Railway applications - Gangway systems between vehicles - Part 2: Acoustic measurements
This document specifies a measurement method and conditions to obtain reproducible and comparable sound reduction indices of all kinds of rail bound vehicles’ gangway systems as specified in EN 16286 1. The setup includes all components of the system mounted like this is done between two adjacent car bodies within the train, so that a person will be able to use the gangway system, consisting of e.g.:
— the bridge system (footplate);
— side panels;
— flexible components (bellows);
— mounting systems;
— elements to couple parts in the case of separable gangway systems.
The method is applicable to type testing of gangways.
This method is not applicable to:
— interior noise measurements in vehicles;
— structure borne noise measurements.
The type testing procedures specified in this document are of engineering grade (grade 2) in the frequency range from 100 Hz up to 5 000 Hz.
NOTE This is the preferred range for noise declaration purposes, as specified in EN ISO 12001. If test conditions are relaxed, the results are no longer of engineering grade (grade 2).

Le présent document spécifie une méthode et des conditions de mesurage permettant d'obtenir divers
indices d'affaiblissement acoustiques reproductibles et comparables pour tous les types de systèmes
d'intercirculation entre les véhicules ferroviaires définis dans l’EN 16286-1. L’installation comprend tous
les composants du système de montage ou d’assemblage, comme ceux qui existent pour la mise en place
du système d’intercirculation monté entre deux véhicules ferroviaires d’un même train pour permettre à
une personne d'utiliser le système d'intercirculation, à savoir par exemple :
— la passerelle ;
— les parois verticales ;
— les composants flexibles (soufflets) ;
— les systèmes de montage ;
— les éléments d'accouplement dans le cas de systèmes d'intercirculation séparables.
La méthode s'applique aux essais de type des intercirculations.
La présente méthode ne s'applique pas aux :
— mesurages du bruit à l'intérieur des véhicules ;
— mesurages du bruit solidien.
Les modes opératoires des essais de type spécifiés dans la présente Norme européenne sont de classe
expertise (classe 2) dans le domaine de fréquences de 100 Hz à 5 000 Hz.
NOTE il s'agit du domaine de fréquence recommandé pour la déclaration de bruit, telle que définie dans
l’EN ISO 12001. Si les conditions d'essai sont moins strictes, les résultats ne sont plus de classe expertise (classe 2).
Železniške naprave - Prehodni sistemi med vozili - 2. del: Meritve akustike
Ta dokument določa merilno metodo in pogoje za pridobivanje ponovljivih in primerljivih indeksov zvočne izolirnosti vseh vrst prehodnih sistemov železniških vozil, kot je določeno v standardu EN 16286 1. Vsi sestavni deli sistema morajo biti nameščeni na način, ki združuje dve sosednji ogrodji vagona v okviru vlaka, da lahko oseba uporablja prehodni sistem, ki vključuje npr.:
– mostni sistem (ploščad);
– stranske plošče;
– upogljive sestavne dele (mehovi);
– montažne sisteme;
– elemente za spojitev delov v primeru ločljivih prehodnih sistemov.
Metoda se uporablja za tipske preskuse prehodnih sistemov.
Ta metoda se ne uporablja za:
– merjenje hrupa v vozilih;
– merjenje hrupa, ki ga povzročajo strukture.
Postopki preskušanja tipa, določeni v tem dokumentu, so postopki inženirskega razreda (razred 2) v frekvenčnem razponu od 100 Hz do 5000 Hz.
OPOMBA: To je prednostni razpon za namene objave podatkov o hrupu, kot je opredeljeno v standardu EN ISO 12001. Če so preskusni pogoji manj strogi, rezultati niso več inženirskega razreda (razred 2).

Introduction
This document presents a measurement method to collect information about the noise insulation of rail
bound vehicle gangway systems. These components need their own measurement procedure as the
geometrical sound distribution situation is not in line with the basic assumptions of general standards
about noise insulation measurements as provided for building elements, etc.
In this document, a number of different setups are described, which represent possible approaches to
the ideal test situation. As the approaches can contradict the ideal sound fields, the document includes
methods to assess the influence of reflections and other difficulties in order to reduce the uncertainties
of these test methods to an acceptable amount in Annex A.
1 Scope
This document specifies a measurement method and conditions to obtain reproducible and comparable
sound reduction indices of all kinds of rail bound vehicles’ gangway systems as specified in EN 16286-1.
The setup includes all components of the system mounted like this is done between two adjacent car
bodies within the train, so that a person will be able to use the gangway system, consisting of e.g.:
— the bridge system (footplate);
— side panels;
— flexible components (bellows);
— mounting systems;
— elements to couple parts in the case of separable gangway systems.
The method is applicable to type testing of gangways.
This method is not applicable to:
— interior noise measurements in vehicles;
— structure borne noise measurements.
The type testing procedures specified in this document are of engineering grade (grade 2) in the
frequency range from 100 Hz up to 5 000 Hz.
NOTE This is the preferred range for noise declaration purposes, as specified in EN ISO 12001. If test
conditions are relaxed, the results are no longer of engineering grade (grade 2).
