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…

Le présent document définit les grandeurs suivantes qui sont couramment utilisées pour exprimer la composition des mélanges gazeux: —     fraction et concentration molaires; —     fraction et concentration massiques; —     fraction et concentration volumiques. Pour ces grandeurs de composition, le présent document spécifie des méthodes permettant: —     une conversion entre différentes grandeurs…

Le présent document spécifie des modes opératoires permettant d'évaluer la résistance des systèmes de peinture lorsque ces derniers sont soumis à des incisions en quadrillage ou en croix de Saint André atteignant le subjectile. Il n'est applicable que si la méthode d'essai (incisions par quadrillage ou en croix de Saint André) ainsi que le classement des résultats conformément à la…

This document specifies a syntactic description language for describing the structure of binary data. It covers the representation of an SDL specification in plain text, the syntax of the SDL and the semantic rules of the SDL. In scenarios where the usage or interpretation of the SDL are ambiguous or undefined, this document attempts to specify whether such a scenario is considered an invalid SDL…

IEC TR 63571:2025 describes a method to calculate “SYSTEM”-level lifetime from “PART”-level lifetime. It presents a general mathematical theory and simple calculation examples for educational purposes. Of the elements related to “SYSTEM”-level lifetime, software-related elements such as diagnostics are outside the scope of this document.

This document specifies a test method for the estimation of the short chain branching distribution of semicrystalline ethylene 1-olefin copolymers by successive self-nucleation and annealing (SSA) with conventional, high performance and fast differential scanning calorimetry. This document is applicable to the estimation of the short chain branching distribution of raw materials of…

This document specifies two methods for the determination of co-monomer contents of polyethylene products by solution state 13C-NMR spectrometry (nuclear magnetic resonance spectrometry): —     Method A: inverse gated decoupling method; —     Method B: insensitive nuclei enhanced by polarization transfer method. This document is applicable to copolymers of ethylene having a content of other 1-…

IEC 60730-2-23:2025 EXV contains both the international standard and its extended version (EXV). 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 60730-2-23:2025 EXV includes the content of the references made to IEC 60730-1:2022. IEC 60730-2-23:2025 applies to the safety of electrical,…
