本标准规定了核电站和其他核设施中使用的lE级连接组件的基本要求、方向和鉴定方法。这些包括连接器、终端和环境密封件，以及作为组件的相关电缆或电线。根据本标准对带有连接器的电缆进行的鉴定不能取代IEEE Std 383（TM）-2015的鉴定。本标准不适用于安全壳电气贯穿件、防火挡块等- 线路拼接、反应堆容器内使用的部件或光纤连接器（参考IEEE Std 1682（TM）-2011）。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（包括设计基准事件）下执行安全功能的能力，以降低常见原因设备故障的风险。本标准不提供环境压力水平和性能要求。注——如果适用，可以使用提供特定设备、特定环境或鉴定程序特定部分鉴定方法的其他IEEE标准来补充本标准。 IEC/IEEE 60780-323-2016的参考书目列出了与设备鉴定相关的其他标准。

This standard provides basic requirements, direction, and methods for qualifying Class lE connection assemblies for service in nuclear power generating stations and other nuclear facilities. These include connectors, terminations, and environmental seals in combination with related cables or wires as assemblies. Qualification of cable with connectors to this standard does not replace qualification to IEEE Std 383(TM)-2015. This standard does not apply to containment electric penetrations, fire stops, in-line splices, components for service within the reactor vessel, or fiber optic connectors (refer to IEEE Std 1682(TM)-2011). The qualification requirements in this standard, when met, demonstrate and document the ability of the equipment to perform safety function(s) under applicable service conditions (including design basis events) reducing the risks of common cause equipment failures. This standard does not provide environmental stress levels and performance requirements. NOTE--Othere IEEE standards that present qualification methods for specific equipment, specific environments, or specific parts of qualification program may be used to supplement this standard, as applicable. The bibliography of IEC/IEEE 60780-323-2016 lists other standards related to equipment qualification.
