IEC 60216-1:2025 specifies the general ageing conditions and procedures to be used for deriving thermal endurance characteristics and gives guidance in using the detailed instructions and guidelines in the other parts of IEC 60216. Although originally developed for use with electrical insulating materials and simple combinations of such materials, the procedures are considered to be of more general applicability and are widely used in the assessment of materials not intended for use as electrical insulation. In the application of this document, it is assumed that a practically linear relationship exists between the logarithm of the time required to cause the predetermined property change and the reciprocal of the corresponding absolute temperature (Arrhenius relationship). For the valid application of this document, no transition, in particular no first-order transition, is expected to occur in the temperature range under study. This edition includes the following significant technical changes with respect to the previous edition: a) the definition for temperature index (TI) has been updated; b) requirements for selection of related materials used, e.g. in different colours (5.1.2), have been added; c) test procedure for thickness sensitivity (5.5 et 6.6) has been added; d) Annex C "Concepts in earlier editions" has been deleted.

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: - revision to certain operating conditions in line with current working practices.

IEC 80601-2-89:2025 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL BEDS, hereafter referred to as MEDICAL BEDS as defined in 201.3.219, intended for CHILDREN as defined in 201.3.207, and ADULTS with atypical anatomy (ADULTS ranging outside the definition for ADULTS in 201.3.201). This document applies to both electrical and non-electrical(manual) MEDICAL BEDS with or without adjustable functions. This document applies to MEDICAL BEDS with an INTERNAL LENGTH of up to 180 cm suitable to a body length of 155 cm. If a MANUFACTURER wishes to make a bed that can be used by both a CHILD and an ADULT, e.g. INTERNAL LENGTH of 180 cm or more, then IEC 80601-2-52 and this document apply. This document does not apply to: • ADULT only beds covered by IEC 80601-2-52; • SPECIALITY MATTRESS covered by the ISO 20342 series; • incubators covered by IEC 60601-2-19; • devices for which the INTENDED USE is mainly for examination or transportation under medical supervision (e.g. stretcher, examination table). If a clause or subclause is specifically intended to be applicable to a MEDICAL BED only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to MEDICAL BEDS and to ME SYSTEMS, as relevant. HAZARDS inherent in the intended physiological function of MEDICAL BEDS or ME SYSTEMS within the scope of this document are not covered by specific requirements in this document except in IEC 60601-1:2005, IEC 60601-1:2005/AMD1:2012 and IEC 60601-1:2005/AMD2:2020, 7.2.13 and 8.4.1.

IEC 61076-2-111:2025 This part of IEC 61076‑2 describes 4- to 6-way circular connectors with M12 screw-locking with current ratings 8, 12 or 16 A per contact and voltage ratings of 50 V AC / 60 V or 630 V according to their coding, that are typically used for power supply and power applications in industrial premises.

IEC 61757-8-1:2025 defines the terminology, structure, and measurement methods of optical pressure sensors for gases or liquids based on a diaphragm in combination with fibre Bragg gratings (FBGs) as the sensing element. This document also specifies the most important features and characteristics of these fibre optic pressure sensors and defines procedures for measuring these features and characteristics.

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 62351-7:2025 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the remote monitoring of the health and condition of IEDs (Intelligent Electronic Devices), RTUs (Remote Terminal Units), DERs (Distributed Energy Resources) systems and other systems that are important to power system operations. Power systems operations are increasingly reliant on information infrastructures, including communication networks, IEDs, and self-defining communication protocols. Therefore, management of the information infrastructure has become crucial to providing the necessary high levels of security and reliability in power system operations. The telecommunication infrastructure that is in use for the transport of telecontrol and automation protocols is already subject to health and condition monitoring control, using the concepts developed in the IETF Simple Network Management Protocol (SNMP) standards for network management. However, power system specific devices (like teleprotection, telecontrol, substation automation, synchrophasors, inverters and protections) need instead a specific solution for monitoring their health. The NSM objects provide monitoring data for IEC protocols used for power systems (IEC 61850, IEC 60870-5-104) and device specific environmental and security status. As a derivative of IEC 60870-5-104, IEEE 1815 DNP3 is also included in the list of monitored protocols. The NSM data objects use the naming conventions developed for IEC 61850, expanded to address NSM issues. For the sake of generality these data objects, and the data types of which they are comprised, are defined as abstract models of data objects. In addition to the abstract model, in order to allow the integration of the monitoring of power system devices within the NSM environment in this part of IEC 62351, a mapping of objects to the SNMP protocol of Management Information Base (MIBs) is provided. The objects that are already covered by existing MIBs are not defined here but are expected to be compliant with existing MIB standards. For example protocols including EST, SCEP, RADIUS, LDAP, GDOI are not in scope. This edition of IEC 62351-7 cancels and replaces IEC 62351-7 published in 2017. This new edition constitutes a technical revision and includes the following significant technical changes with respect to IEC 62351-7: a) Reviewed and enriched the NSM object data model; b) UML model adopted for NSM objects description; c) SNMP protocol MIBs translation included as Code Components

