IEEE 572 ERTA-2011 pdf download Errata to IEEE Standard for Qualification of Class 1E Connection Assemblies for Nuclear Power Generating Stations
1. Overview
1.1 Scope
This standard provides basic requirements, direction, and methods for qualifying Class lE connectionassemblies for service in nuclear power generating stations and other nuclear facilities. These includeconnectors, terminations,and environmental seals in combination with related cables or wires as assembliesQualification ofcable with connectors to this standard does not replace qualification to IEEE Std 383TM-2015.This standard does not apply to containment electric penetrations, fre stops, in-line splices, componentsfor service within the reactor vessel, or fiber optic connectors (refer to IEEE Std 1682TM-2011 (B9)’ Thequalification requirements in this standard, when met,demonstrate and document the ability of the equipmentto perform safety function(s) under applicable service conditions (including design basis events) reducing therisks of common cause equipment failures. This standard does not provide environmental stress levels andperformance requirements.
NOTE-Other IEEE standards that present qualification methods for specific equipment, specific environments,or specific parts of qualification program may be used to supplement this standard, as applicable. The bibliography ofIEC/IEEE 60780-323-2016 lists other standards related to equipment qualification.”
1.2 Purpose
The purpose of this standard is to provide specific direction for the implementation ofIEC/IEEE 60780-323-2016 for qualification as it pertains to qualification of connectors, terminations, andenvironmental seals (related to cables as assemblies).

3.Definitions
For the purposes ofthis document, the following terms and definitions apply. The IEEE Standards DictionaryOn/ine should be consulted for terms not defined in this clause.
baseline parameter: Initial technical data benchmarking acceptable performance of the evaluatedqualification test sample.
cable assembly: Cable or wires attached and interfaced to a connector, conduit seal, or sealing gland as anassembly. Cable assemblies are a type of connection assembly.
condition-based qualification: Oualification based on measurement of one or more condition indicators ofequipment,its components, or materials for which acceptance criteria can be correlated to the equipment’sability to function as specified during an applicable design basis event.
connection assembly: Connectors, terminations, and environmental seals which may or may not be incombination with related cables or wires as assemblies
connection assembly interface: The mechanism by which a connection assembly mates with its hostequipment. The connection assembly interface shall be considered in the qualifcation specification/testingand includes attributes such as mounting, sealing, use of conduit, and unsupported cable/conduit length.
design life: The time period during which satisfactory performance can be expected for a specific set of serviceconditions.
environmental seal: A device or system that restricts the passage of a gas or liquid through a boundary inconjunction with related cables or wires as an assembly.
generic connection assembly: A connection assembly that represents a family of connection assemblieshaving materials with the same properties, manufacturing processes, assembly techniques, limiting stressesdesign,and operating principles.
generic qualification: Qualification to a set of requirements designed to envelop the service conditions plusmargin ofa number ofspecific applications.
