IEC 61300-2-44: 2024 spécifie un essai pour déterminer l’influence de flexions sous une charge de traction du serre-câble des dispositifs d’interconnexion fibroniques ou des composants fibroniques. L’objectif est de simuler le nombre de flexions généralement expérimenté en service. L’essai est appliqué sur des câbles à fibre unique et des câbles à fibres multiples. Cette quatrième édition annule…

IEC 62836:2024 provides an efficient and reliable procedure to test the internal electric field in the insulating materials used for high-voltage applications, by using the pressure wave propagation (PWP) method. It is suitable for a planar and coaxial geometry sample with homogeneous insulating materials of thickness larger or equal to 0,5 mm and an electric field higher than 1 kV/mm, but it is…

L’IEC 62836 :2024 fournit une procédure efficace et fiable pour évaluer le champ électrique interne dans les matériaux isolants utilisés pour les applications à haute tension, par la méthode de l'onde de pression (PWP). Cette méthode convient aux échantillons à géométrie plane et coaxiale constitués de matériaux isolants homogènes d'une épaisseur supérieure ou égale à 0,5 mm et aux…

IEC 60676:2024 This document specifies the basic test procedures, conditions and methods for establishing the main performance parameters and the main operational characteristics of furnaces for direct arc heating, forming arcs between the electrode and metal, such as electric arc furnaces using alternating current (EAF AC) or direct current (EAF DC), and ladle furnaces (LF), with rated power…

L’IEC 60676:2024 spécifie les procédures, les conditions et les méthodes d'essai fondamentales pour établir les principaux paramètres de performance et les principales caractéristiques de fonctionnement des fours qui utilisent le chauffage par arc direct, qui forme des arcs entre l'électrode et le métal, tels que les fours à arc électrique à courant alternatif (EAF AC, Electric Arc…

This document specifies how uncompressed 2D image and video data is carried in files in the family of standards based on the ISO base media file format (ISO/IEC 14496-12). This includes but is not limited to monochromatic data, colour data, transparency (alpha) information and depth information. The primary goal of this document is to allow exchange of uncompressed video and image data while…

This document applies to nuclear power plants with water cooled reactors. This document does not apply to earthquakes stronger than the design basis earthquake. This document specifies guidance on the actions to be taken in preparation for and following an earthquake at a nuclear power plant. This document is intended to be used as a guideline for decision making regarding continued operation,…
