标准范围

IEC 62397:2022描述了适用于对核电站安全重要的I&C系统应用的电阻温度探测器(RTD)的要求。RTD的要求包括设计、材料、制造、测试、校准、采购和检验。用于核电站安全应用的RTD可分为直接浸没式和热电偶套管安装式RTD。本标准描述了核电厂（NPP）中使用的电阻温度探测器（RTD）的设计、材料选择、采购、建造和测试的要求。这些RTD可用于核安全I&C系统和/或非安全相关仪表系统。第二版取消并取代了2007年出版的第一版；它还取消并取代了IEC 61224:1993的第一版。与上一版相比，该版本包括以下重大技术变化。

IEC 62397:2022 describes the requirements for resistance temperature detectors (RTDs) suitable for applications in I&C systems important to safety of nuclear power plants. The requirements of RTDs include design, materials, manufacturing, testing, calibration, procurement, and inspection. RTDs used for safety applications in Nuclear Power Plants can be categorized into direct-immersed and thermowell-mounted RTDs.
This standard describes the requirements for the design, material selection, procurement, construction, and testing of resistance temperature detectors (RTDs) used in nuclear power plants (NPPs). These RTDs may be used in both the nuclear safety I&C systems and/or in the non-safety-related instrumentation systems.
This second edition cancels and replaces the first edition, published in 2007; it also cancels and replaces the first edition of IEC 61224:1993. This edition includes the following significant technical changes with respect to the previous edition.
