Annotation of standard text IEC 60953-4-ed.1.0 :
IEC 60953-4:2026 is intended to establish a Supplementary Standard for routine test of steam turbines. The rules given in this document follow the guidance given in IEC 60953-0, but contain amendments and supplements regarding the analysis and supervision of relative performance by routine testing of steam turbine. General principles for the preparation, performance evaluation, trends of performance parameters and the determination of the measurement uncertainty of periodic routine tests are given in this document. This document is applicable to routine testing covering a wide range of accuracy on steam turbines of every type, rating and application, operating with superheated or saturated steam. This document is not intended for application in acceptance tests of new units or retrofits and its application for such is strongly not recommended. The purpose of this document is to cover the existing steam turbine components which influence the efficiency of the power plant. This document helps the parties determine the most appropriate parameters that characterize the relative performance change and that could be used as long-term performance monitoring and analysis. IEC 60953-4:2026 etablit une norme supplementaire pour les essais individuels de serie des turbines a vapeur. Les regles etablies dans le present document suivent les recommandations de lIEC 60953-0, mais contiennent des amendements et des ajouts qui concernent lanalyse et le controle des performances relatives par des essais individuels de serie realises sur les turbines a vapeur. Le present document etablit les principes generaux pour la preparation, levaluation des performances, les tendances des parametres de performance et la determination de lincertitude de mesure lors des essais individuels de serie. Le present document sapplique aux essais individuels de serie qui couvrent une large plage dexactitude sur les turbines a vapeur de chaque type, debit et application, fonctionnant avec de la vapeur surchauffee ou saturee. Le present document nest pas destine a etre applique dans le cadre des essais de reception des nouvelles unites ou des renovations, et lapplication du present document dans un tel cadre est fortement deconseillee. Le present document a pour objet de traiter les composants existants des turbines a vapeur qui ont une incidence sur le rendement de la centrale thermique. Il aide les parties a determiner les parametres les plus appropries qui caracterisent la variation relative des performances et qui peuvent etre utilises pour la surveillance et lanalyse des performances a long terme.