IEC 60601-2-64:2025 applies to the BASIC SAFETY and essential performance of LIGHT ION BEAM ME EQUIPMENT, hereafter referred to as ME EQUIPMENT, used for treatment of patients. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME EQUIPMENT and to ME SYSTEMS, as relevant. This document, with the inclusion of TYPE TESTS and SITE TESTS, applies respectively to the manufacturer and specified installation aspects of LIGHT ION BEAM ME EQUIPMENT – intended for RADIOTHERAPY in human medical practice, including those in which the selection and DISPLAY of operating parameters can be controlled automatically by PROGRAMMABLE ELECTRONIC SUBSYSTEMS (PESS), – that, in NORMAL USE, deliver a RADIATION BEAM of LIGHT IONS having ENERGY PER NUCLEON in the range 10 MeV/n to 500 MeV/n, and – intended to be • for NORMAL USE, operated under the authority of appropriately licensed or QUALIFIED PERSONS by OPERATORS having the required skills for a particular medical application, for particular SPECIFIED clinical purposes maintained in accordance with the recommendations given in the INSTRUCTIONS FOR USE, • subject to regular quality assurance performance and calibration checks by a QUALIFIED PERSON. IEC 60601-2-64:2025 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: a) harmonization with IEC 60601-1:2005, IEC 60601-1:2005/AMD1:2011 and IEC 60601-1:2005/AMD2:2020; b) harmonization with IEC 62667:2017 for defined terms and definitions; c) address revision to neutrons outside the field of irradiation.

IEC 63409-3:2025 specifies test procedures for confirming the basic operational characteristics of power conversion equipment (PCE) for use in photovoltaic (PV) power systems with or without energy storage. The basic operational characteristics are the capability of the PCE before any limitations due to internal settings are applied to the PCE to meet specific grid support functions or specific behaviours against abnormal changes. This document covers the testing of the following items: a) Steady state characteristics Test procedures to confirm operable range of PCE at steady state condition are described. The operable ranges in apparent power, active power, reactive power, power factor, grid voltage and grid frequency are confirmed according to the test procedures. b) Transient-response characteristics Test procedures to confirm PCE’s response against a change of operational condition are described. This document only considers the changes within normal (continuous) operable ranges. Therefore, the behaviours against abnormal changes and grid support functions are out of the scope and are covered in other parts of this series.

IEC 63584-210:2025 is the OCPP version 2.1. Version 2.1 is an extension of OCPP 2.0.1. OCPP 2.1 has its own JSON schemas, but the schemas are OCPP 2.0.1 schemas that have been extended with optional fields that are used by OCPP 2.1 functionality. With the minor exceptions mentioned below, all application logic developed for OCPP 2.0.1 will continue to work in OCPP 2.1 without any changes. The new features of OCPP 2.1, of course, require new application logic.

IEC 62541-19: 2025 defines an Information Model of the OPC Unified Architecture. The Information Model describes the basic infrastructure to reference from an OPC UA Information Model to external dictionaries like IEC Common Data Dictionary or ECLASS.

IEC 60601-2-57:2023 applies to basic safety and essential performance of equipment incorporating one or more sources of optical radiation in the wavelength range 200 nm to 3 000 nm, with the exception of laser radiation, and intended to create photobiological effects in humans for therapeutic, diagnostic, monitoring, and cosmetic or aesthetic applications; hereafter referred to as light source equipment (ls equipment).

The amendment to EN IEC 60601-2-57 contains the Annexes ZA (Normative references to international publications with their corresponding European publications) and ZZ (Relationship between this European standard and the General Safety and Performance Requirements of Regulation (EU) 2017/745 aimed to be covered). These two Annexes are necessary for the harmonization of the standard to the Regulation (EU) 2017/745.

