IEC 60676:2024 This document specifies the basic test procedures, conditions and methods for establishing the main performance parameters and the main operational characteristics of furnaces for direct arc heating, forming arcs between the electrode and metal, such as electric arc furnaces using alternating current (EAF AC) or direct current (EAF DC), and ladle furnaces (LF), with rated power level above 500 kVA . This fourth edition cancels and replaces the third edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The structure has been redrafted according to IEC 60398:2015. b) The scope has been redrafted. c) The terms/definitions, normative references and bibliography have been updated and completed. d) The test methods and content from IEC 60398:2015 have been confirmed, replaced, or complemented with regards to direct arc furnaces (EAF, LF). e) The annexes from IEC 60398:2015 have been confirmed, replaced, or complemented with regards to direct arc furnaces (EAF, LF). L’IEC 60676:2024 specifie les procedures, les conditions et les methodes dessai fondamentales pour etablir les principaux parametres de performance et les principales caracteristiques de fonctionnement des fours qui utilisent le chauffage par arc direct, qui forme des arcs entre lelectrode et le metal, tels que les fours a arc electrique a courant alternatif (EAF AC, Electric Arc Furnace using Alternating Current) ou a courant continu (EAF DC, Electric Arc Furnace using Direct Current), et les fours poches (LF, Ladle Furnace), avec un niveau de puissance assignee superieur a 500 kVA. Cette quatrieme edition annule et remplace la troisieme edition parue en 2011. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) la structure a ete alignee sur lIEC 60398:2015; b) le domaine dapplication a ete repris; c) les termes et definitions, les references normatives et la bibliographie ont ete mis a jour et completes; d) les methodes dessai et le contenu de lIEC 60398:2015 ont ete confirmes, remplaces ou completes en ce qui concerne les fours a arc direct (FAE, LF); e) les annexes de lIEC 60398:2015 ont ete confirmees, remplacees ou completees en ce qui concerne les fours a arc direct (FAE, LF). La version francaise de la norme na pas ete soumise au vote.
