IEC 62425:2025 is applicable to safety-related electronic systems (including subsystems and equipment) for railway signalling applications. This document applies to generic systems (i.e. generic products or systems defining a class of applications), as well as to systems for specific applications. The scope of this document, and its relationship with other IEC and CENELEC standards, are shown in…

This document provides guidance and requirements for the maintenance and the use of triaryl phosphate esters as fire-resistant fluids for turbine control, other hydraulic systems in power generation and fire-resistant turbine fluids. This document is applicable to fluids under the HFDR category defined in ISO 6743-4 and under the TCD, TSD and TGD categories defined in ISO 6743-5.

Le présent document fournit des recommandations et des exigences pour la maintenance et l’utilisation de fluides difficilement inflammables à base de phosphates de tris(aryle) utilisés comme fluides de régulation de turbines ou dans les autres systèmes hydrauliques pour la production d’énergie, ainsi qu’aux fluides difficilement inflammables pour turbines. Ce document est applicable aux fluides…

This document provides information on how electrical designers determine the allowable limit of electric wire in space condition. This document provides the basis of the allowable wire current and its derated value in published technical standards. This document also provides the results of comparing the derated wire current values depending on the number of bundled wires, wire type and…

IEC 63455:2025 specifies the 4b/10b line code with error correction for dependable multimedia data transmission, especially for real-time communications even in noisy environments, such as IoT devices, wearable devices, sensor networks, robotics, and spacecraft. This document corresponds to the functions specified in layer 1 to layer 2 of the OSI reference model (ISO/IEC 7498). This document…

IEC 63455:2025 spécifie le code en ligne 4b/10b avec correction d’erreurs pour la transmission fiable de données multimédias, en particulier pour les communications en temps réel, même dans des environnements bruyants, tels que les dispositifs IdO, les dispositifs portatifs, les réseaux de capteurs, la robotique et les engins spatiaux. Il correspond aux fonctions spécifiées dans les couches 1 à 2…

IEC TR 61857-2:2025 gives guidelines to identify the appropriate test method for the evaluation of a proposed electrical insulation system (EIS). Some of the standards evaluate the EIS using one stress factor which is thermal. Other standards evaluate the thermal stress factor with adjustments to the conditioning applied prior to the diagnostic testing to simulate applications in air. A third…

Scope 1.1 These requirements cover the fire safety aspects of industrial trucks with internal-combustion engines, such as tractors, platform-lift trucks, fork-lift trucks, and other specialized vehicles for industrial use. These requirements do not cover other possible safety aspects of such equipment. 1.2 These requirements do not cover farm or road vehicles or automotive vehicles for…

This document describes a digital twin for monitoring and controlling the semiconductor ingot growth process. The use case is analysed and designed using the ISO 23247 series. The result is a systematic view of the use case implementation and a high-level design of the digital twins, which can be directly implemented using the readily available tools and languages, including those supported by…

Le présent document présente les exigences applicables à la conception, à la fabrication et à l'agencement de gares de racleurs terrestres et en mer assurant l'accès à des conduites, et permettant le lancement et la réception de racleurs, d'outils d'inspection et d'autres équipements ayant vocation à passer à l'intérieur desdites conduites, ainsi qu'à la…
