L’IEC 61158-4-28:2023 fournit un moyen de connexion des appareils par l’intermédiaire d’un réseau maillé partiel, de telle sorte que la plupart des défaillances d’une interconnexion entre deux appareils puissent être contournées. Dans la pratique courante, les appareils sont interconnectés d’une manière hiérarchique non redondante reflétant les besoins de l’application.

IEC 61158-5-27:2023 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 27 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…

L’IEC 61158-5-27:2023 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 27. Le terme "à temps critique" est utilisé pour indiquer la présence d’une fenêtre temporelle, dans laquelle il est…

IEC 61784-2-19:2023 defines extensions of Communication Profile Family 19 (CPF 19) for Real-Time Ethernet (RTE). CPF 19 specifies a Real-Time Ethernet (RTE) communication profile (CP) and related network components based on the IEC 61158 series (Type 27), ISO/IEC/IEEE 8802-3 and other standards.

L’IEC 61784-2-19:2023 définit les extensions de la famille de profils de communication 19 (CPF 19) pour Ethernet en temps réel (RTE). La CPF 19 spécifie un profil de communication (CP) Ethernet en temps réel (RTE, Real-Time Ethernet) et des composants de réseau associés basés sur la série IEC 61158 (Type 27), l’ISO/IEC/IEEE 8802-3 et d’autres normes.

IEC 61196-1-123:2023 defines the test method to determine the attenuation constant of radiating coaxial communication cables that are intended for use in wireless communication systems such as tunnels, railways, highways, subways, elevators and other confined areas in which conventional antenna transmission is not satisfactory or even impossible.

This document specifies a safety information system for tanks made by combining several elements onto a single marking to communicate health and hazard safety information and information in case of an emergency for the purpose of accident prevention. The organization's risk assessment will determine when and where this safety information system for tanks will be used. Possible applications…

This document specifies the methods and techniques for leak tightness assessment of a metallic component at high temperature by measuring its total leakage rates in a vacuum chamber with a tracer gas leak detector and high-pressure helium gas or the gas mixture flowing out of the component as tracer gas during its thermal and pressure cycles at its operating conditions. The minimum detectable…

This document specifies the requirements and method used to determine the volatile matter of solid biofuels. It is intended for persons and organisations that manufacture, plan, sell, erect or use machinery, equipment, tools and entire plants related to solid biofuels, and for all persons and organisations involved in producing, purchasing, selling and utilizing solid biofuels.
