This document describes the basic requirements for qualifying Class IE equipment and interfaces that are to be used in nuclear power generating stations. The requirements presented include the principies@ procedures@ and methods of qualification. These qualification requirements@ when met@ will confirm the adequacy of the equipment design under normal@ abnormal@ design basis everit@ post design basis event@ and containment test conditions for the performance of Class IE functions. Purpose The purpose of this document is to provide guidance for demonstrating the qualification of Class equipment including components or equipment of any interface whose failure could adversely affect the perfomance of Class 1E systems and electnc equipment. Qualification required in IEEE Std 279-1971 (ANSI N42.7-1972)@ Criteria for Protection Systems for Nuclear Power Generating Stations and IEEE Std 308-1971@ Cnteria for Class IE Power Systems for Nuclear Power Generating Stations can be demonstrated by using the guidance provided in this document. The qualification methods described shall be used for qualifying equipment and for updating qualificatior@ following modifications. Other qualification guides for specific electric equipment or test methods (for example@ IEEE Std 344-1971@ Guide for Seismic Qualification of Class I Electric Equipment for Nuclear Power Generating Stations) will present specific requirements and should be used to supplement this document.