IEC 62541-16:2025 defines an Information Model. The Information Model describes the basic infrastructure to model state machines. NOTE State Machines were dealt with in IEC 62541‑5:2020, Annex B. In newer versions of IEC 62541‑5 this Annex B was removed and replaced by this document

IEC 60034-30-1:2025 specifies efficiency classes for single-speed electric motors that are rated in accordance with IEC 60034‑1 or IEC 60079‑0 and are rated for operation on a sinusoidal either 50 Hz or 60 Hz, or both voltage supply. The motors within this document: - have a rated power PN from 0,12 kW to 1 000 kW; - have a rated voltage UN from 50 V up to and including 1 000 V; - have 2, 4, 6 or 8 poles; - are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class; NOTE 1 Most motors covered by this document are rated for duty type S1 (continuous duty). However, some motors that are rated for other duty cycles are still capable of continuous operation at their rated power, and these motors are also covered by this document. - are marked with any ambient temperature within the range of –30 °C to +60 °C; NOTE 2 The rated efficiency and efficiency classes are based on 25 °C ambient temperature in accordance with IEC 60034‑2‑1. NOTE 3 Motors exclusively rated for temperatures outside the range – 30 °C and +60 °C are considered to be of special construction and are consequently excluded from this document. NOTE 4 Smoke extraction motors with a temperature class of up to and including 400 °C are covered by this document. - are marked with an altitude up to 4 000 m above sea level. NOTE 5 The rated efficiency and efficiency class are based on a rating for altitudes up to 1 000 m above sea level. This document establishes a set of nominal efficiency values based on supply frequency, number of poles and motor output power. No distinction is made between motor technologies, supply voltage or motors with increased insulation designed specifically for converter operation even though not all motor technologies are capable of reaching the higher efficiency classes (see Table 1). This makes different motor technologies fully comparable with respect to their energy efficiency potential. The efficiency of power-drive systems is not covered by this document. Motor losses due to harmonic content of the supply voltage, losses in cables, filters and frequency-converters, are not covered. Motors with flanges, feet or shafts with mechanical dimensions different from IEC 60072‑1 are covered by this document. Geared motors are covered by this document including those incorporating non-standard shafts and flanges. This document does not apply to the following: - Single-speed motors with 10 or more poles or multi-speed motors. - Motors with mechanical commutators (such as DC motors). - Motors completely integrated into a machine (for example pump, fan and compressor) that cannot be practically tested separately from the machine even with provision of a temporary end-shield and drive-end bearing. This means the motor: a) shares common components (apart from connectors such as bolts) with the driven unit (for example, a shaft or housing) and b) is not designed in such a way as to enable the motor to be separated from the driven unit as an entire motor that can operate independently of the driven unit. That is, for a motor to be excluded from this document, the process of separation shall render the motor inoperative. - Totally enclosed air-over machines (TEAO, IC418), i.e. totally enclosed frame-surface cooled machines intended for exterior cooling by a ventilating means external to the machine. Efficiency testing of such motors can be performed with the fan removed and the cooling provided by an external blow

The amendment to EN IEC 60601-2-22:2020 contains the Annexes ZA (Normative references to international publications with their corresponding European publications) and ZZ (Relationship between this European standard and the General Safety and Performance Requirements of Regulation (EU) 2017/745 aimed to be covered). These two Annexes are necessary for the harmonization of the standard to the Regulation (EU) 2017/745.

IEC 63522-43:2025 This document is used for testing along with the appropriate severities and conditions for measurements and tests designed to assess the ability of specimens to perform under expected conditions of transportation, storage and all aspects of operational use. This document defines a standard test method for evaluation of appropriate materials having appropriate values of tracking resistance.

IEC 60749-24:2025 specifies unbiased highly accelerated stress testing (HAST). HAST is performed for the purpose of evaluating the reliability of non-hermetically packaged solid-state devices in humid environments. It is a highly accelerated test which employs temperature and humidity under non-condensing conditions to accelerate the penetration of moisture through the external protective material (encapsulant or seal) or along the interface between the external protective material and the metallic conductors which pass through it. Bias is not applied in this test to ensure that the failure mechanisms potentially overshadowed by bias can be uncovered (e.g. galvanic corrosion). This test is used to identify failure mechanisms internal to the package and is destructive. This edition includes the following significant technical changes with respect to the previous edition: a) rearrangement of clauses to reposition requirements; b) addition of two notes to the post-test electrical procedures.

