Acoustics - Railway applications - Measurement of noise emitted by railbound vehicles (ISO 3095:2013)
This International Standard specifies measurement methods and conditions to obtain reproducible and comparable exterior noise emission levels and spectra for all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called ?unit?. This International Standard is applicable to type testing of units. It does not include all the instructions to characterize the noise emission of the other infrastructure related sources (bridges, crossings, switching, impact noise, curving noise, etc.).
Bahnanwendungen - Akustik - Messung der Geräuschemission von spurgebundenen Fahrzeugen (ISO 3095:2013)
Diese Europäische Norm legt die Messverfahren und -bedingungen fest, um reproduzierbare und vergleichbare Außengeräuschpegel und -spektren für alle Arten spurgebundener Fahrzeuge zu gewinnen, die auf Schienen oder anderen Arten fest verlegter Gleise verkehren, hier nachfolgend üblicherweise „Einheit“ genannt.
Diese Norm ist anwendbar für die Typprüfung von Einheiten. Sie umfasst nicht all jene Vorschriften mit denen die Geräuschemission der anderen infrastrukturbezogenen Quellen (Brücken, Bahnübergänge, Weichen, Stoßgeräusche, Kurvengeräusche usw.) bestimmt werden.
Diese Norm ist nicht anwendbar auf
- die Geräuschemission von arbeitenden Gleisbaumaschinen,
- die Beurteilung der Umweltbelastung,
- die Beurteilung der Geräuscheinwirkung,
- das Geräusch der Warnsignale.
Die Ergebnisse können z. B. benutzt werden,
- um das von Zügen abgestrahlte Außengeräusch zu charakterisieren,
- um die Geräuschemission von verschiedenen Einheiten auf einem bestimmten Gleisabschnitt zu vergleichen,
- um grundlegende Quelldaten für Züge zu erheben.
Die für die Typprüfung in dieser Norm festgelegten Verfahren haben die Genauigkeitsklasse 2 (mit Fehler-grenzen von 2 dB), das ist die für die Zwecke der Geräuschangabe bevorzugte Genauigkeitsklasse, wie in EN ISO 12001 bestimmt. Wenn die Prüfbedingungen (z. B. Fahrzeug- und/oder Gleiszustand, Mess-bedingungen) gelockert werden, z. B. um gewöhnliche Züge am Gleis zu überwachen, haben die Ergebnisse folglich nicht mehr die Genauigkeitsklasse 2.
Die für Beschleunigungs- und Bremsprüfungen festgelegten Verfahren haben die Genauigkeitsklasse 3 (siehe EN ISO 12001).
Acoustique - Applications ferroviaires - Mesurage du bruit émis par les véhicules circulant sur rails (ISO 3095:2013)
L'ISO 3095:2013 spécifie la méthode et les conditions de mesurage pour obtenir des niveaux et spectres d'émission de bruit extérieur reproductibles et comparables pour tous les types de véhicules ferroviaires circulant sur des rails ou d'autres types de voie fixe, ci-après appelés par convention «élément».
L'ISO 3095:2013 est applicable à l'essai de type des éléments. Elle n'inclut pas toutes les instructions qui visent à caractériser l'émission de bruit des autres sources liées à l'infrastructure (les ponts, les passages à niveau, les aiguillages, le bruit d'impact, le bruit en courbe, etc.).
L'ISO 3095:2013 n'est pas applicable:
- au bruit à l'émission des éléments de maintenance des voies lors de leurs phases de travail,
- à l'évaluation de l'impact sur l'environnement,
- à l'évaluation de la gêne due au bruit,
- aux bus guidés,
- aux bruits de signaux d'avertissement.
Les résultats peuvent être utilisés, par exemple:
- pour caractériser le bruit extérieur émis par les unités,
- pour comparer l'émission de bruit de divers éléments sur une section de voie particulière,
- pour recueillir des données de source de base pour les trains.
Akustika - Železniške naprave - Merjenje hrupa, ki ga oddajajo tirna vozila (ISO 3095:2013)
Ta mednarodni standard določa merilne metode in pogoje za pridobivanje ponovljivih in primerljivih ravni in spektrov zunanjega hrupa, ki ga oddajajo različna tirna vozila (v nadaljevanju »enota«). Ta mednarodni standard se uporablja za tipsko preskušanje enot. Standard ne vključuje vseh navodil za označevanje hrupa, ki ga oddajajo drugi viri infrastrukture (mostovi, prehodi, stikalna oprema, udarni zvok, zvok pri zavijanju itd.).

Introduction
Railway exterior noise is encountered both along open track and in and around depots, stops, stations
and other holding locations. It includes a number of different physical sources such as rolling noise,
impact noise, traction noise, aerodynamic noise, curving noise, braking noise, horn noise and noise from
auxiliary equipment and other components. The noise for any given train type strongly depends on the
rolling stock design, operating conditions and the track type and condition.
Rolling noise is one of the main sources which contain a significant and sometimes dominant noise
contribution from the track. This International Standard is intended to characterize the noise emission
from the unit, minimizing the influence of the track.

INTERNATIONAL STANDARD ISO 3095:2013(E)
Acoustics — Railway applications — Measurement of noise
emitted by railbound vehicles
1 Scope
This International Standard specifies measurement methods and conditions to obtain reproducible and
comparable exterior noise emission levels and spectra for all kinds of vehicles operating on rails or other
types of fixed track, hereinafter conventionally called “unit”.
This International Standard is applicable to type testing of units. It does not include all the instructions
to characterize the noise emission of the other infrastructure related sources (bridges, crossings,
switching, impact noise, curving noise, etc.).
This International Standard is not applicable to:
— the noise emission of track maintenance units while working;
— environmental impact assessment;
— noise immission assessment;
— guided buses;
— warning signal noise.
The results may be used, for example:
— to characterize the exterior noise emitted by units;
— to compare the noise emission of various units on a particular track section;
— to collect basic source data for units.
NOTE 1 The type testing procedures specified in this International Standard are of engineering grade (grade 2),
that is the preferred one for noise declaration purposes, as defined in ISO 12001. If test conditions (e.g. vehicle
and/or track conditions, measuring conditions) are relaxed (e.g. as done for trackside monitoring of in-service
trains), then the results are no longer of engineering grade.
NOTE 2 The procedures specified for accelerating and decelerating tests are of survey grade, see ISO 12001.
NOTE 3 Additional guidance is provided in Annex D for measurements in the specific case of light rail vehicles.

Introduction
Railway exterior noise is encountered both along open track and in and around railway yards and stations. It
includes a number of different physical sources such as rolling noise, impact noise, traction noise,
aerodynamic noise, curve squeal, braking noise, horn noise and noise from auxiliary equipment and other
components. The noise for any given train type strongly depends on the rolling stock design, operating
conditions and the track type and condition. Some of the typical sources and where they occur are indicated in
Table 1.
Rolling noise is one of the main sources which contains a significant and sometimes dominant noise
contribution from the track. This standard is intended to characterise the noise from the unit, minimising the
influence of the track. For this reason, rail impact noise, bridge noise and curve squeal are not included. Also
noise from trackside warning systems and horns are not included.

1 Scope
This European Standard specifies the measurement method and conditions to obtain reproducible and
comparable exterior noise emission levels and spectra for all kinds of railbound vehicles operating on rails or
other types of fixed track, hereinafter conventionally called “unit”.
This standard is applicable to type testing of units. It does not include all the instructions to characterize the
noise emission of the other infrastructure related sources (bridges, crossings, switching
