Railway applications - Noise emission - Rail roughness measurement related to rolling noise generation

1.1 This European Standard specifies a direct method for characterizing the surface roughness of the rail
associated with rolling noise ("acoustic roughness"), in the form of a one-third octave band spectrum.
This standard describes a method for:
a) selecting measuring positions;
b) data acquisition;
c) measurement data processing in order to estimate a set of one-third octave band roughness spectra;
d) presentation of this estimate for comparison with limits of acoustic roughness;
e) comparison with a given upper limit in terms of a one-third octave band wavelength spectrum.
1.2 It is applicable to the:
a) performance testing of reference track sections for the measurement, within a period of three months
before or after roughness characterization, of noise emitted by railway vehicles for acceptance testing
purposes;
b) acceptance of the rail surface condition only in the case where the result of the direct measurement of the
acoustic roughness is regarded as an established acceptance criterion.
1.3 It is not applicable to the:
a) measurement of rail roughness using an indirect method;
b) measurement of combined wheel-rail roughness;
c) analysis of the effect of wheel-rail interaction, such as a “contact filter”;
d) approval of rail reprofiling, including rail grinding operations, except for those where the acoustic
roughness (and not the level of corrugation) is an established approval criterion;
e) characterization of track geometry.
Testing and approval of measuring apparatus are not part of the scope of this standard.

Bahnanwendungen - Geräuschemission - Messung der Schienenrauheit im Hinblick auf die Entstehung von Rollgeräusch

Diese Europäische Norm legt ein direktes Verfahren zur Charakterisierung der Rauheit der Schienenfahrfläche
im Hinblick auf das Rollgeräusch fest (akustische Rauheit), dargestellt in Form eines Terzspektrums.
Die vorliegende Norm gibt ein Verfahren an
- zur Auswahl der Messpositionen,
- zur Messwerterfassung,
- zur Verarbeitung der Messwerte, mit dem Ziel ein Rauheits-Terzspektrum abzuschätzen,
- zur Darstellung der Ergebnisse zum Vergleich mit einer Grenzkurve für die akustische Rauheit,
- zur Bewertung in Bezug auf eine obere Grenzkurve, die als Terzspektrum über der Wellenlänge
vorgegeben ist.
Sie ist anwendbar
- zur Güteprüfung von Referenz-Gleisabschnitten, auf denen im Rahmen der Abnahmeprüfung der Fahrzeuge
(Typprüfung) innerhalb von drei Monaten Messungen der Schallemissionen von Schienenfahrzeugen
durchgeführt werden,
- zur Abnahmeprüfung der Schienenfahrflächen-Qualität, sofern das direkte Messergebnis der akustischen
Rauheit ein vereinbartes Abnahmekriterium ist.
Sie ist nicht anwendbar
- zur Messung der Schienenrauheit mittels eines indirekten Verfahrens,
- zur Messung der kombinierten Rad-Schiene-Rauheit,
- zur Analyse der Auswirkungen der Rad-Schiene-Wechselwirkung, wie etwa der Filterwirkung des Rad-
Schiene-Kontakts,
- zur Abnahmeprüfung der Schienenfahrflächen-Qualität nach erfolgter Reprofilierung, einschließlich
Schienenschleifen, es sei denn, die akustische Rauheit (nicht die Riffel) ist ein vereinbartes Abnahmekriterium,
- zur Beschreibung der Gleisgeometrie.
Prüfung und Zulassung der Messgeräte werden in dieser Norm nicht behandelt.

Applications ferroviaires - Emission de bruit - Mesurage de la rugosité des rails relative à la génération du bruit de roulement

La présente norme européenne spécifie une méthode directe de caractérisation de la rugosité de la surface du rail associée au bruit de roulement (« rugosité acoustique »), sous la forme d’un spectre par bandes de tiers d’octave.
Ce document présente une méthode pour :
-   la sélection des positions de mesurage,
-   l’acquisition de données,
-   le traitement des données de mesurage de façon à estimer un jeu de spectres de rugosité par bandes de tiers d’octave,
-   la présentation de ces estimations pour la comparaison avec des limites de rugosité acoustique,
-   la comparaison avec une limite supérieure donnée, en termes de spectre de longueurs d’ondes par bandes de tiers d’octave.
Il est applicable pour :
-   le test des performances de sections de voies de référence pour le mesurage, réalisé dans une période de trois mois sur cette voie, du bruit émis par les véhicules ferroviaires, dans le cadre d’essais de réception,
-   la réception de la qualité de surface des rails, seulement dans le cas où le résultat de la mesure directe de la rugosité acoustique est considéré comme un critère de réception établi.
Il n’est pas applicable :
-   au mesurage de la rugosité du rail par une méthode indirecte,
-   au mesurage de la rugosité combinée roue-rail,
-   à l’analyse de l’effet de l’interaction roue-rail comme celle du filtre de contact,
-   à la réception d’opérations de reprofilage de rails incluant le meulage, à l’exception de celles où la rugosité acoustique (et non l’usure ondulatoire) est un critère établi de réception,
-   à la caractérisation de la géométrie de la voie.
Les essais et l’homologation des appareils de mesurage ne sont pas du domaine d’application de cette norme.
