Industrial-process control valves - Part 8-4: Noise considerations - Prediction of noise generated by hydrodynamic flow

Establishes a method to predict the noise generated in a control valve by liquid flow and the resulting noise level measured downstream of the valve and outside of the pipe.

Vannes de régulation des processus industriels - Partie 8-4: Considérations sur le bruit - Prévision du bruit généré par un écoulement hydrodynamique

Etablit une méthode pour prévoir le bruit engendré dans une vanne de régulation par un écoulement liquide et le niveau de bruit mesuré en aval de la vanne et à l'extérieur de la tuyauterie. Le bruit peut être généré à la fois par des turbulences normales et par la cavitation du liquide dans la vanne.

This European Standard was approved by CENELEC on 2005-11-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech

Foreword
The text of document 65B/556/FDIS, future edition 2 of IEC 60534-8-4, prepared by SC 65B, Devices,
of IEC TC 65, Industrial-process measurement and control, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 60534-8-4 on 2005-11-01.
This European Standard supersedes EN 60534-8-4:1994.
The noise prediction methods for hydrodynamic flow presented in this standard have been revised.
The improvements are mainly in the acoustic efficiency factors for cavitating flow for single orifice,
multi-stage and multi-hole trims and in the determination of transmission losses. This revised standard
permits the prediction of the noise pressure levels by calculation without the need for coefficients
determined by testing.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-08-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-11-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 60534-8-4:2005 was approved by CENELEC as a
European Standard without any modification.
