Requirements and guidance for the seismic qualification of metal-enclosed power switchgear assemblies including switching, interrupting, control, instrumentation, metering, and protective and regulating devices mounted there in are provided in this guide. As used in this guide, the word switchgear shall mean metal-enclosed power switchgear assemblies with the requirements as defined in IEEE Std C37.20.1, Standard for Metal-Enclosed Low-Voltage Power Circuit Breaker Switchgear, IEEE Std C37.20.2, Standard for Metal-Clad Switchgear, and IEEE Std C37.20.3, Standard for Metal-Enclosed Interrupter Switchgear. By definition, metal-enclosed power switchgear assemblies include metal-clad switchgear, metal-enclosed interrupter switchgear, and low-voltage power circuit breaker switchgear. Metal-enclosed bus or control switchboards are not covered in this guide.

PC37.81
Guide for Seismic Qualification of Class 1E Metal-Enclosed Power Switchgear Assemblies
This guide provides requirements and guidance for the seismic qualification of metal-enclosed power switchgear assemblies including switching, interrupting, control, instrumentation, metering, protective, and regulating devices mounted there in. This guide helps equipment manufacturers to establish procedures that yield data to substantiate performance or by equipment users to evaluate and verify performance of representative devices and assemblies as part of an overall qualification effort. In this guide, the word switchgear means metal-enclosed power switchgear assemblies with the requirements as defined in IEEE Std C37.20.1, IEEE Std C37.20.2, IEEE Std C37.20.3. By definition, metal-enclosed power switchgear assemblies include metal-clad switchgear, metal-enclosed interrupter switchgear, and low-voltage power circuit breaker switchgear. This guide does not cover metal-enclosed bus or control switchboards.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
C37.81-1989
IEEE Guide for Seismic Qualification of Class 1E Metal-Enclosed Power Switchgear Assemblies
This standard provides specific requirements and guidance for seismic qualification of metal-enclosed power switchgear assemblies. This guide may also be used in other applications in which seismic response of metal-enclosed power switchgear assemblies is a consideration.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
