L'IEC 61010-2-033:2023 spécifie les exigences de sécurité particulières pour les multimètres portatifs pour usage domestique et professionnel, capables de mesurer la tension réseau. Les multimètres portatifs sont des instruments de mesure multifonctions et avec plusieurs plages, destinés à mesurer la tension et d’autres grandeurs électriques telles que la résistance ou le courant. Ils ont…

IEC 60404-8-1:2023 specifies minimum values for the principal magnetic properties of, and dimensional tolerances for, technically important permanent magnet (magnetically hard) materials. For information purposes only, this document provides values for the densities of the materials and the ranges of their chemical compositions. This fourth edition includes the following significant technical…

This document describes descriptive ontology for finguistic and cognitive engineering (DOLCE) as an ontology that is conformant to the requirements specified for top-level ontologies in ISO/IEC 21838-1. This document describes DOLCE as a resource designed to support ontology design, ontology integration, and semantic integration of heterogeneous information systems. The following are within the…

This document describes TUpper as a resource designed to support ontology design, ontology integration, automated reasoning, and semantic integration of heterogeneous information systems. The following are within the scope of this document: —     definitions…

This document specifies the measurements of particle size distribution and concentration of suspended particles, ranging from 40 nm to 100 µm, using tunable resistive pulse sensing (TRPS). This document provides a comprehensive overview of the methodologies that are applied to achieve reproducible and accurate TRPS measurement results. This document also includes best practice considerations,…

IEC 60794-1-111: 2023 définit la procédure d'essai en vue de déterminer la capacité d'un câble à fibres optiques à résister à la courbure autour d'un mandrin d'essai. L'objectif principal de cette procédure est de mesurer la variation de l’affaiblissement lorsque le câble est courbé autour d'un mandrin d'essai. L’objectif secondaire est d'évaluer si le…

IEC 60794-1-306: 2023 describes test procedures to verify the mechanical and functional integrity of the fibre ribbon structure. The test determines the capability of the ribbon to withstand torsion without delamination between optical fibre and ribbon bonding agent. This document applies to optical fibre ribbons in optical cables for use with telecommunication equipment and devices employing…

IEC 60794-1-306: 2023 décrit les procédures d'essais en vue de vérifier l'intégrité mécanique et fonctionnelle de la structure en rubans des fibres. L'essai vise à déterminer la capacité du ruban à résister à la torsion sans décollement interlaminaire entre la fibre optique et l'agent de fixation du ruban. Le présent document s’applique aux rubans de fibres optiques dans les…
