Technical committeeTypeAcronymIEC 62385CommitteePublished year2007Description
Defines the requirements for demonstrating acceptable performance of safety system instrument channels through response time testing, calibration verification, and other means. The same requirements may be adopted for demonstrating the acceptable performance of non-safety systems and other instrument channels.

Technical committeeTypeAcronymIEC 62342CommitteePublished year2007Description
Provides strategies, technical requirements, and recommendations for the management of ageing of nuclear power plant instrumentation and control systems and associated equipment. Also includes annexes on test methods, procedures, and technologies that may be used to verify proper operation of such equipment and aim to prevent ageing degradation from having any adverse impact on the plant safety, efficiency, or reliability. Applies to all types of nuclear power plants and relates primarily to safety.

Technical committeeTypeAcronymIEC 62340CommitteePublished year2007Description
Gives requirements related to the avoidance of CCF of I&C systems that perform category A functions; additionally requires the implementation of independent I&C systems to overcome CCF, while the likelihood of CCF is reduced by strictly applying the overall safety principles of IEC SC 45A (notably IEC 61226, IEC 61513, IEC 60880 and IEC 60709); gives an overview of the complete scope of requirements relevant to CCF.

Technical committeeTypeAcronymIEC 62138CommitteePublished year2018Description
IEC 62138:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 62138:2018 specifies requirements for the software of computer-based instrumentation and control (I&C) systems performing functions of safety category B or C as defined by IEC 61226. It complements IEC 60880 which provides requirements for the software of computer-based I&C systems performing functions of safety category A. It is consistent with, and complementary to, IEC 61513. Requirements that are not specific to software are deferred to IEC 61513. This new edition includes the following significant technical changes with respect to the previous edition:
- align the standard with standards published or revised since the first edition, in particular IEC 61513, IEC 60880, IEC 62645 and IEC 62671;
- merge two clauses in order to avoid repetitions of text;
- introduce requirements on traceability in consistency with IEC 61513;
- introduce new annexes.Technology -
Technical committeeTypeAcronymIEC 62003CommitteePublished year2020Description
IEC 62003:2020 establishes requirements for electromagnetic compatibility testing of instrumentation, control, and electrical equipment supplied for use in systems important to safety at nuclear power plants and other nuclear facilities. The document lists the applicable IEC standards (principally the IEC 61000 series) which define the general test methods, and provides the necessary application-specific parameters and criteria to ensure that nuclear safety requirements are met.
This second edition cancels and replaces the first edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition:
a) title modified.
b) expand the scope to encompass Electromagnetic Magnetic Compatibility (EMC) considerations for electrical equipment.
c) provide guidance for addressing the use of wireless technology.
d) enhance the description of the electromagnetic environment to provide clarification when selecting custom test levels or for test exemptions.
e) include example information to be contained within an EMC test plan.
f) provide guidance for characterization of the electromagnetic environment at the point of installation within a nuclear facility.Technology -
Technical committeeTypeAcronymIEC 61888CommitteePublished year2002Description
Defines the requirements for assuring that automatic setpoints for nuclear safety system instrumentation are established and maintained within specified limits in nuclear power plants and nuclear reactor facilities.
Technology -
Technical committeeTypeAcronymIEC 61839CommitteePublished year2000Description
Specifies functional analysis and assignment procedures for the design of the control-room system for nuclear power plants and gives rules for developing criteria for the assignment of functions. Supplements IEC 60964. Is applicable to the design of new control-rooms or to backfits to existing control-rooms.

Technical committeeTypeAcronymIEC 61772CommitteePublished year2009Description
IEC 61772:2009 supplements IEC 60964 and presents design requirements for the application of VDUs in main control rooms of nuclear power plants. Assists the designer in specifying VDU applications including displays on individual workstations and larger displays for group-working or distant viewing. The main technical changes with respect to the previous edition are as follows:
- expand the previous text to cover the use of large screen displays, to provide improved recommendations on the use of colour, and to improve the coverage of back-fit or upgrade applications;
- present examples of good practice.Technology
