IEEE C37.98 – IEEE Standard for Seismic Qualification Testing of Protective Relays and Auxiliaries for Nuclear Facilities

Revision Standard – Active.The methods and conditions for seismic qualification of protective relays and auxiliariessuch as test and control switches, terminal blocks, and indicating lamps for use in nuclearfacilities are described in this standard. The primary intent of this standard is to focus on fragility testing and seismic qualification, also known as proof testing (either to generic levels or specific levels). This standard covers relays used in nuclear facilities, but may also be applied to any area in which the seismic response of relays is a design consideration. The prerequisites for the seismic test are defined in IEEE Std C37.105¿¿¿.
