IEC 61500:2018 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 61500:2018 establishes requirements for data communication which is used in systems performing category A functions in nuclear power plants. It covers also interface requirements for data communication of equipment performing category A functions with other systems including those performing category B and C functions and functions not important to safety. This document gives requirements for functions and properties of on-line plant data communication by reference to IEC 60880 and IEC 60987, produced within the framework of IEC 61513. It requires categorisation of the communication functions in accordance with IEC 61226. This new edition includes the following significant technical changes with respect to the previous edition:
- the changes introduced to previously referenced standards have been confirmed to apply;
- relevant newly published standards have been referenced;
- lessons learned from several industrial applications have been incorporated.Technology -
Technical committeeTypeAcronymIEC 61499-4CommitteePublished year2013Description
IEC 61499-4:2013 defines rules for the development of compliance profiles, which specify the features of IEC 61499-1 and 61499-2 to be implemented in order to promote the following attributes of IEC 61499-based systems, devices and software tools:
- interoperability of devices from multiple suppliers;
- portability of software between software tools of multiple suppliers;
- and configurability of devices from multiple vendors by software tools of multiple suppliers. This second edition cancels and replaces the first edition published in 2005. It constitutes a technical revision and includes the following significant technical changes: Table B.1 has been updated for consistency with Table 8 of IEC 61499-1:2013. -
Technical committeeTypeAcronymIEC 61499-2CommitteePublished year2012Description
IEC 61499-2:2012 defines requirements for software tools to support the following systems engineering tasks enumerated in IEC 61499-1:
- the specification of function block types;
- the functional specification of resource types and device types;
- the specification, analysis, and validation of distributed IPMCSs;
- the configuration, implementation, operation, and maintenance of distributed IPMCSs;
- the exchange of information among software tools. This second edition cancels and replaces the first edition published in 2005 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The contents of Annex A have been updated to conform to the technical changes of the second edition of IEC 61499-1. CDATA sections are now allowed for the textual contents of algorithms in Tables A.4 and A.5. -
Technical committeeTypeAcronymIEC 61499-1CommitteePublished year2012Description
IEC 61499-1:2012 defines a generic architecture and presents guidelines for the use of function blocks in distributed industrial-process measurement and control systems (IPMCSs). This architecture is presented in terms of implementable reference models, textual syntax and graphical representations. The models given in this standard are intended to be generic, domain independent and extensible to the definition and use of function blocks in other standards or for particular applications or application domains. It is intended that specifications written according to the rules given in this standard be concise, implementable, complete, unambiguous, and consistent. This second edition cancels and replaces the first edition published in 2005 an constitutes a technical revision. It includes the significant technical changes with respect to the previous edition related to: Execution control, Temporary variables, Service sequences, the syntax for mapping of FB instances, the Syntax for definition of segment types, the Function block types for interoperation with programmable controllers and the READ/WRITE management commands.

Technical committeeTypeAcronymIEC 61468CommitteePublished year2021Description
IEC 61468:2021 applies to in-core neutron detectors, viz. self-powered neutron detectors (SPNDs), which are intended for application in systems important for nuclear reactor safety: protection, instrumentation and control. This document contains SPND characteristics and test methods. In this document, the main sources of errors, and the possibilities for their minimization are also considered. This document contains requirements, recommendations and instructions concerning selection of SPND type and characteristics for various possible applications.
This document about SPNDs uses the basic requirements of IEC 61513 and IEC 60568 and complements them with more specific provisions in compliance with IAEA Safety Guides.
This second edition cancels and replaces the first edition, published in 2000, and its Amendment 1, published in 2003.
This edition includes the following significant technical changes with respect to the previous edition:
a. Title modified.
b. Justify the requirements for SPND characteristics in terms of influencing factors.
c. Align the terminology with the current state of the regulatory framework.Technology -

Technical committeeTypeAcronymIEC 61427-2:2015CommitteePublished year2015KeywordsDescription
IEC 61427-2:2015 relates to secondary batteries used in on-grid Electrical Energy Storage (EES) applications and provides the associated methods of test for the verification of their endurance, properties and electrical performance in such applications. The test methods are essentially battery chemistry neutral, i.e. applicable to all secondary battery types. On-grid applications are characterized by the fact that batteries are connected, via power conversion devices, to a regional or nation- or continent-wide electricity grid and act as instantaneous energy sources and sinks to stabilize the grids performance when randomly major amounts of electrical energy from renewable energy sources are fed into it. Related power conversion and interface equipment is not covered by this part of IEC 61427.
