Ta evropski standard opisuje osnovne zahteve za preverjanje končnih in mejnih stanj uporabnosti ter odpornosti proti utrujanju protihrupne ovire ali njenih komponent z uporabo analitičnih metod in/ali preskusov.
Analitične metode je mogoče uporabljati za ugotavljanje karakterističnih in konstrukcijskih vrednosti.
Če ni na voljo dovolj informacij, je analitični postopek dovoljeno združiti z rezultati preskusov.
Uporabljata se lahko naslednji vrsti preskusnih postopkov:
– preskušanje majhnih vzorcev za določanje kategorij podrobnosti, ki morda niso obravnavane v evrokodih (postopek preverjanja A, podan v tem evropskem standardu);
– splošno preskušanje za določanje mejnega stanja utrujanja (postopek preverjanja B, podan v tem evropskem standardu).
Za potrditev domnev konstrukcijskega modela je treba izvesti preskus statične obremenitve komponent v skladu s standardom prEN 16727-1.
Odpornost proti utrujanju komponent protihrupne ovire je mogoče določiti tudi za opredeljene pogoje obremenitve z izvedbo preskusov polnega obsega pri določeni reprezentativni obremenitvi (postopek preverjanja C, podan v tem standardu).

Overview
EN 16727-2-1:2018 (CEN) specifies the basic requirements for verifying the mechanical performance and resistance to fatigue of railway noise barriers and related devices acting on airborne sound propagation. The standard covers verification of ultimate and serviceability limit states and fatigue resistance of whole barriers or individual components under dynamic loadings due to passing trains. Verification may be achieved by analytical methods, tests, or a combination of both.
Key topics and requirements
- Scope: Applies to noise barrier panels, claddings, acoustic and structural elements, and added devices exposed to transient air pressure waves from passing trains.
- Analytical verification: Encourages use of relevant Eurocodes (EN 1990–1999 series) and European Assessment Documents for foundations, posts and panels; addresses combined actions (bending, shear, torsion), fastener behaviour and material combinations.
- Test procedures: Defines three verification procedures:
- Procedure A - small-sample tests to define detail categories not covered by Eurocodes (e.g., joints, coatings). Requires fatigue testing (example: N = 5×10^6 cycles).
- Procedure B - global element tests to define fatigue limit states of an assembled component or panel.
- Procedure C - full-scale representative loading tests as an alternative to A and B for determining fatigue resistance under defined site-like conditions.
- Test requirements: Pre-test information (design life, train speeds, spacing to track, materials, drawings), deformation-controlled static tests per EN 16727-1 to validate structural models, strain gauge instrumentation, load arrangement representative of aerodynamic pressure waves, and guidance on aged vs. new samples.
- Evaluation: Procedures for deriving characteristic and design fatigue values, S‑N curve determination, and statistical treatment of results (confidence intervals) are provided or referenced.
Practical applications and users
Who uses EN 16727-2-1:2018:
- Structural and acoustic engineers designing railway noise barriers
- Manufacturers and fabricators validating component fatigue life
- Testing laboratories performing fatigue and full-scale structural tests
- Railway infrastructure owners, procurers and certifying bodies specifying durability and safety criteria
- Consultants preparing design reports that combine analytical verification with test evidence
Typical uses:
- Specifying fatigue testing protocols for new barrier systems
- Supporting CE marking / technical assessment and procurement specifications
- Assessing retrofit measures, material changes or novel barrier details
- Verifying long-term serviceability and safety for installations near high-speed lines
