Pumps - Rotodynamic pumps - Circulation pumps having a rated power input not exceeding 200 W for heating installations and domestic hot water installations - Part 2: Noise test code (vibro-acoustics) for measuring structure- and fluid-borne noise
This part of EN 1151 specifies a test code for the vibro-acoustic characterisation of circulation pumps as defined in EN 1151-1, and is limited to circulation pumps with threaded connections of 1½ inch. The test code comprises the test rig, the measurement method and the test conditions.
The characterisation principle is based on measuring the structure-borne and the fluid-borne power transmitted respectively by vibration and pressure fluctuations in the pipe connected to a circulation pump.
Pumpen - Kreiselpumpen - Umwälzpumpen mit elektrischer Leistungsaufnahme bis 200 W für Heizungsanlagen und Brauchwassererwärmungsanlagen für den Hausgebrauch - Teil 2: Geräuschprüfvorschrift (vibro-akustisch) zur Messung von Körperschall und Flüssigkeitsschall
Dieser Teil von EN 1151 legt eine Prüfvorschrift für die vibro-akustische Beschreibung von Umwälzpumpen nach EN 1151-1 fest, ist jedoch auf Umwälzpumpen mit einer Schraubverbindung von 1½" beschränkt. Die Prüfvorschrift umfasst den Prüfstand, das Messverfahren und die Prüfbedingungen.
Grundlage der Beschreibung ist die Messung von Körperschallleistung und Flüssigkeitsschallleistung, die durch Schwingungen bzw. Druckpulsationen in der mit der Umwälzpumpe verbundenen Rohrleitung weitergeleitet werden.
Pompes - Pompes rotodynamiques - Circulateurs de puissance absorbée n'excédant pas 200 W, destinés aux installations de chauffage central et d'eau chaude sanitaire domestique - Partie 2 : Code d'essai acoustique (vibro-acoustique) pour le mesurage des bruits solidiens et de liquide
La présente partie de l’EN 1151 spécifie un code d'essai pour la caractérisation vibro-acoustique des
circulateurs tels que définis dans l'EN 1151-1, et est limitée aux circulateurs ayant des raccords filetés de 1"½.
Le code d'essai comprend la boucle d’essai, la méthode de mesurage et les conditions d’essai.
Le principe de caractérisation est basé sur la mesure de la puissance, solidienne et dans le liquide, transmise
respectivement par vibration et par fluctuations de pression dans le tuyau raccordé au circulateur.

time averaged rate of flow of the acoustic energy per cross section of fluid transmitted lengthways the straight pipe by internal pressure fluctuations NOTE 1 Its sign can be positive or negative indicating the sense of energy propagation. NOTE 2 Fluid-borne intensity is expressed in W/m2. 3.2 fluid-borne power Pfb net acoustic power emitted by a source of pressure fluctuations in the connected straight pipe 〈circulation pumps〉
NOTE 1 Fluid-borne power is always positive. NOTE 2 Fluid-borne power is expressed in W. 3.3 structure-borne intensity Isb time averaged rate of flow of the vibrational energy per unit of length transmitted lengthways the straight pipe by vibration
NOTE 1 Its sign can be positive or negative indicating the sense of energy propagation. NOTE 2 Isb is an average of the structure borne intensity over the pipe wall thickness and is therefore expressed in W/m.
