Establishes a classification of surface insulations for electrical steel sheet, strip and laminations according to their general composition, relative insulating ability and function. These surface insulations are either oxide layers or applied coatings. The purpose of this classification is to create a nomenclature for the various types of surface insulations and to assist users of surface insulations by providing general information about the chemical nature and use of the surface insulations. It is not the intent of this classification to specify insulation requirements in terms of specific values of surface insulation resistance. Such requirements are agreed between the purchaser and the steel producer, where applicable. The classification is used in conjunction with the various specifications for cold rolled electrical steels (see the standards in the IEC 60404-8 series in Clause 2). Etablit une classification des isolations de surface des toles, bandes et lamelles magnetiques en acier en fonction de leur composition generale, leur aptitude relative a lisolement et leur fonction. Ces isolations de surface sont soit des couches doxyde soit des revetements appliques. Lobjectif de cette classification est de creer une nomenclature pour les differents types disolations de surface et daider les utilisateurs disolations de surface en fournissant des informations generales sur la nature chimique et lutilisation des isolations de surface. Lintention de cette classification nest pas de specifier des exigences relatives a lisolation en termes de valeurs specifiques de resistance disolement superficiel. De telles exigences sont convenues entre lacheteur et le producteur dacier, le cas echeant. La classification est utilisee conjointement avec les diverses specifications pour les aciers magnetiques lamines a froid (voir les normes de la serie CEI 60404-8 dans lArticle 2).
