This standard specifies the test for empty cabinets and subracks concerning electromagnetic shielding performance in the frequency range of 30 MHz to 3 000 MHz. 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. The purpose of this test is to ensure physical integrity and environmental performance of cabinets and subracks, taking into account the need for different levels of performance in different applications. It is intended to give the user a level of confidence in the selection of products to meet his specific needs. This standard in whole or in part applies only to the empty enclosures and does not apply to the enclosures when electronic equipment is installed. Significant modifications with regard to the previous edition of this standard are that the frequency range for the shielding performance is extended up to 3 000 MHz, the transmitting antenna is described and the errors of EM code are corrected. The responsible committee is DKE/K 662 "Bauweisen" ("Mechanical structures") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
