IEC 62496-2-214:2020 définit les dimensions d’interface normalisées pour la terminaison d'un ensemble de cartes à circuits optiques (OCB: optical circuit board) à guides d'ondes (désigné plus simplement sous le terme "ensemble") qui utilise des connecteurs de trente-deux canaux sur une seule rangée pour des guides d’ondes en polymère connectés par un connecteur PMT symétrique.

IEC 61643-12:2020 describes the principles for the selection, operation, location and coordination of SPDs to be connected to 50/60 Hz AC power circuits, and equipment rated up to 1 000 V RMS. These devices contain at least one non-linear component and are intended to limit surge voltages and divert surge currents. NOTE 1 Additional requirements for special applications are also applicable, If…

IEC 61643-12:2020 décrit les principes relatifs au choix, au fonctionnement, à l'emplacement et à la coordination des parafoudres à connecter à des circuits de puissance 50 Hz/60 Hz en courant alternatif, et des matériels de puissance allant jusqu'à 1 000 V en valeur efficace. Ces dispositifs contiennent au moins un composant non linéaire et visent à limiter les tensions de choc et à…

1 Scope This clause of Part 1 is replaced by the following. This part of IEC 60335 deals with the safety of electric fishing machines by means of which water may be electrified for the purpose of catching fish or for providing barriers to all animals living in water. The rated voltage of electric fishing machines is not more than 250 V for single phase machines and 480 V for other…

1 Domaine d’application 1.1 Cette norme s’applique à la conception, à l’installation, au fonctionnement, à l’entretien et à l’essai des génératrices de secours et des appareils connexes dont le rôle est d’assurer l’alimentation électrique de secours des charges : a) dans des bâtiments ou des installations en cas de panne de l’alimentation normale, lorsqu’une alimentation électrique de secours…

This document specifies stainless steel commonly used in manufacturing dental instruments. It is applicable to stainless steel materials used to manufacture either an entire instrument or a part of the instrument. It is applicable to single-use and reusable dental instruments, whether it is or it is not connected to a power-driven system. This document is not applicable to devices and instruments…

This document specifies the application module for AP242 managed model based 3D engineering. The following are within the scope of this document: products of automotive, aerospace and other mechanical manufacturers and of their suppliers, including parts, assemblies of parts, tools,…

IEC TR 60919-2:2008+A1:2015+A2:2020 provides guidance on the transient performance and fault protection requirements of high voltage direct current (HVDC) systems. It concerns the transient performance related to faults and switching for two-terminal HVDC systems utilizing 12-pulse converter units comprised of three-phase bridge (double way) connections but it does not cover multi-terminal HVDC…
