings, list of ageing mitigation measures, declared working life table, installer/maintenance instructions, and independent evaluation body identification.
- Special tests: where maintenance includes high-pressure cleaning, product must withstand a 20 MPa water jet for 10 s at 150 mm on all faces.
Practical applications and users
Who uses EN 16951-2:2018:
- Noise barrier manufacturers - to design and declare durability and provide compliant documentation.
- Railway infrastructure owners / asset managers - to specify procurement requirements, compare product lifetimes, and plan maintenance.
- Design engineers and installers - to ensure structural design (Eurocodes) and installation achieve declared working life.
- Testing laboratories and independent evaluators - to prepare reports and verify manufacturer claims.
- Procurement bodies and specifiers - to include standardized durability criteria in tenders and life-cycle assessments.
