This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. The basic principles, requirements, and methods for qualifying Class 1E protective relays and auxiliaries, such as test and control switches, terminal blocks, and indicating lamps, for applications in nuclear power generating stations are described. The qualification procedure is generic in nature and can be used to demonstrate the design adequacy of such equipment under normal, abnormal, design-basis-event, and post-design-basis-event conditions. Protective relays and auxiliaries located inside primary containment areas in a nuclear power generating station are not covered.

PC37.105
Standard for Qualifying Class 1E Protective Relays and Auxiliaries for Nuclear Power Generating Stations and Other Nuclear Facilities
This standard covers qualification of Class 1E protective relays and auxiliaries to be used outside the primary containment in Nuclear Power Generating Stations and Other Nuclear Facilities . Protective relays and auxiliaries located inside the primary containment in a Nuclear Power Generating Stations and Other Nuclear Facilities present special conditions beyond the scope of this document.
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.
No Superseded Standards
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No Inactive-Withdrawn Standards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.
C37.105-2010
IEEE Standard for Qualifying Class 1E Protective Relays and Auxiliaries for Nuclear Power Generating Stations
Basic principles, requirements, and methods for qualifying Class 1E protective relays and auxiliaries in nuclear power generating stations including digital and analog devices, but excluding devices located inside the primary containment, are covered.
