What is BS EN 61587-3 - Electromagnetic shielding performance tests for cabinets and subracks about? 
Cabinets are useful in preventing electrical shock to equipment users and help in protecting the contents from the environment. BS EN 61587-3 is a part of an international multi-series standard that focuses on aspects of mechanical structures for electrical and electronic equipment. BS EN 61587-3 specifies the tests for empty cabinets and subracks concerning electromagnetic shielding performance, in the frequency range of 30 MHz to 3000 MHz.
BS EN 61587-3 provides stipulated attenuation values 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. BS EN 61587-3 support the measures to achieve electromagnetic compatibility but does not replace the final testing of compliance of the equipped enclosure.
