IEEE 323-1983

This standard describes the basic requirements for qualifying Class 1E equipment with interfaces that are to be used in nuclear power generating stations. The requirements presented include the principles, procedures, and methods of qualification. These qualification requirements, when met, will confirm the adequacy of the equipment design under normal, abnormal, design basis event, post design basis event, and in-service test conditions for the performance of safety function(s).

The purpose of this standard is to identify requirements for the qualification of Class 1E equipment, including those interfaces whose failure could adversely affect the performance of Class 1E equipment and systems. The methods described shall be used for qualifying equipment, extending qualification, and updating qualification if the equipment is modified. Other issued IEEE standards which present qualification methods for specific equipment or components, or both, and those that deal with parts of the qualification program, may be used to supplement this standard, as applicable.

Revision Standard - Superseded. The basic requirements for qualifying Class 1E equipment with interfaces that are to be used in nuclear power generating stations are described. The principles, procedures, and methods of qualification are covered. These qualification requirements, when met, will confirm the adequacy of the equipment design under normal, abnormal, design-basis-event, post-design-basis-event, and in-service test conditions for the performance of safety functions. The methods are to be used for qualifying equipment, extending qualification, and updating qualification if the equipment is modified.
