IEC TS 62257-350:2025 specifies the criteria for selecting and sizing inverters suitable for different off-grid applications integrating solar as an energy source. As well as off-grid systems, this document can also apply to inverters where a utility grid connection is available as a backup for charging batteries, but it is not intended to cover applications in which inverters synchronize and inject energy back into a utility grid, even though this capability can incidentally be a part of the functionality of the inverters. Single and multi-phase applications are included.

IEC TS 62607-6-26:2025, which is a Technical Specification, establishes a standardized method to determine the mechanical key control characteristics (KCCs)

• fracture stress
of 2D materials and nanoscale films using the

IEC 60749-23:2025 specifies the test used to determine the effects of bias conditions and temperature on solid state devices over time. It simulates the device operating condition in an accelerated way and is primarily for device qualification and reliability monitoring. A form of high temperature bias life using a short duration, popularly known as "burn-in", can be used to screen for infant-mortality related failures. The detailed use and application of burn-in is outside the scope of this document.
This edition includes the following significant technical changes with respect to the previous edition:
a) absolute stress test definitions and resultant test durations have been updated.

IEC 60749-21:2025 establishes a standard procedure for determining the solderability of device package terminations that are intended to be joined to another surface using tin-lead (SnPb) or lead-free (Pb-free) solder for the attachment. This test method provides a procedure for “dip and look” solderability testing of through hole, axial and surface mount devices (SMDs) as well as an optional procedure for a board mounting solderability test for SMDs for the purpose of allowing simulation of the soldering process to be used in the device application. The test method also provides optional conditions for ageing. This test is considered destructive unless otherwise detailed in the relevant specification.
NOTE 1 This test method does not assess the effect of thermal stresses which can occur during the soldering process. More details can be found in IEC 60749‑15 or IEC 60749‑20.
NOTE 2 If a qualitative test method is preferred, the Wetting balance test method can be found in IEC 60068-2-69.
This edition includes the following significant technical changes with respect to the previous edition:

IEC 62933-5-2:2025 primarily describes safety aspects for people and, where appropriate, safety matters related to the surroundings and living beings for grid-connected energy storage systems where an electrochemical storage subsystem is used. This document is applicable to the entire life cycle of BESS (from design to end of service life management). This document provides further safety provisions that arise due to the use of an electrochemical storage subsystem (e.g. battery system) in EES systems that are beyond the general safety considerations described in IEC 62933-5-1. This document specifies the safety requirements of an "electrochemical" energy storage system as a "system" to reduce the risk of harm or damage caused by the hazards of an electrochemical energy storage system due to interactions between the subsystems as presently understood.
