Caractérisation de la texture d'un revêtement de chaussée à partir de relevés de profils de la ...
Le présent document décrit les méthodes disponibles pour effectuer une analyse spectrale d’un profil de surface de chaussée. Il définit une méthode permettant d’analyser la fréquence spatiale (ou la longueur d’onde de texture) de profils de surface bidimensionnels qui décrivent l’amplitude de texture d’un revêtement de chaussée en fonction de la distance le long d’une trajectoire rectiligne ou…

Guideline for the system design of HVDC converter stations with line-commutated converters
IEC TR 63127:2019+AMD1:2024 CSV focuses on the system design of converter stations. It is applicable to point-to-point and back-to-back HVDC systems based on line-commutated converter (LCC) technology. This document provides guidance and supporting information on the procedure for system design and the technical issues involved in the system design of HVDC transmission projects for both…
Fibre optic interconnecting devices and passive components - Connector optical interfaces - Part 3-1...
IEC 61755-3-1:2024 defines the dimensional limits of the optical interface that are necessary for single-mode fibre optic connectors with 2,5 mm or 1,25 mm diameter cylindrical zirconia (ZrO2) ferrules to meet the specific requirements for fibre-to-fibre interconnection, as defined in IEC 61755-2-1. Ferrules made from the material specified in this document are suitable for use in all the…