IEC 61076-2:2025 establishes uniform specifications and technical information for circular connectors.

IEC 60749-22-1:2025 provides a means for determining the strength and failure mode of a wire bonded to, and the corresponding interconnects on, a die or package bonding surface and can be performed on unencapsulated or decapsulated devices. This test method can be performed on gold alloy, copper alloy, and silver alloy thermosonic (ball and stitch) bonds made of wire ranging in diameter from 15 µm to 76 µm (0,000 6" to 0,003"); and on gold alloy, copper alloy, and aluminium alloy ultrasonic (wedge) bonds made of wire ranging in diameter from 18 µm to 600 µm (0,000 7" to 0,024"). This wire bond pull test method is destructive. It is appropriate for use in process development, process control, or quality assurance. This test method allows for two distinct methods of pulling wires: a) One method incorporates the use of a hook that is placed under the wire and is then pulled. b) One method requires that after the wire be cut, a clamp is placed on the wire connected to the bond to be tested, and this clamp is used to pull the wire. This test method does not include bond strength testing using wire bond shear testing. Wire bond shear testing is described in IEC 60749-22-2. This first edition, together with the first edition of IEC 60749-22-2:2025, cancels and replaces the first edition of IEC 60749-22 published in 2002. This edition includes the following significant technical changes with respect to the previous edition: a) Major update, including new techniques and use of new materials (e.g. copper wire) involving a complete rewrite as two separate subparts (this document and IEC 60749-22-2). This International Standard is to be used in conjunction with IEC 60749-22-2:2025.

IEC 62849:2025 provides performance testing and evaluation methods for the common features of robots for household and similar use, their physical specifications satisfying the following: – height: maximum 1,75 m, – dimensions: maximum 700 mm wide (to be able to fit through doorways), – speed: maximum 1,5 m/s, – floor supported wheeled or wheel-track robots. This document is neither concerned with safety nor with performance requirements. This document is applicable for indoor floor use robots. This document is not applicable to wet and dry surface-cleaning robots or combination of such functions. If different testing and evaluating methods are given in other standards for specific robots, these methods can be considered for priority use. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the title has been changed to "Performance evaluation methods of robots for household and similar use"; b) the scope is more clearly defined and the physical specifications of robots for household and similar use covered by this document are clearly defined; c) new evaluation methods for 6 performance items have been added, including obstacle avoidance, managing a ramp, lighting effects, transition overcome, threshold overcome, energy consumption of robots; d) new structure has been introduced, which provides basic common test methods in each category and can be used by other robotics standards, including the following: 1) mobility, 2) navigation, 3) energy use, 4) effects on environment, 5) other/miscellaneous.

IEC 63382-1:2025 series specifies the management of distributed energy storage systems, composed of electrically chargeable vehicle batteries (ECV-DESS), which are handled by an aggregator/flexibility operator (FO) to provide energy flexibility services to grid operators. IEC 63382-1:2025 describes the technical characteristics and architectures of ECV-DESS, including: – EV charging stations configurations, comprising several AC-EVSEs and/or DC-EVSEs; – individual EVs connected to grid via an EVSE and managed by an aggregator/FO. The focus of this document is on the interface between the FO and the FCSBE and the data exchange at this interface, necessary to perform energy flexibility services (FS). The data exchange between FO and FCSBE typically includes: – flexibility service request and response; – flexibility services parameters; – EV charging station configuration and technical capabilities; – credentials check of parties involved in the flexibility service; – FS execution related notifications; – event log, detailed service record, proof of work. The exchange of credentials has the purpose to identify, authenticate and authorize the actors involved in the flexibility service transaction, to check the validity of a FS contract and to verify the technical capabilities of the system EV + CS, and conformity to applicable technical standards to provide the requested flexibility service. This document also describes the technical requirements of ECV-DESS, the use cases, the information exchange between the EV charging station operator (CSO) and the aggregator/FO, including both technical and business data. It covers many aspects associated to the operation of ECV-DESS, including: – privacy issues consequent to GDPR application (general data protection regulation); – cybersecurity issues; – grid code requirements, as set in national guidelines, to include ancillary services, mandatory functions and remunerated services; – grid functions associated to V2G operation, including new services, as fast frequency response; – authentication/authorization/transactions relative to charging sessions, including roaming, pricing and metering information; – management of energy transfers and reporting, including information interchange, related to power/energy exchange, contractual data, metering data; – demand response, as smart charging (V1G). It makes a distinction between mandatory grid functions and market driven services, taking into account the functions which are embedded in the FW control of DER smart inverters. This document deals with use cases, requirements and architectures of the ECV-DESSs with the associated EV charging stations. Some classes of energy flexibility services (FS) have been identified and illustrated in dedicated use cases: – following a dynamic setpoint from FO; – automatic execution of a droop curve provided by FO, according to local measurements of frequency, voltage and power; – demand response tasks, stimulated by price signals from FO; – fast frequency response. Furthermore, some other more specific flexibility service use cases include: – V2G for tertiary control with reserve market; – V2H with dynamic pricing linked to the wholesale market price; – distribution grid congestion by EV charging and discharging. FS are performed under flexibility service contracts (FSC) which can be stipulated

