Annotation of standard text IEC 60534-8-2-ed.2.0 :
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. La CEI 60534-8-2:2011 decrit la methode de mesure du niveau de pression acoustique du a un debit de liquide au travers dune vanne de regulation, et la methode de determination de laugmentation caracteristique du bruit due au debut de la cavitation. Elle definit egalement lequipement, les methodes et procedures de mesure en laboratoire du bruit aerien, necessaires a la determination de ces caracteristiques. Deux methodes dessai pour les caracteristiques de generation de bruit des vannes de regulation sont fournies. La premiere est une methode uniforme de mesure du bruit rayonne par la vanne et la tuyauterie dessai associee, y compris les restrictions fixes au travers desquelles passe le fluide dessai (eau) (voir Note 1). La seconde consiste en une procedure 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 deuxieme edition annule et remplace la premiere edition parue en 1991, et constitue une revision technique qui inclut la mesure du bruit interne.
