Inactive-Reserved Standard

IEEE 334-2006

IEEE Standard for Qualifying Continuous Duty Class 1E Motors for Nuclear Power Generating Stations

Reaffirmed March 2012. It is required that Class 1E motors, with their interfaces, meet or exceed the specified performance requirements throughout their service life. This is accomplished through a program that includes, but is not limited to, design, qualification, production quality control, shipping, storage, installation, operation, maintenance, periodic testing, and surveillance. This standard addresses the qualification portion of the program. It discusses the requirement for maintenance, repair, and surveillance of motors to maintain qualification of motors throughout their installed life but does not provide detailed guidance about how these programmatic items must be implemented and maintained. The qualification requirements of this standard, when met, demonstrate and document the ability of the motor and/or insulation system to perform its safety function(s) under specified service conditions.

P334

IEEE Draft Standard for Qualifying Alternating Current Class 1E Motors for Nuclear Power Generating Stations

It is required that Class 1E motors, with their interfaces, meet or exceed the specified performance requirements throughout their service life. This is accomplished through a program that includes, but is not limited to, design, qualification, production quality control, shipping, storage, installation, operation, maintenance, periodic testing, and surveillance. This standard addresses the qualification portion of the program. It discusses the requirement for maintenance, repair, and surveillance of motors to maintain qualification of motors throughout their service life but does not provide detailed guidance about how these programmatic items must be implemented and maintained. The qualification requirements of this standard, when met, demonstrate and document the ability of the motor and/or insulation system to perform its safety function(s) under specified service conditions.

334-1994

IEEE Standard for Qualifying Continuous Duty Class 1E Motors for Nuclear Power Generating Stations

Superseded by IEEE Std 334-2006 Methods and requirements for qualifying continuous duty Class 1E motors for use in nuclear power generating stations are provided.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.
