(Main)Liquid pumps and pump units - Noise test code - Grades 2 and 3 of accuracy (ISO 20361:2007)
Liquid pumps and pump units - Noise test code - Grades 2 and 3 of accuracy (ISO 20361:2007)
ISO 20361:2007 specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the airborne noise emission of liquid pumps or pump units. It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test.
The use of ISO 20361:2007 ensures the reproducibility of the determination of the airborne noise-emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement methods according to ISO 20361:2006 are engineering methods (grade 2) and survey methods (grade 3).
ISO 20361:2007 does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps.
Flüssigkeitspumpen und -pumpenaggregate - Geräuschmessung - Genauigkeitsklassen 2 und 3 (ISO 20361:2007)
Diese Internationale Norm legt alle Informationen fest, um wirkungsvoll und unter genormten Bedingungen die
Bestimmung, Angabe und Feststellung der Übereinstimmung der Luftschallgeräuschemission von Flüssigkeitspumpen
oder -pumpenaggregaten durchzuführen (siehe 4.1). Sie legt die zugelassenen Geräuschmessverfahren
und die Betriebs- und Montagebedingungen fest, die zur Prüfung verwendet werden müssen.
Die Geräuschemissions-Kennwerte schließen den Emissionsschalldruckpegel einer festgelegten Position und
den Schalleistungspegel ein. Die Bestimmung dieser Größen ist erforderlich für:
die Angabe der Geräusch-Emissionswerte;
die Lärmminderung an der Quelle in der Konstruktionsphase.
ANMERKUNG 1 Die Bestimmung dieser Größen ist auch für den Vergleich der Geräuschemission in den Verkehr
gebrachter Flüssigkeitspumpen erforderlich.
Die Anwendung dieser Internationalen Norm stellt die Reproduzierbarkeit der Bestimmung von Luftschallgeräuschemissionskennwerten
innerhalb der festgelegten Grenzen der Genauigkeitsklasse des verwendeten
Luftschallgeräuschmessverfahrens sicher. Geräuschmessverfahren nach dieser Internationalen Norm sind
Genauigkeitsklasse 2 (en "Engineering methods") und Genauigkeitsklasse 3 (en "Survey methods").
Diese Internationale Norm behandelt nicht den von Flüssigkeitspumpen erzeugten Körperschall und Flüssigkeitsschall.
ANMERKUNG 2 Diese Internationale Norm dient der Vervollständigung von EN 809, Pumps and pump units for liquids —
Common safety requirements.
Pompes et groupes motopompes pour liquides - Code d'essai acoustique - Classes de précision 2 et 3 (ISO 20361:2007)
L'ISO 20361:2007 spécifie toutes les informations nécessaires pour réaliser efficacement et dans les conditions normalisées, la détermination, la déclaration et la vérification de l'émission de bruit aérien des pompes ou groupes motopompes pour liquides. Elle spécifie également les méthodes de mesurage du bruit ainsi que les conditions de fonctionnement et de montage qui doivent être utilisées pour l'essai.
L'utilisation de l'ISO 20361:2007 assure la reproductibilité de la détermination des caractéristiques d'émission de bruit aérien dans des limites spécifiées, déterminées par la classe de précision de la méthode de base de mesurage du bruit aérien utilisée. Les méthodes de mesurage du bruit selon l'ISO 20361:2007 sont des méthodes d'expertise (classe 2) et des méthodes de contrôle (classe 3).
L'ISO 20361:2007 ne traite pas de la caractérisation du bruit solidien ni du bruit liquidien générés par les pompes pour liquides.
