This standard provides basic requirements, direction, and methods for qualifying class IE connection assemblies for service in nuclear power generating stations. These include connectors, terminations, and environmental seals in combination with related cables or wires as assemblies. Qualification of cable with connectors to this standard does not replace qualification to IEEE Std 383^TM-2003. This standard does not apply to containment electric penetrations, fire stops, in-line splices, or components for service within the reactor vessel. The qualification requirements in this standard, when met, demonstrate and document the ability of the equipment to perform safety function(s) under applicable service conditions (including design basis events) reducing the risks of common cause-equipment failures. This standard does not provide environmental stress levels and performance requirements.

The basic requirements for qualifying Class 1E Connection Assemblies and interfacesthat are to be used in nuclear power generating stations are described in this standard. Theprinciples, methods, and procedures described are intended to be used for qualifying ConnectionAssemblies, maintaining and extending qualification, and updating qualification, as required, if theConnection Assembly is modified. The qualification requirements in this standard, when met,demonstrate and document the ability of the Connection Assembly to perform safety function(s)under applicable service conditions including design basis events, reducing the risk of commoncauseConnection Assembly failure.
