摘　　要：电磁屏蔽室的屏蔽效能检测是衡量和判定屏蔽室等级的主要手段,因此正确选定其依据的屏蔽等级和测量方法的标准非常重要。文中对现行电磁屏蔽室屏蔽效能等级和测量方法的相关标准进行了梳理和对比,为在实际测量和确定屏蔽室等级时正确选定恰当的标准提出了可供参考的意见。另外结合工程实际,对屏蔽室单点与多点接地、绝缘、屏蔽门的设置等问题进行了讨论。Measuring the shielding effectiveness of electromagnetic shielded enclosures is the only way to determine the grade of electromagnetic shielded enclosures. Therefore it is important to select the appropriate criteria for measurement method and classification. In this paper,the current standards for classification and measurement method are compared. Some suggestions about how to select the appropriate criteria in the actual measurement are given. Finally,some issues on single point and multi-point grounding,insulation,and electromagnetic shielding door settings are discussed.
