EN 61064:1993

Acceptance tests for steam turbine speed control systems

Contains recommendations for the conduct of tests of speed control systems of steam turbines. Applies primarily to constant speed steam turbines but may be applied where appropriate for other types of turbines. The purpose of the tests described in this publication is to verify the criteria guaranteed by the manufacturer and to check compliance with EN 60045-1.

Abnahmeprüfungen für Dampfturbinen-Regelsysteme

Essais de réception des systèmes de régulation de vitesse des turbines à vapeur

Contient des recommandations pour la conduite des essais des systèmes de régulation de vitesse des turbines à vapeur. S'applique essentiellement aux turbines à vapeur à vitesse constante mais peut être appliquée selon le cas à d'autres types de turbines. Le but des essais est de vérifier les critères garantis par le constructeur et la conformité avec la EN 60045-1.

ACCEPTANCE TESTS FOR STEAM TURBINE
SPEED CONTROL SYSTEMS
FOREWORD
1) The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
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)30 5(CO)33
Full information on the voting for the approval of this standard can be found in the Voting
Report indicated in the above table.
