EN IEC 61000-5-7 - MEASUREMENT OF THE ELECTROMAGNETIC SHIELDING EFFECTIVENESS OF THE ENCLOSURES

The following test method according to the standard EN IEC 61000-5-7 is applied for degrees of protection provided by empty enclosures against electromagnetic disturbances for frequencies between 10 kHz and 40 GHz.
The shielding protection is measured for the purpose of demonstrating that the enclosure provides adequate shielding of electromagnetic energy to support acceptable performance of the complete assembled units when tested to applicable IEC standards.
The purpose of this standard is to provide a repeatable means for evaluating the electromagnetic shielding performance of empty mechanical enclosures, including cabinets and subracks, and to specify a marking code to allow a manufacturer to select an enclosure with a known capability for attenuating electromagnetic fields.
The requirements for immunity to various types of electromagnetic disturbances, including lightning and high-altitude electro-magnetic pulse (HEMP) will need to be considered by manufacturers when determining the need for application of this standard for specific equipment and applications, and for the specific enclosure shielding requirements which are necessary as a function of frequency.

EMCTEST Technologies is a leading test laboratory in Italy and Europe for electromagnetic shielding effectiveness testing. Thanks to advanced instrumentation and extensive experience in the field, we perform measurements from 10 kHz to 110 GHz on materials and devices intended for industrial, telecommunications, medical, military, automotive, railway, marine, aerospace, scientific, governmental, and civil applications.
