General Information
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.

Die Norm SIST EN 16951-2:2018 ist ein entscheidendes Dokument im Bereich der Schienenanwendungen, insbesondere in Bezug auf Lärmschutzwände und verwandte Einrichtungen, die auf die Ausbreitung von Luftschall wirken. Der Fokus dieser europäischen Norm liegt auf den nicht-akustischen Eigenschaften, die zur Beurteilung der langfristigen Leistung dieser Lärmschutzvorrichtungen herangezogen werden. Ein bedeutender Stärke der Norm ist die klare Definition der Anforderungen zur Bewertung der Lebensdauer, die unter Berücksichtigung relevanter Expositionsbedingungen erfolgen muss. Die Norm deckt eine Vielzahl von Einflussfaktoren ab, die die Materialien und Konstruktionen betreffen können. Dazu gehören chemische Agentien, Tausalz, Schmutzwasser, Frost-Tau-Zyklen sowie Temperatureffekte, was die umfassende und praxisnahe Anwendbarkeit der Norm unterstreicht. Die Berücksichtigung biogener Prozesse und verschiedener Umweltfaktoren, wie UV-Strahlung und Ozon, zeigt die Relevanz dieser Norm im Kontext von zunehmenden Umweltanforderungen und der Notwendigkeit, langlebige Materialien zu verwenden. Ferner wird der Einfluss von Verkehrsvibrationen auf die Strukturen thematisiert, was in einer Zeit, in der der Schienenverkehr und die Lärmminderung von großer Bedeutung sind, besonders relevant ist. Zusammenfassend lässt sich feststellen, dass SIST EN 16951-2:2018 eine solide Grundlage für die Bewertung der nicht-akustischen Eigenschaften von Lärmschutzwänden bietet und durch die Berücksichtigung unterschiedlicher klimatischer und örtlicher Bedingungen eine umfassende und realitätsnahe Anleitung zur Gewährleistung der langfristigen Funktionalität der verwendeten Materialien darstellt.
The SIST EN 16951-2:2018 standard provides a comprehensive framework for assessing the long-term performance of railway noise barriers and related devices that influence airborne sound propagation. Its primary focus on non-acoustic characteristics is crucial for the construction and evaluation of these noise barriers under varying environmental conditions. One of the significant strengths of this standard is its detailed outline of the requirements for assessing working life, which ensures that materials used in noise barriers remain effective over time. The inclusion of specific exposure conditions encompasses a wide range of factors, such as chemical agents, de-icing salts, and biological processes. This thorough scope allows for a nuanced approach to evaluating the durability and functionality of noise mitigation measures on railway tracks. Moreover, the standard emphasizes location and climate-dependent factors that affect the resilience of materials. By incorporating variability in environmental conditions-such as freeze/thaw cycles, UV radiation, and traffic vibration-it highlights the necessity for tailored assessments based on the barriers' installation sites. This targeted approach ensures that noise barriers can withstand the specific challenges they will face, making the standard particularly relevant for both manufacturers and engineers involved in railway projects. In conclusion, SIST EN 16951-2:2018 stands out for its rigorous methodology and comprehensive coverage of factors affecting the non-acoustic performance of railway noise barriers. By acknowledging the diverse conditions that these barriers must endure, the standard serves as a vital reference point for improving the effectiveness and longevity of sound mitigation strategies in railway applications.

SIST EN 16951-2:2018의 강점 중 하나는 다양한 환경적 요인에 대한 저항성을 평가하기 위한 구체적인 기준을 설정하고 있다는 점입니다. 예를 들어, 화학 물질, 제빙염, 더러운 물 및 먼지와 같은 요인들은 위치와 기후에 따라 달라지는 특성을 가지고 있어, 이를 반영한 평가가 가능하다는 점에서 매우 유용합니다. 이러한 평가 기준은 실제 상황에서의 내구성을 입증할 수 있는 근거자료를 제공하여, 건설 현장에서 적용될 수 있는 신뢰성 높은 결과를 도출할 수 있습니다. 또한, SIST EN 16951-2:2018은 기후에 따라 영향을 받을 수 있는 여러 가지 조건들, 즉 이슬, 동결-해동, 추위 및 열에 대한 저항성을 포함하여 다양한 환경 조건이 소음 장벽의 성능에 미치는 영향을 체계적으로 분석합니다. 이러한 점은 프로젝트의 지속 가능성과 효율성을 증대시키는 데 큰 기여를 할 수 있습니다. 이 표준의 관련성은 오늘날 환경 문제와 소음 문제 해결에 대한 사회적 요구가 높아짐에 따라 더욱 강조됩니다. 철도 인프라 개발에서 소음 저감 기술이 중요한 역할을 수행하고 있음을 고려할 때, SIST EN 16951-2:2018이 제공하는 명확한 기준 및 절차는 안전하고 효과적인 소음 차단 솔루션을 구현하는 데 필수적입니다.
La norme SIST EN 16951-2:2018 établit des exigences précises pour l'évaluation de la durée de vie des barrières anti-bruit et des dispositifs associés agissant sur la propagation du son aérien dans le domaine des applications ferroviaires. Son champ d'application étant clairement défini, elle permet de s'assurer que les équipements répondent aux conditions d'exposition pertinentes tout en garantissant une performance à long terme. Parmi ses atouts majeurs, cette norme aborde les caractéristiques non acoustiques des dispositifs de protection contre le bruit. Elle prévoit une série de tests de matériaux et des constructions nécessaires pour évaluer la résistance aux agents chimiques, aux sels de déneigement, aux eaux sales, à l'humidité et aux variations climatiques telles que le gel et le dégel, la chaleur, ainsi que l'exposition aux radiations UV. Cette approche intégrée garantit que les barrières sont non seulement efficaces dans leur fonction principale, mais aussi durables face aux défis environnementaux spécifiques. La standardisation de ces exigences est particulièrement pertinente dans le contexte actuel où la pollution sonore devient un enjeu majeur dans les zones urbaines. La norme répond ainsi à un besoin croissant de solutions efficaces et durables pour contrôler le bruit ferroviaire, en tenant compte des différentes conditions climatiques et de l'impact potentiel des éléments biologiques ou de l'ozone. En somme, la SIST EN 16951-2:2018 constitue un document fondamental pour le secteur ferroviaire, car elle offre un cadre rigoureux pour l'évaluation des barrières anti-bruit, garantissant ainsi la sécurité et la satisfaction des exigences environnementales dans le cadre de la construction et de l'entretien des infrastructures ferroviaires.
