Railway applications - Infrastructure - Noise barriers and related devices acting on airborne sound propagation - Test method for determining the acoustic performance - Part 1: Intrinsic characteristics - Sound absorption under diffuse sound field conditions

This European Standard specifies the laboratory method for measuring the sound absorption performance of railway noise barriers and related devices acting on airborne sound propagation in reverberant conditions. It covers the assessment of the intrinsic sound absorption performance of devices that can reasonably be assembled inside the testing facility described in EN ISO 354.
This method is not intended for the determination of the intrinsic characteristics of sound absorption of noise barriers and related devices acting on airborne sound propagation to be installed on railways in non-reverberant conditions.
The test method in EN ISO 354 referred to in this European Standard excludes devices that act as weakly damped resonators. Some devices will depart significantly from these requirements and in these cases, care is needed in interpreting the results.

Bahnanwendungen - Oberbau - Lärmschutzwände und verwandte Vorrichtungen zur Beeinflussung der Luftschallausbreitung - Prüfverfahren zur Bestimmung der akustischen Eigenschaften - Teil 1: Produktspezifische Merkmale - Schallabsorption (Labormethode) bei diffusen Schallfeldern

Dieses Dokument legt die Labormethode zur Messung der Schallabsorptionsfähigkeit von Lärmschutzwänden für Eisenbahnen und verwandten Vorrichtungen zur Beeinflussung der Luftschallausbreitung unter halligen Bedingungen fest. Sie beinhaltet die Bewertung der produktspezifischen Merkmale von Vorrichtungen gegen Schallübertragung, die in den Prüfeinrichtungen nach EN ISO 354 untersucht werden können.
Dieses Verfahren ist nicht für die Bestimmung der produktspezifischen Eigenschaften der Schallabsorption von Lärmschutzwänden und verwandten Vorrichtungen zur Beeinflussung der Luftschallausbreitung bestimmt, die für Schienenwege unter nicht halligen Bedingungen zu installieren sind.
Die Prüfmethode nach EN ISO 354, auf die in diesem Dokument verwiesen wird, schließt Vorrichtungen aus, die als schwach bedämpfte Resonatoren wirken. Allerdings weichen einige Vorrichtungen bedeutsam von diesen Anforderungen ab, die Bewertung der Ergebnisse kann nicht eindeutig sein.

Applications ferroviaires - Infrastructure - Dispositifs de réduction du bruit - Méthode d'essai pour la détermination des performances acoustique - Partie 1: Caractéristique intrinsèques - Absorption acoustique dans des conditions de champ acoustique diffus

Le présent document définit la méthode en salle réverbérante permettant de mesurer les performances d'absorption acoustique des dispositifs de réduction du bruit dans des conditions de champ réverbéré. Il couvre l'évaluation des performances intrinsèques d'absorption acoustique des dispositifs qui peuvent raisonnablement être assemblés à l'intérieur du local d'essai décrit dans l'EN ISO 354.
La présente méthode n'est pas destinée à déterminer les caractéristiques intrinsèques de l'absorption acoustique des dispositifs de réduction du bruit destinés à être installés sur des voies ferrées en conditions de champ non réverbéré.
La méthode d'essai de l'EN ISO 354 référencée dans le présent document exclut les dispositifs qui agissent comme des résonateurs faiblement amortis. Comme certains dispositifs s'écartent de ces exigences, l'interprétation des résultats peut alors être difficile.

Railway applications - Infrastructure - Mechanical requirements for joints in running rails
SIST EN 16843:2024

This European Standard deals with mechanical rail joints for flat bottom rails 46 kg/m and over. The scope of this standard is: to
establish requirements for insulated and non-insulated rail joints, for stressed rail (continuous welded rail, CWR) and unstressed rail (jointed track); to define mechanical and electrical requirements for type approval and for acceptance of insulated rail joints which are manufactured in a factory (prefab construction) as well as assembled onsite (site construction). This standard specifies the minimum requirements. Special applications as for instance tram systems may require different demands in certain paragraphs and should be agreed between customer and supplier. The scope also excludes expansion joints (it is covered in EN 13232-8), and special joints in switch constructions.

Railway applications - Infrastructure - Noise barriers and related devices acting on airborne sound propagation - Test method for determining the acoustic performance - Part 5: Intrinsic characteristics - Sound absorption under direct sound field conditions
SIST EN 16272-5:2024

This document describes a test method for measuring a quantity representative of the intrinsic characteristics of sound absorption from railway noise barriers and related devices acting on airborne sound propagation, the sound reflection index RI, and then calculate a single-number rating for sound absorption from it.
The test method is intended for the following applications:
-   determination of the intrinsic characteristics of sound absorption of noise barriers and related devices acting on airborne sound propagation to be installed along railways, to be measured either on typical installations alongside railways or on a relevant sample section;
-   determination of the intrinsic characteristics of sound absorption of noise barriers and related devices acting on airborne sound propagation in actual use under direct sound field conditions;
-   comparison of design specifications with actual performance data after the completion of the construction work;
-   verification of the long-term performance of noise barriers and related devices acting on airborne sound propagation (with a repeated application of the method).
The test method is not intended for the following applications:
-   determination of the intrinsic characteristics of sound absorption of noise barriers and related devices acting on airborne sound propagation to be installed in reverberant conditions, e.g. inside tunnels or deep trenches.
Results for the sound reflection index are expressed as a function of frequency, in one-third octave bands, where possible, between 100 Hz and 5 kHz. If it is not possible to get valid measurements results over the whole frequency range indicated, the results are given in a restricted frequency range and the reasons of the restriction(s) are clearly reported.

This document applies to urban or suburban rail networks for passenger services not integrated with the national network.
Sections of urban or suburban rail networks integrated in the national rail networks are not covered by this document. They are covered by EN 13803 (or for nominal track gauges smaller than 1 435 mm by national alignment rules).
For the purpose of this document, urban or suburban rail networks include:
-   Networks designed for own right of way and segregated from general road and pedestrian traffic,
and
-   Networks (partly) not segregated from general road and pedestrian traffic, with shared lanes.
This document applies to rail systems with steel wheels running on steel vignole or grooved rails. Rail systems with specific construction issues (e.g. rack railways, funicular railways and other types of cable drawn rail systems) are not covered by this document.
This document defines the parameters, rules and limits for nominal track gauges of 1 435 mm and 1 000 mm with permissible speeds up to 120 km/h. For other nominal track gauges, this document defines conversion rules which shall be used to define the limits.
