CEI EN 61587-3

Scope and object

This part of IEC 61587 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.

The purpose of this standard 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,
for example cabinets and subracks according to IEC 60297 and IEC
60917 and does not apply to the enclosures when electronic
equipment is installed. Chassis may be tested in the same way as
subracks and cases may be tested in the same way as cabinets.

This standard was developed in close relationship to IEC
61000-5-7 but with the specific focus on subracks and cabinets and
the determination of performance levels at the chosen frequency
range.
