电子设备用机械构件.IEC 60917和IEC 60297的试验.第3部分:机箱、机柜及分机柜的电磁屏蔽性能试验

[中文适用范围]： IEC 61587的本部分规定了在30 MHz至3 000 MHz频率范围内对空机柜和子架进行电磁屏蔽性能@的测试。选择规定的衰减值来定义 IEC 60297 和 IEC 60917 系列的机柜和子架的屏蔽性能级别。屏蔽性能级别是根据工业应用典型领域的要求来选择的。他们将支持实现电磁兼容性的措施，但不能取代所配备外壳的最终合规性测试。该标准的目的是确保机柜和子架@的物理完整性和环境性能，同时考虑到不同应用中对不同性能水平的需求。其目的是让用户对选择满足其特定需求的产品有一定的信心。本标准全部或部分仅适用于空机柜，例如符合 IEC 60297 和 IEC 60917 的机柜和子架，不适用于安装电子设备时的机柜。机箱可以按照子架相同的方式进行测试，机箱可以按照机柜相同的方式进行测试。该标准的制定与 IEC 61000-5-7 密切相关，但特别关注子架和机柜以及所选频率范围内性能水平的确定。 [外文原描述]： IEC 61587-3:2013 specifies the tests for empty cabinets and subracks concerning electromagnetic shielding performance, in the frequency range of 30 MHz to 3 000 MHz. Stipulated attenuation values are chosen for the definition of the shielding performance level of cabinets and subracks for the IEC 60297 and IEC 60917 series. The shielding performance levels are chosen with respect to the requirements of the typical fields of industrial application. They will support the measures to achieve electromagnetic compatibility but cannot replace the final testing of compliance of the equipped enclosure. This second edition cancels and replaces the first edition issued in 2006. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows. This edition corrects the errors of EM code descriptions and the frequency range for the shielding performance is extended up to 3 000 MHz. Keywords: Electromagnetic, Shielding, Cabinets, Subracks
