Liquid pumps and pumps units - Noise test code - Grades 2 and 3 of accuracy (ISO 20361:2019)
This document 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 (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test.
Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities is necessary for
— declaring the noise emission values, and
— purpose of noise control at source at the design stage.
The determination of these quantities is also necessary for comparing the noise emitted by liquid pumps on the market.
The use of this document 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 this document are engineering methods (grade 2) and survey methods (grade 3).
This document does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps.
NOTE This document is specified in EN 809+A1 for noise measurements of the pump (or pump unit).
Flüssigkeitspumpen und -pumpenaggregate - Geräuschmessung - Genauigkeitsklassen 2 und 3 (ISO 20361:2019)
Dieses Dokument 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). Es legt die zugelassenen Geräuschmessverfahren und die Betriebs- und Montagebedingungen fest, die zur Prüfung verwendet werden müssen.
Die Geräuschemissionskennwerte schließen den Emissionsschalldruckpegel an einer festgelegten Position und den Schallleistungspegel ein. Die Bestimmung dieser Größen ist erforderlich für:
- die Angabe der Geräuschemissionswerte und
- den ursachenbezogenen Lärmschutz in der Konstruktionsphase.
Die Bestimmung dieser Größen ist auch für den Vergleich der Geräuschemission in Verkehr gebrachter Flüssigkeitspumpen erforderlich.
Die Anwendung dieses Dokuments stellt die Reproduzierbarkeit der Bestimmung von Luftschallgeräuschemissionskennwerten innerhalb der festgelegten Grenzen der Genauigkeitsklasse des verwendeten Luftschallgeräuschmessverfahrens sicher. Geräuschmessverfahren nach diesem Dokument sind Genauigkeitsklasse 2 (en: „engineering method“) und Genauigkeitsklasse 3 (en: „survey method“).
Dieses Dokument behandelt nicht die Analyseverfahren des von Flüssigkeitspumpen erzeugten Körper- und Flüssigkeitsschalls.
ANMERKUNG Dieses Dokument ist in EN 809+A1 für Schallmessungen der Pumpe (oder des Pumpenaggregats) angegeben.
Pompes et groupes motopompes pour liquides - Code d'essai acoustique - Classes de précision 2 et 3 (ISO 20361:2019)
Le présent document 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 (voir 4.1). Elle spécifie également les méthodes de mesure du bruit ainsi que les conditions de fonctionnement et de montage qui doivent être utilisées pour l'essai.
Les caractéristiques d'émission sonore comprennent les niveaux de pression acoustique d'émission en des points spécifiés ainsi que le niveau de puissance acoustique. La détermination de ces grandeurs est nécessaire pour
— déclarer les valeurs d'émission sonore, et
— réduire le bruit à la source au stade de la conception.
La détermination de ces quantités est aussi nécessaire pour comparer le bruit émis par les pompes pour liquides sur le marché.
L'utilisation du présent document 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 mesure du bruit aérien utilisée. Les méthodes de mesure du bruit selon le présent document sont des méthodes d'expertise (classe 2) et des méthodes de contrôle (classe 3).
Le présent document ne traite pas de la caractérisation du bruit solidien ni du bruit liquidien générés par les pompes pour liquides.
NOTE Le présent document est spécifié dans l'EN 809+A1 en ce qui concerne le mesurage du bruit de la pompe (ou du groupe motopompe).
Črpalke za tekočine in črpalni agregati - Preskusni postopki za merjenje hrupa - Razreda točnosti 2 in 3 (ISO 20361:2019)
Ta dokument določa vse potrebne informacije za učinkovito določanje, objavljanje in preverjanje emisij hrupa črpalk za tekočine in črpalnih agregatov, ki bo potekalo pod standardiziranimi pogoji (glej točko 4.1). Določa preskusne postopke za merjenje hrupa ter zahteve za delovanje in priključitev, ki se uporabljajo za preskus. Lastnosti emisij hrupa vključujejo ravni emisij zvočnega tlaka na določenih položajih in raven zvočne moči. Določanje teh količin je potrebno za: – objavljanje vrednosti emisij hrupa; in – namen zvočne zaščite pri viru v fazi projektiranja. Določanje teh količin je prav tako potrebno za primerjavo emisij hrupa različnih črpalk za tekočine na trgu. Uporaba tega dokumenta zagotavlja ponovljivost določanja značilnosti zračnih emisij hrupa v določenih mejah, ki jih določa razred točnosti uporabljene osnovne metode merjenja zračnih emisij hrupa. Metode merjenja hrupa, ki jih določa ta dokument, so inženirske metode (razred 2) in metode raziskovanja (razred 3). Ta dokument ne zajema karakterizacije strukturnega zvoka in vodnega hrupa, ki ju proizvajajo črpalke za tekočine.
