Provides guidance to assist in selecting a fuse-link to ensure coordination with contactors or motor-starters (contactors with overload relay).[
]The coordination between motor-starters and the fuses which protect them is covered in IEC standards by test requirements such as those in IEC 60947, in particular parts 1 and 4.[
]Overcurrent protection of other equipment, such as motors, conductors, etc., is not covered by this publication.[

IEC 63391:2024 applies to security screening systems that utilize active millimetre-wave (MMW) imaging to inspect persons who are not inside vehicles, containers, or enclosures. Specifically, this document applies to systems used to detect objects carried on the body of the individual being screened at a security checkpoint. This document applies to systems that screen people using radiation in the range between 3 GHz and 150 GHz (100 mm to 2 mm).
This document specifies the technical requirements, test methods, and signage of the active MMW systems for security screening of humans.
This document does not specify minimum or baseline requirements of image quality, automated threat recognition (ATR) performance, nor does it specify a minimum detection time

IEC 62341-6-7:2024 specifies the standard measuring conditions and measuring methods for determining the optical characteristics of an OLED display with under-screen camera; other under-screen features, such as under-screen fingerprint or under-screen time of flight (TOF) can also be applied. This document applies to OLED displays such as mobile phone, monitor and TV with under-screen features.
NOTE Under-screen feature will want the display to be partially transparent and partially non-transparent, and this can be achieved only by certain types of display technology, for example OLED. This document mainly focuses on OLED display with under-screen feature.

IEC/IEEE 62582-1:2024 is available as IEC/IEEE 62582-1:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC/IEEE 62582-1:2024 contains requirements for application of the other parts of IEC/IEEE 62582 related to specific methods for condition monitoring in electrical equipment important to safety of nuclear power plants. It also includes requirements which are common to all methods. The procedures defined in IEC/IEEE 62582 are intended for detailed condition monitoring.
IEC/IEEE 62582 specifies condition monitoring methods in sufficient detail to enhance the accuracy and repeatability, and provide standard formats for reporting the results. The methods specified are applicable to electrical equipment containing polymeric materials. Some methods are especially designed for the measurement of condition of a limited range of equipment whilst others can be applied to all types of equipment for which the polymeric parts are accessible.

IEC/IEEE 63332-387:2024 defines the criteria for the application and testing of diesel generator (DG) units used as safety class standby power supplies in nuclear facilities. In general, the standard applies to new nuclear facilities as well as for upgrading or back-fitting of existing facilities. Existing facilities can voluntarily adopt the requirements to enhance the performance capabilities and reliability of the installed DG units. The standard can be used in applications where highly reliable onsite alternating current (AC) power source is required to maintain plant safety following an event with potential loss of offsite power for an extended duration.
This document provides the principal design criteria, the design features, testing, and qualification requirements for the individual DG units that enable them to meet their functional requirements as a part of the standby power supply under the conditions produced by the design basis events catalogued in the plant safety analysis.

IEC 62899-301-3:2024 defines measurement terms and methods related to the shape errors of printing plate rollers. Measurement terms include radius, total run-out, and three kinds of shape errors of printing plate rollers that are axial deviation, radial deviation, and cross-sectional deviation. The remaining shape error excluding the three errors mentioned above is defined as a residual shape error.
This document applies to printing plate rollers with or without patterns while excluding the pattern area for the measurement.

IEC TR 63368:2024 provides guidance on off-site real-time simulation tests of control and protection (C&P) systems for HVDC power transmission systems. The off-site real-time simulation tests are carried out after the testing of C&P devices and prior to on-site system tests.
This document covers point-to-point, back-to-back, and multi-terminal HVDC systems of line commutated converters (LCC), voltage-sourced converters (VSC) and hybrid HVDC technologies.
In order to provide practical guidance for the functional performance tests of HVDC power transmission systems, this document covers the test environment, the contents and methods of functional performance tests, and the test report.
