本技术报告涵盖了减轻影响设施的外部电磁影响的指南，旨在确保电气和电子设备或系统之间的电磁兼容性（EMC）。这些影响包括闪电、射频发射机、电力线和电信瞬态、高空电磁脉冲（HEMP）和其他高功率电磁瞬态。更具体地说，本技术报告涉及辐射干扰的屏蔽和屏蔽安排，以及传导干扰的缓解。这些安排包括为工业、商业和住宅安装适当的电磁屏障。 适用于敏感电气或电子装置或系统的安装人员、制造商和用户，以及辐射水平可能会降低整体电磁（EM）环境的设备。它主要适用于新设施，但在经济上可行的情况下，也可适用于现有设施的扩建或改造。

This Technical Report covers guidelines for the mitigation of external electromagnetic influences impinging upon a facility, aimed at ensuring electromagnetic compatibility (EMC) among electrical and electronic apparatus or systems. These influences include lightning, RF transmitters, power-line and telecom transients, high-altitude electromagnetic pulse (HEMP) and other high-power electromagnetic transients. More particularly, this technical report is concerned with the arrangement of shielding and screening against radiated disturbances, and with mitigation of conducted disturbances. These arrangements include appropriate electromagnetic barriers for industrial, commercial, and residential installations. Is intended for use by installers, manufacturers and users of sensitive electrical or electronic installations or systems, and of equipment with emission levels that could degrade the overall electromagnetic (EM) environment. It applies primarily to new installations but, where economically feasible, it may be applied to extensions or modifications to existing facilities.