IEC 60749-22-2:2025 establishes a means for determining the strength of a ball bond to a die or package bonding surface and can be performed on pre-encapsulation or post-encapsulation devices. This measure of bond strength is extremely important in determining two features: a) the integrity of the metallurgical bond which has been formed, and b) the quality of ball bonds to die or package bonding surfaces. This test method covers thermosonic (ball) bonds made with small diameter wire from 15 µm to 76 µm (0,000 6" to 0,003"). This test method can only be used when the bonds are large enough to allow for proper contact with the shear test chisel and when there are no adjacent interfering structures that would hinder the movement of the chisel. For consistent shear results the ball height will be at least 4,0 µm (0,000 6 ") for ball bonds, which is the current state of the art for bond shear test equipment at the time of this revision. This test method can also be used on ball bonds that have had their wire removed and on to which a second bond wire (typically a stitch bond) is placed. This is known as "stitch on ball" and "reverse bonding". See Annex A for additional information. The wire bond shear test is destructive. It is appropriate for use in process development, process control, or quality assurance, or both. This test method can be used on ultrasonic (wedge) bonds, however its use has not been shown to be a consistent indicator of bond integrity. See Annex B for information on performing shear testing on wedge bonds. This test method does not include bond strength testing using wire bond pull testing. Wire bond pull testing is described in IEC 60749-22-1. This first edition, together with the first edition of IEC 60749-22-1, cancels and replaces the first edition IEC 60749-22 published in 2002. This International Standard is to be used in conjunction with IEC 60749-22-1:2025. This edition includes the following significant technical changes with respect to the previous edition: a) Major update, including new techniques and use of new materials (e.g. copper wire) involving a complete rewrite as two separate subparts (this document and IEC 60749‑22‑1).

IEC 60079-29-0:2025 specifies general requirements, test methods and acceptance criteria that apply to flammable, oxygen and toxic gas detection equipment intended to detect gases and vapours and to provide an indication, alarm or other output function for personnel or property protection in industrial and commercial applications. This document applies to the following gas detection equipment: – Gas detection equipment Type "FL" intended for the detection of flammable gases: • Type FL-Group I, in mines susceptible to firedamp; • Type FL-Group II, in locations other than mines susceptible to firedamp; and • Type FL-OP, open path gas detection equipment for flammable gases. – Gas detection equipment Type "O2" intended for the detection of Oxygen: • Type O2-DE, detection of oxygen deficiency or oxygen enrichment; and • Type O2-IN, inertisation as measuring function for explosion protection. – Gas detection equipment Type "TX" intended for the detection of toxic gases: • Type TX-SM, detection in areas for safety monitoring applications and typically using alarm signalling; • Type TX-HM, occupational exposure measurement in the region of occupational exposure limit values; and • Type TX-OP, open path gas detection equipment for toxic gases. This document is not applicable to equipment: – used for medical applications; – used only in laboratories for analysis or measurement; – used only for process monitoring or control purposes (such as a gas analyser); – used in the domestic environment; – used in environmental air pollution monitoring; – used for flue gas analysis; – used for sampling systems external to the gas detection equipment; – with samplers and concentrators such as sorbents or paper tape having an irreversible indication; – consisting of a passive optical receiver without a dedicated optical source; – equipment within the scope of IEC 60335-2-40 and IEC 60335-2-89. This first edition of IEC 60079-29-0 cancels and replaces the second edition of 60079-29-1 published in 2016 and its Amendment 1:2020, and the first edition of IEC 60079-29-4 published in 2009. In addition, IEC 60079-29-0 Type TX-SM cancels and replaces Type SM of the first edition of IEC 62990-1.

