IEC 62651:2013描述了适用于核电厂（NPP）应用的热电偶的要求。热电偶与电阻温度探测器等其他温度测量设备一起广泛应用于核电站。它们简单而坚固，并具有一些特定的特性（测量范围和最高温度），这使得它们特别适合某些测量。本标准中给出的热电偶要求包括设计、材料、制造、测试、校准、采购和检验。

IEC 62651:2013 describes the requirements for thermocouples suitable for nuclear power plant (NPP) applications. Thermocouples are widely used in NPPs with other temperature measurement devices such as resistance temperature detectors. They are simple and robust and have some specific characteristics (range of measurement and maximum temperature) which make them uniquely suitable for some measurements. The requirements given in this standard for thermocouples include design, materials, manufacturing, testing, calibration, procurement, and inspection.
