This part of IEC 61587 specifies seismic requirements for cabinets or racks as defined in the IEC 60917 and IEC 60297 series. It applies, in whole or in part, only to the mechanical structures of cabinets or racks for electronic equipment, according to the IEC 60297 and the IEC 60917 series, and does not apply to electronic equipment or systems within the mechanical structures.
The object of this standard is to help ensure physical integrity and environmental performance in mechanical cabinets or racks, taking into account the need for different levels of performance in different applications and geographical regions. It is intended to give the user a high level of confidence in the selection of an equipment practice to meet specific needs. A specific test specimen has been selected (see figure 1).
