本国际标准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。本标准不提供环境压力水平或性能要求。与质量保证、电子设备的选择和使用、数字系统的设计和修改有关的其他方面不属于本标准的一部分。如适用，可使用其他IEC或IEEE标准来补充本标准，这些标准为特定设备、特定环境或认证计划的特定部分提供认证计划。 参考书目列出了与设备鉴定相关的其他标准。

This International Standard 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 standard does not provide environmental stress levels or performance requirements. Other aspects, relating to quality assurance, selection and use of electronic devices, design and modification of digital systems are not part of this standard. Other IEC or IEEE standards that present qualification programmes for specific equipment, specific environments, or specific parts of the qualification programme may be used to supplement this standard, as applicable. The bibliography lists other standards related to equipment qualification.
