This document defines the model and command set extensions to facilitate operation of zoned block devices. The clauses in this document, implemented in conjunction with the applicable clauses of SPC-6 and SBC-5, specify the standard command set for zoned block devices.

IEC TR 63484:2024 information about fungal growth on the outer sheath of optical fibre cables and on the inner components of the cable. It also provides guidance for specifying fungus resistance performance of optical cable outer sheath and internal cable components, including recommendations for fungus resistance test method as well as evaluation after test. This document applies to optical…

IEC TS 63331:2024 applies to electric dishwashers for household and similar use that are supplied with hot and/or cold water. This document deals with measurement procedures regarding the reduction of microbial contamination resulting from the use of electric dishwashers for household and similar use. This document specifies methods that enable reproducible measurements. These derived…

IEC 61196-1-113:2024 applies to coaxial communications cables. It specifies a test method for determining the attenuation constant of coaxial cables for use in communications systems. The test is applicable preferably at frequencies ≥5 MHz but also for lower frequencies if the magnitude of the complex characteristic impedance is approximately equal to the nominal characteristic impedance of the…

IEC 60308:2024 deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control system, such as sequence control tasks, safety and provision for the actuating energy. The following systems are included, speed, power, opening, water level and flow control for all turbine types;…

IEC 60308:2024 traite de la définition et des caractéristiques des systèmes de régulation. Elle n'est pas limitée aux tâches effectives de régulation, mais inclut également d'autres tâches qui peuvent être assignées à un système de régulation, telles que les tâches de commande séquentielle, de sécurité, d'alimentation en énergie de manœuvre. La présente norme couvre les systèmes…

IEC TS 62271-319:2024 is applicable to alternating current circuit-breakers with intentional non-simultaneous pole operation designed for indoor or outdoor installations and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. This document provides additional ratings and type tests to be conducted for this type of circuit-breaker and is intended to be used in…

Le présent document fournit les méthodes d'essai des formulations de ciments pour puits afin de déterminer les variations de dimensions au cours du processus de vieillissement (hydratation du ciment), à pression atmosphérique et élevée, ainsi que l'expansion dans un environnement de confinement à température et pression élevées.

This document provides guidelines for the design, construction, and inspection of concrete-filled steel tubular (CFST) hybrid structures. These structures can be used as main structural components like columns, girders, piers, or arches in buildings, bridges, especially in high-rise structures, long-span spatial structures, and large-scale bridges. CFST hybrid structures can employ CFST members…

This document provides the methods for the testing of well cement formulations to determine the dimension changes during the curing process (cement hydration) at atmospheric and elevated pressure and the stress generated by expansion in a confined environment under elevated temperature and pressure.
