IEEE Standard Method for Measuring the Effectiveness of Electromagnetic Shielding Enclosures IEEE测量电磁屏蔽外壳有效性的标准方法
发布日期: 2007-02-28
本标准提供了在9 kHz至18 GHz(可扩展至50 Hz至100 GHz)频率下确定电磁(EM)屏蔽外壳有效性的统一测量程序。屏蔽外壳的所有者应提供测试屏蔽的频率,以及通过/失败的屏蔽效能(SE)限值。本标准建议了一系列测试频率,可为屏蔽的有效性提供非常高的置信度。本标准未定义通过或失败的SE限值。
This standard provides uniform measurement procedures for determining the effectiveness of electromagnetic (EM) shielding enclosures at frequencies from 9 kHz to 18 GHz (extendable down to 50 Hz and up to 100 GHz). The owner of the shielding enclosure shall provide the frequencies at which the shield will be tested, and the shielding effectiveness (SE) limits for pass/fail. This standard suggests a range of test frequencies that would provide very high confidence in the effectiveness of the shield. This standard dose not define SE limits for pass or fail.
