IEC 62057-1:2023 s'applique aux bancs d'essai stationnaires des compteurs d'énergie électrique (MTU, Meter Test Units) installés en permanence dans les laboratoires, utilisés pour les essais et l'étalonnage des compteurs d'électricité, en particulier pour leurs essais de type, de réception et de vérification. Elle couvre les exigences relatives aux MTU automatisés pour…

Le présent document offre un cadre transparent pour déclarer les choix de mode opératoire visant à déterminer les facteurs d’énergie primaire (PEF) ainsi que les coefficients d’émission de CO2 de l’énergie livrée aux bâtiments et de l’énergie exportée par les bâtiments, tels que décrits dans l’ISO 52000-1. Il n’inclut pas de considérations concernant d’autres sujets, notamment les déchets…

This document provides a transparent framework for reporting on the choices related to the procedure to determine primary energy factors (PEFs) and CO2 emission coefficients for energy delivered to and exported from the buildings as described in ISO 52000-1. It does not include considerations on other topics, e.g. nuclear waste, atmospheric particulate matter, deforestation, food and bioenergy…

IEC 61158-4-21:2023 describes: procedures for the timely transfer of data and control information from one data link user entity to a peer user entity, and among the data link entities forming the distributed data link service provider; procedures for giving communication opportunities based on ISO/IEC/IEEE 8802‑3 MAC, with provisions for nodes to be added or removed during normal operation;…

IEC 61158-4-24:2023 provides procedures for the timely transfer of data and control information from one data-link user entity to a peer user entity, and among the data-link entities forming the distributed datalink service provider; procedures for giving communications opportunities to all participating DL-entities (DLEs), sequentially and in a cyclic manner for deterministic and synchronized…

IEC 61158-6-26:2023 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 26 fieldbus. The term "time-critical" is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level…

IEC 60747-5-16:2023 specifies the measuring method of flat-band voltage of single GaN-based light emitting diode (LED) die or package without phosphor, based on the photocurrent (PC) spectroscopy. White LEDs for lighting applications are out of the scope of this part of IEC 60747.

IEC TS 63384-1:2023 provides guidance for power system stability control framework design. It covers the uniform use of terms and definitions, general objectives and principles for power system stability control, the classification of power system stability control, and the framework combining several types of stability controls in a coordinated and cost-effective (risk-based) manner. In…

L'IEC 61158-6-26:2023 donne les éléments communs visant à assurer les communications de messagerie de base à temps critique et à temps non critique entre les programmes d’application d’un environnement d’automatisation et d’un matériel spécifique au bus de terrain de type 26. Le terme "à temps critique" est utilisé pour indiquer la présence d’une fenêtre temporelle, dans laquelle…
