IEC 61587-3 (2013-02)

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
