IEC 61747-3:2015(E) applies to liquid crystal cells of the segment type monochrome. It gives details of the quality assessment procedures, inspection requirements, screening sequences, sampling requirements and test and measurement procedures required for the assessment of liquid crystal display cells. Instead of the qualification approval procedure, the capability approval procedure can be…

IEC 61747-3-1:2015(E) serves as a blank detail specification (BDS) for the IEC quality assessment system and contains requirements for style and layout and minimum content of the detail specifications. These requirements are applicable when the detail specification is published (e.g. for a standard product). This edition includes the following significant technical changes with respect to the…

IEC 60335-2-81:2015 deals with the safety of electric foot warmers and heating mats for household and similar purposes, their rated voltage being not more than 250 V. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this…

L'IEC 60335-2-81:2015 traite de la sécurité des chancelières et des carpettes chauffantes électriques destinées à un usage domestique ou analogue, dont la tension assignée n'est pas supérieure à 250 V. Les appareils non destinés à un usage domestique normal mais qui néanmoins peuvent constituer une source de danger pour le public, tels que les appareils destinés à être utilisés par des…

IEC 60398:2015 specifies the basic test procedures, conditions and methods for establishing the main performance parameters and the main operational characteristics of industrial installations and equipment intended for electroheating (EH) or electromagnetic processing of materials (EPM). This third edition cancels and replaces the second edition of IEC 60398 published in 1999 and the first…

L'IEC 60398:2015 spécifie les procédures, conditions et méthodes d'essai fondamentales permettant d'établir les paramètres de performance principaux, ainsi que les caractéristiques de fonctionnement principales des installations et équipements industriels de traitement électrothermique (EH) ou de traitement électromagnétique des matériaux (EPM). Cette troisième édition annule et…

IEC TS 62600-201:2015(E) establishes a system for analysing and reporting, through estimation or direct measurement, the theoretical tidal current energy resource in oceanic areas including estuaries (to the limit of tidal influence) that may be suitable for the installation of arrays of Tidal Energy Converters (TECs). It is intended to be applied at various stages of project lifecycle to provide…

IEC 62811:2015 specifies performance requirements for electronic controlgear for use on a.c. and/or d.c. supplies up to 1 000 V and/or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with discharge lamps, as specified in IEC 61167, which have information for low frequency square wave operation, where the frequency range of the low frequency is from 70 Hz to 400 Hz.

L'IEC 62811:2015 spécifie les exigences de performance des appareillages électroniques destinés à être utilisés sur des alimentations en courant alternatif et/ou en courant continu allant jusqu'à 1000 V et/ou sur des alimentations en courant alternatif jusqu'à 1 000 V à 50 Hz ou 60 Hz, associés avec des lampes à décharge, comme spécifié dans l'IEC 61167, comportant des…

IEC 60287-2-1:2015 is solely applicable to the conditions of steady-state operation of cables at all alternating voltages, and direct voltages up to 5 kV, buried directly in the ground, in ducts, in troughs or in steel pipes, both with and without partial drying-out of the soil, as well as cables in air. The term "steady state" is intended to mean a continuous constant current (100 %…
