Industrial-process control valves - Part 8-2: Noise considerations - Laboratory measurement of noise generated by hydrodynamic flow through control valves
IEC 60534-8-2:2011 includes the method for measuring the sound pressure level due to liquid flow through a control valve and the method for determining the characteristic increase of noise due to the onset of cavitation. It also defines the equipment, methods and procedures for the laboratory measurement of the airborne sound needed to determine these characteristics. Two methods are provided for testing the noise generating characteristics of control valves. The first is a uniform method of measuring the radiated noise from the valve and the associated test piping including fixed flow restrictions through which the test fluid (water) is passing. The second is a procedure for measuring the sound pressure levels within pipe systems upstream and downstream of the valve under fixed operating conditions. This second edition cancels and replaces the first edition published in 1991 and constitutes a technical revision that includes internal noise measurement.

Vannes de régulation des processus industriels - Partie 8-2: Considérations sur le bruit - Mesure en laboratoire du bruit créé par un écoulement hydrodynamique dans une vanne de régulation
La CEI 60534-8-2:2011 décrit la méthode de mesure du niveau de pression acoustique dû à un débit de liquide au travers d'une vanne de régulation, et la méthode de détermination de l'augmentation caractéristique du bruit due au début de la cavitation. Elle définit également l'équipement, les méthodes et procédures de mesure en laboratoire du bruit aérien, nécessaires à la détermination de ces caractéristiques. Deux méthodes d'essai pour les caractéristiques de génération de bruit des vannes de régulation sont fournies. La première est une méthode uniforme de mesure du bruit rayonné par la vanne et la tuyauterie d'essai associée, y compris les restrictions fixes au travers desquelles passe le fluide d'essai (eau) (voir Note 1). La seconde consiste en une procédure de mesure des niveaux de pression acoustique dans les tuyauteries en amont et en aval de la vanne, dans des conditions de fonctionnement fixes. Cette deuxième édition annule et remplace la première édition parue en 1991, et constitue une révision technique qui inclut la mesure du bruit interne.
Ventili za upravljanje v industrijskih procesih - 8-2. del: Hrup - Laboratorijske meritve hrupa zaradi hidrodinamičnega pretoka skozi ventile za upravljanje (IEC 60534-8-2:2011)
Ta del standarda IEC 60534-8 vključuje metodo za merjenje ravni zvočnega tlaka zaradi pretoka tekočin skozi ventil za upravljanje in metodo za določanje značilnega povečanja hrupa zaradi nastanka kavitacije. Določa tudi opremo, metode in postopke za laboratorijske meritve zvoka v zraku, potrebne za določitev teh
lastnosti. Navedeni sta dve metodi za preskušanje lastnosti ventilov za upravljanje, ki povzročajo hrup. Prva je enotna metoda za merjenje hrupa, ki prihaja iz ventila in
z njim povezanega preskusnega cevovoda vključno z ovirami stalnega toka, po katerih teče preskusna tekočina (voda) (glejte opombo 1). Merila za hrup so izražena z določitvijo ravni zvočnega tlaka obravnavanega ventila. Druga metoda je postopek za merjenje ravni zvočnega tlaka v cevnih sistemih višje in nižje od ventila v stalnih obratovalnih pogojih. Ker so nepravilnosti zaradi prenosa po cevi izločene, ima ta metoda prednost pri presoji akustičnih lastnosti ventilov.
Lastnosti hrupa, ki se določajo, so uporabne za:
a) opredelitev akustičnih lastnosti ventilov in sestavov ventilov ter značilnega faktorja razmerja tlaka xFz ventila za upravljanje;
b) napoved hrupa ventila v določenih procesnih pogojih;
c) primerjavo delovanja različnih ventilov in merilnih rezultatov;
d) načrtovanje ukrepov za podaljšanje življenjske dobe in zmanjšanje hrupa;
e) ugotavljanje možnih škodljivih vplivov na meritve z ultrazvočnim merilnikom pretoka;
f) opredelitev pravilne velikosti absorberjev zvoka.
OPOMBA 1: Preskusne tekočine razen vode ali ventili, ki nimajo cevovoda nižje v toku, ne spadajo v področje uporabe tega oddelka standarda IEC 60534-8.
OPOMBA 2: Faktor xFz se uporablja pri metodi za napoved hrupa iz standarda IEC 60534-8-4.
