Analyse des gaz — Conversion des données de composition de mélanges gazeux
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…
Corrosion protection of steel structures by protective paint systems — Assessment of, and acceptance...
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…
Protection contre la corrosion des structures en acier par systèmes de peinture — Évaluation et crit...
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…
Information technology - Coding of audio-visual objects - Part 34: Syntactic description language
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…
Semiconductor devices – Estimation method for lifetime conversion from “PART” to “SYSTEM”
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.
Plastics — Test method for estimation of the short chain branching distribution of semicrystalline e...
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…
