IEC 60773:2021 applies to test methods for the measurement of the operational characteristics of brushes designed to operate on commutating and slip ring machines under specified test conditions. By extension some tests may be relevant for other kinds of sliding electrical contacts for electrical appliances. This second edition cancels and replaces the first edition published in 1983. This…

IEC 60773:2021 s'applique aux méthodes d'essai pour le mesurage des caractéristiques opérationnelles des balais conçus pour fonctionner sur des machines avec commutation et sur des machines à bagues, dans des conditions d'essai spécifiées. Par extension, certains essais peuvent être pertinents pour d’autres types de contacts électriques glissants pour appareils électriques. Cette…

IEC 60794-4-30:2021 specifies the optical fibre, cable elements, cable construction requirements, main requirements for installation and operating conditions, cable design characteristics and test for OPPC (optical phase conductor), used for carrying current as well as communication and data transmission. The corresponding environmental declaration can be built according to IEC TR 62839-1. The…

IEC 60794-4-30:2021 spécifie les fibres optiques, les éléments de câble, les exigences de construction des câbles, les principales exigences sur les conditions d'installation et de fonctionnement, les caractéristiques de conception des câbles et les essais sur les conducteurs de phase à fibres optiques (OPPC - optical phase conductor), utilisés pour transporter du courant, mais aussi pour…

IEC TS 60034-27-5:2021 provides an off-line measurement method of the partial discharge inception and extinction voltage on winding insulation under repetitive impulse voltage. This document is relevant to rotating machines supplied by a voltage source converter.

IEC TR 63042-303:2021(E) specifies measurement methods of UHV AC transmission line power frequency parameters. These measured parameters mainly include sequence parameters, mutual parameters between double-circuit lines, phase parameters and some other related parameters.

IEC PAS 61162-103:2021 supports the transfer of data between various equipment. This document specifies more equipment Talker IDs, amends existing sentences and introduce new sentences to facilitate more functionality between equipment.

IEC 63229:2021(E) gives guidelines for the definition and classification of defects in GaN epitaxial film grown on SiC substrate. They are identified and described on the basis of examples, mainly by schematic illustrations, optical microscope images, and transmission electron microscope images for these defects. This document covers only defects in as-grown GaN epitaxial film on SiC substrate…

IEC 62899-402-3:2021(E) specifies the optical measurement method for acquiring two-dimensional images of voids and obtaining the void-related attributes in the dried or cured printed patterns which are part of the electronic products in the field of printed electronics. The measurable voids using this document are limited to those that are distinguishable by the optical image measurement. NOTE …

IEC 60809:2021 is applicable to electric light sources for use in automotive applications, for example in road illumination devices and/or light signalling devices for road vehicles. It is especially applicable to light sources listed in UN Resolution R.E.5 and light sources subject to other legislations. This fourth edition cancels and replaces the third edition published in 2014, Amendment 1:…
