Acoustics - Measurement of airborne noise emitted by steam turbines and driven machinery

Describes a method for the measurement of noise emitted by steam turbines including driven machinery operating under steady state conditions. The results are expressed in sound power levels and in sound pressure levels. Applies to steam turbines of all sizes without limitation of output.

Akustik - Messung von luftübertragenen Geräuschen emittiert von Dampfturbinen und angetriebenen Maschinen

Acoustique - Mesure du bruit aérien émis par les turbines à vapeur et les machines entraînées

Décrit une méthode de mesure du bruit rayonné par les turbines à vapeur et les machines entraînées fonctionnant en régime permanent. Les résultats sont donnés en niveau de puissance acoustique et en niveaux de pression acoustique. S'applique aux turbines à vapeur de toute taille sans limitation de puissance.

FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
1)
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
2) They have the form of recommendations for international use and they are accepted by the National
Committees in that sense.
3) In order to promote international unification, the IEC expresses the wish that all National Committees
should adopt the text of the IEC recommendation for their national rules in so far as national conditions will
permit. Any divergence between the IEC recommendation and the corresponding national rules should, as
far as possible, be clearly indicated in the latter.
This International Standard has been prepared by IEC Technical Committee No. 5: Steam
turbines.
The text of this standard is based on the following documents:
Six Months' Rule Report on Voting
5(CO)29 5(CO)32
Full information on the voting for the approval of this standard can be found in the Voting
Report indicated in the above table.
Annex A forms an integral part of this International Standard

INTRODUCTION
This standard is based on ISO 3746 and has been drafted in accordance with ISO 3740.
The main purpose of this standard is to describe a method for the measurement of noise
radiated by steam-turbines including driven machinery operating under steady state
conditions. The results are expressed in sound power levels and in sound pressure levels.
NOTE - For special environmental conditions, it may be possible to use the engineering methods based
on ISO 3744 resulting in a higher grade of accuracy. In this case no reference to this standard will be
made.