IEC 60749-7:2025 specifies the testing and measurement of water vapour and other gas content of the atmosphere inside a metal or ceramic hermetically sealed device. The test is used as a measure of the quality of the sealing process and to provide information about the long-term chemical stability of the atmosphere inside the package. It is applicable to semiconductor devices sealed in such a manner but generally only used for high reliability applications such as military or aerospace. Of particular interest is the measurement of the primary sealing gases (or lack thereof), the moisture content, the presence of bombing gases that are indicative of non-hermeticity (e.g. helium), oxygen to argon ratio indicative of room air ~ 20 to 1 (± 10 %), dissimilar concentration of internally sealed gases (e.g. nitrogen, helium) than originally sealed in the device package, the presence of leak test fluid (i.e. fluorocarbon, helium, air), and all other gases to determine if the device meets the specified moisture, hermeticity and other criteria. Also of interest is the measurement of all the other gases since they reflect upon the quality of the sealing process and provide information about the long-term chemical stability of the atmosphere inside the device. The presence of leak test fluorocarbon vapour in the internal gas analysis (IGA) is an indication of failure to meet leak test requirements of IEC 60749‑8. This test is destructive. This edition includes the following significant technical changes with respect to the previous edition: a) This document has been re-written and rearranged to align with the text of MIL-STD-883, Method 1018.10. b) Additional detail has been provided in the calibration requirements.

IEC 63616:2025 relates to a conductivity measurement method of thin metal films at microwave and millimeter-wave frequencies. This method has been developed to evaluate the conductivity of a metal foil used for adhering to a substrate or the interfacial conductivity of a metal layer formed on a dielectric substrate. It uses higher-order modes of a balanced-type circular disk resonator and provides broadband conductivity measurements by using a single resonator.

IEC 61643-21:2025 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are intended to be connected to telecommunications and signalling networks, and equipment rated up to 1 000 V RMS and 1 500 V DC. These telecommunications and signalling networks can also provide power on the same line, e.g. Power over Ethernet (PoE). Performance and safety requirements, tests and ratings are specified in this document. These devices contain at least one voltage-limiting component (clamping or switching) and are intended to limit surge voltages and divert surge currents. This second edition cancels and replaces the first edition published in 2000, Amendment1:2008 and Amendment 2:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) New structure of IEC 61643-21 based on IEC 61643-01:2024; b) Several safety requirements based on IEC 61643-01:2024 have been added. This International Standard is to be used in conjunction with IEC 61643-01:2024.

IEC 63437:2025 specifies the essential characteristics of off grid and unreliable grid refrigerating appliances for domestic and similar use or light commercial use, cooled by internal natural or forced air convection. It defines input voltage supply signals for appliances designed for unreliable grid and off grid conditions. An unreliable grid condition can be the result of disturbances on the electricity supply, such as power outages, or issues with power quality, such as voltage spikes and surges, that could cause performance challenges to refrigerating appliances. An off grid supply, in this context, for example is generated by a solar panel or a stand-alone solar home system that is not connected to the power grid. This document simulates the power characteristics in off grid and unreliable grid conditions but does not specify requirements or test procedures to assess performance of generators, solar panels, solar home system or any other system generating a supply signal. The supply signals defined in this document can also be used for evaluation of the performance of other refrigerating appliances such as medical or laboratory appliances, professional storage refrigerators or freezers, refrigerated display cabinets, beverage coolers or ice cream freezers. This document specifies the test methods for measuring the functional performance characteristics and requirements. This document does not apply to refrigerating appliances designed for a good quality and stable electricity grid and refrigerating appliances utilising fuelled absorption cooling technology. This document is applicable to any refrigerating appliance for domestic or light commercial use that has a rated performance to properly operate off grid or under unreliable grid operating conditions resisting power interruptions and supply variations. Off grid and unreliable grid refrigerating appliances are appliances intended to for use with standalone or intermittent or distorted electrical mains. Electrical mains supply is assumed to be alternating current (AC) for unreliable grid or direct current (DC) for off grid. This document is also applicable to hybrid refrigerating appliances.
