This document provides general information about coding efficiency measurement practices for video coding. This document does not provide recommendations for evaluating video quality; it describes the practices that have recently been followed for coding efficiency experiments conducted during work to develop video coding standards.

Le présent document spécifie une méthode d’examen par ressuage utilisée pour localiser des discontinuités, telles que fissures, replis, plis, porosités et manque de liaison, ouvertes et débouchant à la surface du matériau à examiner, à l’aide d’une lumière blanche ou d’un rayonnement UV-A (365 nm). Cette méthode est principalement appliquée aux matériaux métalliques mais peut également être…

This document specifies a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and lack of fusion, which are open to the surface of the material to be tested using white light or UV-A (365 nm) radiation. It is mainly applied to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and not…

This document specifies the application layer, the payload of messages, and parameter groups for equipment other than brakes and running gears, to ensure the interchange of digital information between road vehicles with a maximum authorized total mass greater than 3 500 kg and their towed vehicles, including communication between towed vehicles. This document supports the parameters and message…

IEC 61557-12:2018+A1:2021 specifies requirements for power metering and monitoring devices (PMD) that measure and monitor the electrical quantities within electrical distribution systems, and optionally other external signals. These requirements also define the performance in single- and three-phase AC or DC systems having rated voltages up to 1 000 V AC or up to 1 500 V DC. These devices are…

L'IEC 61557-12:2018+A1:2021 spécifie des exigences relatives aux dispositifs de comptage et de surveillance du réseau électrique (PMD) qui mesurent et surveillent les grandeurs électriques dans les réseaux de distribution électrique et, facultativement, d’autres signaux externes. Ces exigences définissent également les performances dans les réseaux alternatifs ou continus monophasés et…

Le présent document spécifie les principes et les exigences concernant la détermination des émissions de gaz à effet de serre (GES) provenant de sources spécifiques à chaque secteur, telles que les industries qui produisent de l’acier et du fer, du ciment, de l’aluminium, de la chaux et des ferro-alliages. Le présent document spécifie les définitions et les exigences applicables aux parties de la…
