IEC 62003:2020规定了用于核电站和其他核设施安全重要系统的仪表、控制和电气设备的电磁兼容性测试要求。该文件列出了适用的IEC标准（主要是IEC 61000系列），这些标准定义了一般测试方法，并提供了必要的特定于应用的参数和标准，以确保满足核安全要求。 第二版取消并取代了2009年出版的第一版。与上一版相比，此版本包括以下重大技术变更: a)标题已修改。 b)扩大范围以涵盖电气设备的电磁兼容性(EMC)考虑因素。c)为解决无线技术的使用提供指导。 d)增强电磁环境的描述，以便在选择自定义测试级别或测试豁免时提供澄清。 e)包括EMC测试计划中包含的示例信息。 f)为核设施内安装点的电磁环境表征提供指导。

IEC 62003:2020 establishes requirements for electromagnetic compatibility testing of instrumentation, control, and electrical equipment supplied for use in systems important to safety at nuclear power plants and other nuclear facilities. The document lists the applicable IEC standards (principally the IEC 61000 series) which define the general test methods, and provides the necessary application-specific parameters and criteria to ensure that nuclear safety requirements are met.
This second edition cancels and replaces the first edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition:
a) title modified.
b) expand the scope to encompass Electromagnetic Magnetic Compatibility (EMC) considerations for electrical equipment.
c) provide guidance for addressing the use of wireless technology.
d) enhance the description of the electromagnetic environment to provide clarification when selecting custom test levels or for test exemptions.
e) include example information to be contained within an EMC test plan.
f) provide guidance for characterization of the electromagnetic environment at the point of installation within a nuclear facility.
