GB/T 18663.5-2022 is the English-translated version of 电子设备机械结构公制系列和英制系列的试验第5部分：机箱、插箱和插件的地震试验.

GB/T 18663.5-2022 is the Chinese standard "Mechanical structures for electronic equipment - Tests for metric and inch system - Part 5: Seismic tests for chassis, subracks and plug-in units".

Its scope clause reads: This document specifies the seismic test requirements for enclosures, sub-racks and their plug-ins as defined in the IEC 60297 and IEC 60917 series. according to IEC 60297 and IEC 60917 series, which only apply in whole or in part to the mechanical structure of enclosures, sub-boxes and their plug-ins for electronic equipment, not Suitable for electronic components, equipment or systems within mechanical structures.

NOTE. A subrack can be an integral part of a chassis (often referred to in the industry as a subrack or chassis). The purpose of this document is to ensure the physical integrity of enclosures, sub-racks and plug-ins as defined by IEC 60297 and IEC 60917 so that their Maintain certain use and maintenance functions during and after the earthquake.

It is designed to provide users with sufficient confidence. Due to the various sizes, weights and mechanical complexities of the IEC 60297 and IEC 60917 series of enclosures, sub-racks and inserts The quality category specifies a minimum seismic test requirement.

Therefore, overall quality categories are specified in this document. However, inside the chassis and slot Mass distribution is considered "specific application" and is defined here as "intended use". Uniaxial acceleration or triaxial acceleration for seismic testing is optional.

1 Scope

This document specifies the seismic test requirements for enclosures, sub-racks and their plug-ins as defined in the IEC 60297 and IEC 60917 series. according to

IEC 60297 and IEC 60917 series, which only apply in whole or in part to the mechanical structure of enclosures, sub-boxes and their plug-ins for electronic equipment, not

Suitable for electronic components, equipment or systems within mechanical structures.

NOTE. A subrack can be an integral part of a chassis (often referred to in the industry as a subrack or chassis).

The purpose of this document is to ensure the physical integrity of enclosures, sub-racks and plug-ins as defined by IEC 60297 and IEC 60917 so that their

Maintain certain use and maintenance functions during and after the earthquake. It is designed to provide users with sufficient confidence.

Due to the various sizes, weights and mechanical complexities of the IEC 60297 and IEC 60917 series of enclosures, sub-racks and inserts

The quality category specifies a minimum seismic test requirement. Therefore, overall quality categories are specified in this document. However, inside the chassis and slot

Mass distribution is considered "specific application" and is defined here as "intended use".

Uniaxial acceleration or triaxial acceleration for seismic testing is optional.
