GB/T 18663.2-2021
Mechanical structures for electronic equipment—Tests for metric and inch system—Part 2: Seismic tests for cabinets and racks (English Version)

Scope: This document describes the seismic testing of cabinets and racks conforming to the IEC60917 (all parts) and IEC60297 (all parts) series. It only applies to mechanical structures that comply in whole or in part with electronic equipment cabinets and racks in accordance with the above series of standards, and does not apply to electronic equipment or systems installed within these mechanical structures. This document does not apply to cabinets or racks with seismic isolation structures, nor to external or internal seismic isolation structures. This document is intended to provide test conditions and standards as a reference for evaluating the ability of a cabinet or rack mechanical structure to withstand specific seismic intensities. To this end, this document specifies specimen conditions such as cabinet and rack dimensions (i.e. height, width and depth), load distribution, structural test conditions and RRS (required response spectrum) for uniaxial or triaxial acceleration as seismic Test waveform conditions, uniaxial or triaxial testing are optional.
