标准范围

IEC 60772:2018适用于核电站安全壳结构中的电气穿透组件（EPA）。它涵盖了EPA的设计、计算、鉴定、制造、组装、测试和安装中要满足的工程安全要求。EPA为一个或多个电路提供穿过安全壳的气密和耐压穿透。EPA要求分为机械（如安全壳完整性）和电气或光学安全方面。机械要求适用于所有EPA。与上一版相比，此新版本包括以下重大技术变更:a)使术语和定义适应当前可用的原子能机构和IEC术语表。b)纳入各种新的定义和要求。

IEC 60772:2018 applies to electrical penetration assemblies (EPAs) in containment structures of nuclear power plants. It covers the engineering safety requirements to be met in the design, calculation, qualification, fabrication, assembly, testing, and installation of EPAs. EPAs provide gas-tight and pressure-resistant penetrations through the containment for one or more electrical circuits. EPA requirements are divided into mechanical (e.g. containment integrity), and electrical or optical aspects regarding safety. The mechanical requirements are valid for all EPAs.
This new edition includes the following significant technical changes with respect to the previous edition:
a) Adaptation of terminology and definitions to current available IAEA and IEC glossaries.
b) Inclusion of various new definitions and requirements.
