IEC 61754-36:2025 defines the standard mechanical interface dimensions for the type SAC family of connectors.

This document provides background information, methods and examples of calculating contributions to carbon stored in wood-based products (harvested wood products, HWP), including storage resulting from HWPs in landfill and bio-CCS, as defined in ISO 13391-1:2025. It includes background to the tier 1 HWP coefficients for various wood-based product categories defined in ISO 13391-1:2025.

This document specifies the method for selected area electron diffraction (SAED) analysis using a transmission electron microscope (TEM) to analyse thin crystalline specimens. This document applies to test areas of micrometres and sub-micrometres in size. The minimum diameter of the selected area in a specimen which can be analysed by this method is restricted by the spherical aberration…

IEC 60730-2-8:2025 applies to electrically operated water valves • for use in, on, or in association with equipment for household appliance and similar use; NOTE 1 Throughout this document, the word "equipment" means "appliance and equipment" and "control" means "electrically operated water valve". EXAMPLE 1 Electrically operated water valves for…

This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60730-2-8:2025 EXV includes the content of the references made to IEC 60730-1:2022. IEC 60730-2-8:2025 applies to electrically operated water valves…

IEC 61000-2-9: 2025 defines the high-altitude electromagnetic pulse (HEMP) environment that is one of the consequences of a high-altitude nuclear explosion. There are two cases of nuclear detonations: - high-altitude nuclear explosions; - low-altitude nuclear explosions. For civil systems, the most important case is the high-altitude nuclear explosion. In this case, the other effects of the…

This document defines the following quantities commonly used to express the composition of gas mixtures: —     amount fraction and concentration; —     mass fraction and concentration; —     volume fraction and concentration. For these quantities of composition, this document specifies methods for: —     conversion between different quantities; —     conversion between different state conditions…

This document specifies a test method for measuring in situ the sound absorption coefficient of road surfaces for the one-third octave band frequencies ranging from 250 Hz to 1 600 Hz under normal incidence conditions. If necessary for practical applications the diameter of the tube can be reduced to 80 mm. This will increase the upper boundary of the frequency range to 2 000 Hz one-third octave…

This document specifies procedures for assessing the resistance of paint systems when a cut in the form of a right-angle lattice pattern (cross-cut) or in the form of an X (X-cut) is made into the paint, penetrating through to the substrate. This document is only applicable if the cross-cut or X-cut test method is specified, together with the rating from the appropriate rating scale. This…
