IEC TS 62607-6-36:2026, which is a Technical Specification, establishes a standardized method to determine the key control characteristic
• reduction status
for graphene oxide (GO) and reduced graphene oxide (rGO) by
• ultraviolet-visible spectroscopy (UV-Vis).
The reduction status is not a quantitative value, but rather a compilation (table) of six parameters extracted from UV-Vis absorption spectra. These six parameters can be obtained from GO and rGO as follows:
(1) the peak location of GO, (2) the shoulder peak of GO, (3) the full width at half maximum (FWHM) of the main absorption peak of GO, (4) the peak location of rGO, (5) FWHM of the main absorption peak of rGO and (6) the spectral peak shifts between GO and rGO.
• The method is applicable to the characterization of GO and rGO materials (where rGO is obtained from the corresponding GO) produced by different reduction techniques, as well as to commercial products in solution or film form.
• Individual GO or rGO materials can also be characterized, but only partial parameters can be obtained. Specifically, peak location, FWHM, and shoulder peak can be measured from each GO or rGO material, while peak shift requires both GO and its corresponding rGO for comparison.
• The method is suitable for quality assurance and for monitoring the reduction process during the production of rGO.
• The method does not provide full chemical analysis. Complementary techniques can be required beyond the UV-Vis spectral features.

IEC 61514:2026 specifies tests designed to determine the static and dynamic performance of single-acting or double-acting analogue positioners. The tests apply to positioners which receive standard analogue input signals (as specified in IEC 60381-1, IEC 60381-2 and IEC 60382) and have a pneumatic output. Positioners with pulsed or digital input signals, positioners with digital controllers and positioners with pulsed outputs are outside the scope of this document. Testing is conducted either on a positioner alone, independently of an actuator, or on a positioner mounted and connected to a specific actuator, as a combined unit. The text makes clear where different approaches are required. The methods of evaluation given in this document are intended for use by manufacturers to determine the performance of their products, and by users, or independent testing establishments, to verify manufacturers' performance specifications. The closest liaison between the evaluating body and the manufacturer is indispensable during the tests, including the possibility for the manufacturer to influence the test programme based on the manufacturer's specifications for the instrument and comment on both the test programme and the results. This document is intended to provide definitions of positioner elements, actions, and characteristics, to specify uniform methods of measuring performance errors and effects of influence quantities on those characteristics, and to describe methods of reporting and evaluating the results of the measurement data obtained. The test conditions described in this publication (for example range of ambient temperatures and power supply) relate to conditions which commonly arise in use. Consequently, the values specified are used where no other values are specified by the manufacturer or user. If other values are used, they will be stated. It is recognized that the manufacturer's specifications and instructions for installation and operation apply during all steps. The tests specified in this document are not necessarily sufficient for instruments specifically designed for unusually arduous conditions. Conversely, a reduced series of tests can serve adequately for instruments designed to perform within a more limited range of conditions. When a full evaluation, in accordance with this document, is not required or possible, only the tests which are required are performed and the results reported in accordance with the relevant parts of this document. In such cases, the test report will state that it does not cover the full number of tests specified herein. This second edition cancels and replaces the first edition published in 2000.

- persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
- children playing with the appliance.
Attention is drawn to the fact that
- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
- in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to
- pumps (IEC 60335-2-41);
- luminaires for aquariums (IEC 60598-2-11);
- luminaires for swimming pools and similar applications (IEC 60598-2-18);
- appliances intended exclusively for professional use;
- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

IEC TS 62001-3:2026 provides in-depth consideration regarding three particularly important aspects of design, which are also mentioned elsewhere in other parts of the IEC 62001 series, which are: AC network impedance modelling, the treatment of pre‑existing harmonics in performance and rating calculations, and harmonic interaction across converters (cross-modulation).
This document concentrates on passive AC filter technology and line-commutated high-voltage direct current (HVDC) converters, but much of the content is equally relevant to VSC converter technology. Where there is a distinction, this is indicated in the text.
The scope of this document covers AC side filtering for the frequency range of interest in terms of harmonic distortion and audible frequency disturbances. It excludes filters specifically designed to be effective in the PLC and radio interference spectra.

ISO PAS 15118-23:2026 This document specifies conformance tests in the form of an abstract test suite (ATS) for a system under test (SUT) that implements an electric-vehicle communication controller (EVCC) or a supply-equipment communication controller (SECC) for all direct current (DC)-specific requirements specified in ISO 15118-20 that are associated to the DC charging type. These conformance tests specify the testing of capabilities and behaviours of an SUT, as well as checking what is observed against the conformance requirements specified in ISO 15118-20 and against what the implementer states the SUT implementation's capabilities are.
The capability tests within the ATS check that the observable capabilities of the SUT are in accordance with the static conformance requirements defined in ISO 15118-20. The behaviour tests of the ATS examine an implementation as thoroughly as practical over the full range of dynamic conformance requirements defined in ISO 15118-20 and within the capabilities of the SUT.
The test architecture for this document is inherited from the test architecture specified in ISO 15118-21. If further aspects for DC-specific requirements are necessary, they extend this architecture and are specified in this document. The abstract test cases in this document are described leveraging this test architecture and are specified in descriptive tabular format covering the ISO/OSI layer 3 to 7 (network to application layers).
In terms of coverage, this document only covers normative sections and requirements in ISO 15118-20. This document can additionally refer to specific tests for requirements on referenced standards (e.g. IETF RFCs, W3C Recommendation, etc.) if they are relevant in terms of conformance for implementations according to ISO 15118-20. However, it is explicitly not intended to widen the scope of this conformance specification to such external standards, if it is not technically necessary for the purpose of conformance testing for ISO 15118-20. Furthermore, the conformance tests specified in this document do not include the assessment of performance nor robustness or reliability of an implementation. They cannot provide judgments on the physical realization of abstract service primitives, how a system is implemented, how it provides any requested service, nor the environment of the protocol implementation. Furthermore, the abstract test cases defined in this document only consider the communication protocol and the system's behaviour defined ISO 15118-20. Power flow between the EVSE and the EV is not a prerequisite for the test cases specified in this document.
