IEC 62765-2:20 19确定了纠正和防止温度传感器（如NPP电阻温度探测器（RTD）和热电偶（TC））老化对核电厂（NPP）安全的任何潜在影响的最低要求和适用实践。 本文件提供了对核电厂（NPP）安全重要的温度传感器老化管理的策略、技术要求和推荐实践，以确保可以识别老化，并在必要时采取适当的补救措施，以证明核电站的安全性不会受到损害。本文件与IEC 62342保持一致，IEC 62342为对核电厂安全至关重要的仪表和控制(I&C)系统的老化管理提供了指导

IEC 62765-2:2019 identifies minimum requirements and applicable practices for correcting and preventing any potential impacts on nuclear power plant (NPP) safety due to the ageing of temperature sensors, such as NPP resistance temperature detectors (RTDs) and thermocouples (TCs).
This document provides strategies, technical requirements, and recommended practices for the management of the ageing of temperature sensors important to safety in nuclear power plants (NPPs) to ensure that ageing can be identified and that suitable remedial actions are undertaken as necessary to demonstrate that the safety of the plant will not be impaired. This document is aligned with IEC 62342, which provides guidance on ageing management for instrumentation and control (I&C) systems important to safety in NPPs
