屏蔽性能的分析是在经典的IEEE标准299的基础上进行的，这通常是一种局部和频域方法，可能不足以全面评估在瞬变电磁场存在下通过实际外壳实现的保护水平。从受害者的角度出发，提出了一种新的全局方法，直接在时域内评估近场或平面波存在下的平均和最小保证屏蔽性能。该方法适用于分析所有典型的瞬态电磁干扰现象，并推荐用于关键设备或系统的保护等级分析。对性能数据进行了初步的统计分析。
The analysis of the shielding performance is conducted on the basis of the classical IEEE Standard 299, which is typically a local and frequency-domain approach, may be not sufficient for the thorough appraisal of protection levels achievable through actual enclosures in the presence of transient electromagnetic fields. Stemming from a victim point of view, a new, global approach is proposed for the assessment of average and minimum guaranteed shielding performance directly in the time domain, in the presence of either near fields or plane waves. The method is suitable for the analysis of all the typical transient EMI phenomena and recommended for the analysis of protection levels of mission-critical devices or systems. An elementary statistical analysis of performance data is also presented.
