Liquid pumps and pump units - Noise test code - Grades 2 and 3 of accuracy (ISO 20361:2015)
ISO 20361:2015 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.
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 ISO 20361:2015 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 20361:2015 are engineering methods (grade 2) and survey methods (grade 3).
ISO 20361:2015 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 20361:2015)
Diese Internationale Norm legt alle Informationen fest, um wirkungsvoll und unter genormten Bedingungen die Bestimmung, Angabe und Feststellung der Übereinstimmung der Luftschallgeräuschemission von Flüssig¬keitspumpen oder -pumpenaggregaten durchzuführen (siehe 4.1). Sie legt die zugelassenen Geräuschmess¬verfahren 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;
den ursachenbezogenen Lärmschutz in der Konstruktionsphase.
ANMERKUNG 1 Die Bestimmung dieser Größen ist auch für den Vergleich der Geräuschemission in Verkehr gebrachter Flüssigkeitspumpen erforderlich.
Die Anwendung dieser Internationalen Norm stellt die Reproduzierbarkeit der Bestimmung von Luftschall¬geräuschemissionskennwerten innerhalb der festgelegten Grenzen der Genauigkeitsklasse des verwendeten Luftschallgeräuschmessverfahrens sicher. Geräuschmessverfahren nach dieser Internationalen Norm sind Genauigkeitsklasse 2 (en: „Engineering method") und Genauigkeitsklasse 3 (en:„Survey method").
Diese Internationale Norm behandelt nicht die Analyseverfahren des von Flüssigkeitspumpen erzeugten Körper- und Flüssig¬keitsschalls.
ANMERKUNG 2 Diese Internationale Norm dient der Vervollständigung von EN 809.
Pompes et groupes motopompes pour liquides - Code d'essai acoustique - Classes de précision 2 et 3 (ISO 20361:2015)
L'ISO 20361:2015 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 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 de bruit, 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 de l'ISO 20361:2015 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 l'ISO 20361:2015 sont des méthodes d'expertise (classe 2) et des méthodes de contrôle (classe 3).
L'ISO 20361:2015 ne traite pas de la caractérisation du bruit solidien ni du bruit liquidien générés par les pompes pour liquides.
Črpalke za tekočine in črpalni agregati - Merjenje hrupa - Razreda točnosti 2 in 3 (ISO 20361:2015)
Ta mednarodni standard določa vse potrebne informacije za učinkovito določanje, objavljanje in preverjanje emisij hrupa črpalk za tekočine in črpalnih agregatov, ki bo potekalo pod standardiziranimi pogoji (glejte 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 navedenih mestih 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 mednarodnega standarda 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 mednarodni standard, so inženirske metode (razred 2) in metode raziskovanja (razred 3).
Ta mednarodni standard ne zajema karakterizacije strukturnega zvoka in vodnega hrupa, ki ju proizvajajo črpalke za tekočine.
OPOMBA Ta mednarodni standard je namenjen dopolnitvi standarda EN 809.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
