Fibre optic interconnecting devices and passive components - Basic test and measurement procedures -...
IEC 61300-2-44:2024 specifies a test to determine the influence of flexing under tensile load of the strain relief of fibre optic interconnecting devices or components. The intention is to simulate the number of flexing cycles which would typically be experienced during service life. This test is applied to both single fibre cable and multiple fibre cable. This fourth edition cancels and replaces…
Dispositifs d'interconnexion et composants passifs fibroniques - Procédures fondamentales d...
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…
Measurement of internal electric field in insulating materials - Pressure wave propagation method
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…
Mesurage du champ électrique interne dans les matériaux isolants - Méthode de l'onde de pressio...
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…
Industrial electroheating equipment - Test methods for direct arc furnaces
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…
Plastics — Biobased content — Part 4: Determination of biobased mass content
This document specifies a method of determining the biobased mass content in plastics products, based on the radiocarbon analysis and elemental analysis.
This document is applicable to plastic products and plastic materials, polymer resins, monomers or additives, which are made from biobased and/or fossil-based constituents.
This method can be applied provided that the plastic product contains…
