Six Months' RuleReport on Voting5(CO)285(CO)3145-1 © IEC- 5 -INTERNATIONAL ELECTROTECHNICAL COMMISSIONSTEAM TURBINESPart 1: SpecificationsFOREWORD1)The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees onwhich all the National Committees having a special interest therein are represented, express, as nearly aspossible, 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 NationalCommittees in that sense.3)In order to promote international unification, the IEC expresses the wish that all National Committeesshould adopt the text of the IEC recommendation for their national rules in so far as national conditions willpermit. Any divergence between the IEC recommendation and the corresponding national rules should, asfar as possible, be clearly indicated in the latter.This part of International Standard IEC 45 has been prepared by IEC TechnicalCommittee No. 5: Steam turbines.The text of this part is based on the following documents:Full information on the voting for the approval of this part can be found in the VotingReport indicated in the above table.Annex A forms an integral part of this part of IEC 45.SIST IEC 60045-1:2000



45-1©IEC- 7 -INTRODUCTIONThe first edition of IEC 45 was issued in 1931. Subsequent revisions were made, the lastbeing in 1970. Since then, intensive development has resulted in the availability of morehighly-rated turbines.The development of turbines suitable for use with water-cooled nuclear reactors has pro-ceeded in parallel, resulting in the production of large turbines for use with steam which isinitially dry-saturated or slightly wet.The demands made upon turbine control systems have increased simultaneously with thedevelopment of new control technologies, such as electro-hydraulic systems. Increasedreliability, higher standards of dynamic performance, suitability for two-shift operation, andincreased attention to health and safety are among the aspects now requiring highstandards of achievement.It has therefore become necessary to specify a turbine in more detail than was formerlyneeded. In consequence, this part of IEC 45 has been completely re-written, and is accor-dingly more comprehensive than earlier editions.Wherever practicable, this part of IEC 45 takes into account the scope for applying tosmaller turbines developments originally intended for larger machines, without implyingthat such applications would always be necessary or advantageous.SIST IEC 60045-1:2000
