IEC/IEEE 60780-323:2016描述了核设施中使用的对安全和接口（电气和机械）重要的电气设备的基本要求。所述原则、方法和程序旨在用于鉴定设备、维护和扩展鉴定，以及在设备被修改时根据需要更新鉴定。当满足本标准中的资格要求时，证明并记录设备在适用的使用条件下执行安全功能的能力，包括设计基准事件和某些设计扩展条件，并降低环境诱发的常见故障风险- 导致设备故障。与前一版IEC 60780:1998相比，新版包括以下主要变化，这些变化与IEC 60780:1998和IEEE 323:2003在初始认证方面给出的独特标准认证惯例相一致，考虑到需要重新评估和延长电气设备的合格寿命，以延长核设施的运行寿命。

IEC/IEEE 60780-323:2016 describes the basic requirements for qualifying electrical equipment important to safety and interfaces (electrical and mechanical) that are to be used in nuclear facilities. The principles, methods, and procedures described are intended to be used for qualifying equipment, maintaining and extending qualification, and updating qualification, as required, if the equipment is modified. The qualification requirements in this standard, when met, demonstrate and document the ability of equipment to perform safety function(s) under applicable service conditions, including design basis events and certain design extension conditions, and reduce the risk of environmentally induced common-cause equipment failure. This new edition includes the following main changes with respect to the previous edition IEC 60780:1998 harmonizes in a unique standard qualification practices formerly given by IEC 60780:1998 and IEEE 323:2003 on initial qualification, takes into account the need to reassess and extend the qualified life of electrical equipment regarding projects to extend the operating life of nuclear facilities.
