IEC 61557-12:2018 is available as IEC 61557-12:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61557-12:2018 specifies requirements for power metering and monitoring devices (PMD) that measure and monitor the electrical quantities within electrical distribution systems, and optionally other external signals. These requirements also define the performance in single- and three-phase AC or DC systems having rated voltages up to 1 000 V AC or up to 1 500 V DC. These devices are fixed or portable. They are intended to be used indoors and/or outdoors. Power metering and monitoring devices (PMD), as defined in this document, give additional safety information, which aids the verification of the installation and enhances the performance of the distribution systems. The power metering and monitoring devices (PMD) for electrical parameters described in this document are used for general industrial and commercial applications. This document does not address functional safety and cyber security aspects. This document is not applicable for:
– electricity metering equipment that complies with IEC 62053-21, IEC 62053-22, IEC 62053-23 and IEC 62053-24. Nevertheless, uncertainties defined in this document for active and reactive energy measurement are derived from those defined in IEC 62053 (all parts);
– the measurement and monitoring of electrical parameters defined in IEC 61557-2 to IEC 61557-9 and IEC 61557-13 or in IEC 62020;
– power quality instrument (PQI) according IEC 62586 (all parts);
– devices covered by IEC 60051 (all parts) (direct acting analogue electrical measuring instrument). IEC 61557-12:2018 cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) PMD-A has been withdrawn due the fact these devices are now mainly covered by the IEC 62586 series of standards.
b) Three categories of PMD have been created with a list of minimum required functions for each category.
c) Added a new Annex A explaining the different applications linked to the relevant standards and devices, and another new Annex C about the power factor conventions.Technology -

Technical committeeTypeAcronymIEC 61547CommitteePublished year2020Description
IEC 61547:2020 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 61547:2020 which deals with electromagnetic immunity requirements, applies to lighting equipment which is within the scope of IEC technical committee 34, including apparatus such as lamps, luminaires, and modules. This third edition cancels and replaces the second edition, published in 2009. This edition constitutes a technical revision This edition includes the following significant technical changes with respect to the previous edition:
- extension of scope with end-user replaceable modules and the combination of end-user replaceable module and independent auxiliary;
- clarification of module testing in a host system;
- increased ESD and surge test levels for road and street lighting equipment;
- the introduction of ESD testing under normal operation and handling conditions;
- removal of line to ground surge test for self-ballasted lamps ≤ 25 W.Technology -
Technical committeeTypeAcronymIEC 61513CommitteePublished year2011KeywordsDescription
Instrumentation and control (I&C) systems important to safety may be implemented using conventional hard-wired equipment, computer-based (CB) equipment or by using a combination of both types of equipment (see Note 1). IEC 61513:2011 provides requirements and recommendations for the overall I&C architecture which may contain either or both technologies. The main technical changes with regard to the previous edition are as follows:
- alignment with the latest revisions of IAEA documents;
- alignment with new editions of IEC 60880, IEC 61226, IEC 62138, IEC 62340 and IEC 60987;
- alignment with significant advances of software engineering techniques;
- integration of requirements for staff training.Technology -
Technical committeeTypeAcronymIEC 61512-4CommitteePublished year2009Description
