IEC 61333:2019(Main)
Marking on ferrite cores

IEC 61333:2019 specifies marking locations and a coding system of marking on ferrite cores. An alphanumerical marking printed or attached to cores reduces the risk of incorrect assembly, mixing of materials and/or mixing of gapped cores on an assembly line. The markings of the inductance factor AL value or of the gap length are especially important to avoid this kind of problem, and their coding system is specified in this document.
This edition includes the following significant technical changes with respect to the previous edition：
a) the title of the document was changed;
b) the scope of this document was expanded;
c) the marking position instructions for ring cores, planar cores, RM-cores, PQ-cores and pot-cores were added in Clause 4 with a few additional descriptions;
d) the four-digit-maximum limit of material identification code has been deleted in 5.2;
e) in Table 1, the unit of AL has been changed from "nH" to "nH/N2".

IEC 60772:2018(Main)
Nuclear power plants - Instrumentation systems important to safety - Electrical penetration assemblies in containment structures

IEC 60772:2018 applies to electrical penetration assemblies (EPAs) in containment structures of nuclear power plants. It covers the engineering safety requirements to be met in the design, calculation, qualification, fabrication, assembly, testing, and installation of EPAs. EPAs provide gas-tight and pressure-resistant penetrations through the containment for one or more electrical circuits. EPA requirements are divided into mechanical (e.g. containment integrity), and electrical or optical aspects regarding safety. The mechanical requirements are valid for all EPAs.
This new edition includes the following significant technical changes with respect to the previous edition:
a) Adaptation of terminology and definitions to current available IAEA and IEC glossaries.
b) Inclusion of various new definitions and requirements.

Electric vehicle conductive charging system - Part 24: Digital communication between a DC EV supply equipment and an electric vehicle for control of DC charging

IEC 61851-24:2023, together with IEC 61851-23, applies to digital communication between a DC EV supply equipment and an electric road vehicle (EV) for control of conductive DC power transfer, with a rated supply voltage up to 1 000 V AC or up to 1 500 V DC and a rated output voltage up to 1 500 V DC.
This document also applies to digital communication between the DC EV charging/discharging station and the EV for system A, as specified in Annex A.
The EV charging mode is mode 4, according to IEC 61851-23.
Annex A, Annex B, and Annex C give descriptions of digital communications for control of DC charging specific to DC EV charging systems A, B and C as defined in IEC 61851-23.
This second edition cancels and replaces the first edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- Annex A and Annex B have been updated in line with IEC 61851-23:2023 and relevant standards.
