1.1 General
This part of IEC 60953
establishes a Supplementary Standard for thermal verification tests of retrofitted steam turbines.
The rules given in this document follow the guidance given in IEC 60953‑0, but contain amendments and supplements regarding guarantees and verification of
the guarantees by thermal acceptance tests on retrofitted steam turbines.
General principles for the preparation, performance, evaluation, comparison with guaranteed
values and the determination of the measurement uncertainties of verification tests are given in this document.
This document is applicable only when the retrofit involves some hardware change in
the steam turbine equipment. Conversely, any modification on the cycle or any retrofit
of other equipment of the power plant (e.g. boiler, feedwater heaters, etc.) is not
covered by this document.
