This part of IEC 61587 specifies seismic tests for cabinets and racks accommodated with
IEC 60917 and 60297 series. It applies, in whole or in part, only to the mechanical structures
of cabinets and racks for electronic equipment according to the above cited series of
standards, while it does not apply to the electronic equipment or systems deemed to be
installed within these mechanical structures. This standard does not apply either to a cabinet
or a rack having an anti-seismic isolation structure, either external or internal.
This standard aims to provide test conditions and criteria that constitute a reference to
evaluate the ability of the mechanical structure of the cabinets or racks to acceptably
withstand specified seismic intensities. For this purpose, this standard specifies test specimen
conditions, such as dimensions (i.e. height, width and depth) of the cabinet and the rack,
load distribution, structural test condition and the RRS (required response spectra) of singleaxis
or tri-axis acceleration as the seismic test wave condition. The single-axis or tri-axis
acceleration is selectable.
