IEC 60953-3:20 22本部分建立了改装汽轮机热验证试验的补充标准。 本文件中给出的规则遵循IEC 60953-0中给出的指南，但包含关于保证和通过改装汽轮机热验收试验验证保证的修正和补充。 本文件给出了验证试验的准备、性能、评估、与保证值的比较以及确定测量不确定度的一般原则。 本文件仅适用于改造涉及汽轮机设备的某些硬件变更时。相反，对循环的任何修改或发电厂其他设备（如锅炉、给水加热器等）的任何改造。）不在本文件的范围内。

IEC 60953-3:2022 This part 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.
