8-3:Considrations sur le bruit Mthode de prdiction du bruit arodynamique des vannes de rgulationAVANT-PROPOS1)La CEI(Commission lectrotechnique Internationale)est une organisation mondiale de normalisationcompose de lensemble des comits lectrotechniques nationaux(Comits nationaux de la CEI).La CEI apour objet de favoriser la coopration internationale pour toutes les questions de normalisation dans lesdomaines de llectricit et de llectronique.A cet effet,la CEI,entre autres activits,publie des Normesinternationales.Leur laboration est confie des comits dtudes,aux travaux desquels tout Comit nationalintress par le sujet trait peut participer.Les organisations internationales,gouvernementales et nongouvernementales,en liaison avec la CEI,participent galement aux travaux.La CEI collabore troitementavec lOrganisation Internationale de Normalisation(ISO),selon des conditions fixes par accord entre lesdeux organisations.2)Les dcisions ou accords officiels de la CEI concernant les questions techniques reprsentent,dans la mesuredu possible,un accord international sur les sujets tudis,tant donn que les Comits nationaux intressssont reprsents dans chaque comit dtudes.3)Les documents produits se prsentent sous la forme de recommandations internationales.Ils sont publiscomme normes,spcifications techniques,rapports techniques ou guides et agrs comme tels par lesComits nationaux.4)Dans le but dencourager lunification internationale,les Comits nationaux de la CEI sengagent appliquer defaon transparente,dans toute la mesure possible,les Normes internationales de la CEI dans leurs normesnationales et rgionales.Toute divergence entre la norme de la CEI et la norme nationale ou rgionalecorrespondante doit tre indique en termes clairs dans cette dernire.5)La CEI na fix aucune procdure concernant le marquage comme indication dapprobation et sa responsabilitnest pas engage quand un matriel est dclar conforme lune de ses normes.6)Lattention est attire sur le fait que certains des lments de la prsente Norme internationale peuvent fairelobjet de droits de proprit intellectuelle ou de droits analogues.La CEI ne saurait tre tenue pourresponsable de ne pas avoir identifi de tels droits de proprit et de ne pas avoir signal leur existence.La Norme internationale CEI 60534-8-3 a t tablie par le sous-comit 65B:Dispositifs,ducomit dtudes 65 de la CEI:Mesure et commande dans les processus industriels.Cette deuxime dition de la CEI 60534-8-3 annule et remplace la premire dition parueen 1995.Cette deuxime dition constitue une rvision technique.Le texte de cette norme est issu des documents suivants:FDISRapport de vote65B/400/FDIS65B/407/RVDLe rapport de vote indiqu dans le tableau ci-dessus donne toute

Part 8-3:Noise considerations Control valve aerodynamic noise prediction methodFOREWORD1)The IEC(International Electrotechnical Commission)is a worldwide organization for standardization comprisingall national electrotechnical committees(IEC National Committees).The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields.Tothis end and in addition to other activities,the IEC publishes International Standards.Their preparation isentrusted to technical committees;any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work.International,governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation.The IEC collaborates closely with the International Organizationfor Standardization(ISO)in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express,as nearly as possible,aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards,technical specifications,technical reports or guides and they are accepted by the NationalCommittees in that sense.4)In order to promote international unification,IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards.Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights.The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60534-8-3 has been prepared by subcommittee 65B:Devices,ofIEC technical committee 65:Industrial-process measurement and control.This second edition of IEC 60534-8-3 cancels and replaces the first edition published in 1995.This second edition constitutes a technical revision.The text of this standard is based on the following documents:FDISReport on voting65B/400/FDIS65B/407/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in
