L’IEC 62228-5:2021 spécifie les méthodes d’essai et de mesure pour l’évaluation de la compatibilité électromagnétique (CEM) des circuits intégrés (CI) émetteurs‑récepteurs Ethernet placés en réseau. Elle définit les configurations d’essai, les conditions d’essai, les signaux d’essai, les critères de défaillance, les procédures d’essai, les montages d’essai et les cartes d’essai. Elle s’applique à…

IEC 62488-3:2021 applies to power line carrier terminals and networks used to transmit information over power networks including extra high, high and medium voltage (EHV/HV/MV) power lines using both digital and optionally analogue modulation systems in a frequency range between 16 kHz and 1 MHz (see also IEC 62488-1). In many countries, power line carrier (PLC) channels represent a significant…

IEC 62488-3:2021 s’applique aux équipements terminaux et aux réseaux à courants porteurs sur lignes d’énergie utilisés pour transmettre des informations sur les réseaux électriques, ce qui englobe les lignes d’énergie extra haute, haute et moyenne tension (EHT/HT/MT) qui utilisent les systèmes de modulation numériques et, éventuellement, analogiques dans une plage de fréquences comprise entre 16…

This document contains information on the design and operational practices for launch vehicle orbital stages for mitigating space debris. This document provides information to engineers on the requirements and recommendations in the space debris mitigation standards to reduce the growth of space debris by ensuring that launch vehicle orbital stages are designed, operated, and disposed of in a…

IEC 60947-9-2:2021 covers internal arc-fault control devices, hereinafter referred to as IACD, which are intended to: – detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by processing (at a minimum) the optical effect of an internal arc-fault, and – operate mitigation device (either external or combined) in order to minimize the effects of the internal arc-fault.

L'IEC 60947-9-2:2021 s’applique aux dispositifs de contrôle de défaut d’arc interne, ci-après désignés IACD, qui sont destinés à: – détecter les défauts d’arc interne dans les ensembles d’appareillage à basse tension, en traitant (a minima) le phénomène optique d’un défaut d’arc interne, et – faire fonctionner un dispositif de limitation (externe ou combiné) afin de réduire le plus…

This document specifies requirements for two types of reinforced hoses and hose assemblies of nominal size from 3,2 to 25, dependent on relation of minimum burst pressure to maximum working pressure. Each type is divided into classes dependent on maximum working pressure. They are suitable for use with: —    oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures…

This document specifies a determination procedure of energy resolution in the scanning transmission electron microscope or the transmission electron microscope equipped with the electron energy loss (EEL) spectrometer. This document is applicable to both in-column type EEL spectrometer and post-column type EEL spectrometer. These EEL signal detecting systems are applicable to a parallel detecting…

IEC 60974-8:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60974-8:2021 specifies safety and performance requirements for gas consoles intended to be used with combustible…

IEC 60974-8:2021 specifies safety and performance requirements for gas consoles intended to be used with combustible gases or oxygen. These gas consoles are designed to supply gases for use in arc welding, plasma cutting, gouging and allied processes in non-explosive atmospheres. The gas console can be external or internal to the power source enclosure. In the latter case, the power source shall…
