Revision Standard - Superseded. Superseded by IEEE Std 334-2006 Methods and requirements for qualifying continuous duty Class 1E motors for use in nuclear power generating stations are provided. The methods are used for qualifying motors, extending the qualification, and updating the qualification if the motor's design or specified service conditions are modified. The requirements include the principles, procedures, and methods of qualification as they relate to continuous duty Class 1E polyphase squirrel cage ac motors.
This document describes the methods and requirements for qualifying continuous duty Class 1E motors for use in nuclear power generating stations. The requirements presented include the principles, procedures, and methods of qualification as they relate to continuous duty Class 1E polyphase squirrel cage ac motors. Other types of ac motors and dc motors may use techniques from this document, as applicable, in combination with basic qualification techniques from IEEE Std 323-1983. Compliance with this document meets the requirements of IEEE Std 323-1983 as applied to Class 1E continuous duty motors. The methods described shall be used for qualifying motors, extending the qualification, and updating the qualification if the motorâ€s design of specified service conditions is modified. Other IEEE and industry documents presenting qualification methods for specific components within the motor and dealing with parts of the qualification program may be used, as applicable, to supplement this document. References are made within this document to applicable standards that provide guidance.
The purpose of this document is to provide specific direction for the implementation of the requirements of IEEE Std 323-1983 as they apply to the specific features of continuous duty Class 1E motor qualification.
