Magnetic materials - Part 8-6: Specifications for individual materials - Soft magnetic metallic materials
IEC 60404-8-6:2016 specifies the general requirements, magnetic properties, geometric characteristics and tolerances as well as inspection procedures for pure iron, silicon-iron, nickel-iron and cobalt-iron. The materials are in the form of bar, billet, sheet, strip or wire. The alloys covered correspond to those defined by classes A, C1, C2, E1 to E4 and F1 to F3 in IEC 60404-1. This edition includes the following significant technical changes with respect to the previous edition: Removal of Table 2b).
Magnetische Werkstoffe - Teil 8-6: Anforderungen an einzelne Werkstoffe – Weichmagnetische metallische Werkstoffe
Matériaux magnétiques - Partie 8-6: Spécifications pour matériaux particuliers - Matériaux métalliques magnétiquement doux
L’IEC 60404-8-6 :2016 spécifie les exigences générales, les propriétés magnétiques, les caractéristiques géométriques et leurs tolérances, ainsi que les modes de contrôle pour le fer pur, le fer-silicium, le fer-nickel et le fer-cobalt. Les matériaux se présentent sous forme de barres, billettes, tôles, bandes ou fils. Les alliages concernés correspondent à ceux définis par les classes A, C1, C2, E1 à E4 et F1 à F3 de l’IEC 60404-1. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: Suppression du Tableau 2b).
Magnetni materiali - 8-6. del: Specifikacije za posamezne materiale - Mehkomagnetni kovinski material (IEC 60404-8-6:2016)
Ta del standarda IEC 60404 določa splošne zahteve, magnetne lastnosti, geometrijske lastnosti in tolerance ter postopke pregledovanja za čisto železo, železo na osnovi silikona, železo na osnovi niklja in železo na osnovi kobalta. Materiali so v obliki drogov, palic, pločevin, trakov ali žice. Obravnavane zlitine ustrezajo tistim, ki so opredeljene z razredi A, C1, C2 ter od E1 do E4 in od F1 do F3 iz standarda IEC 60404-1.
Magnetni materiali, ki se uporabljajo predvsem za releje ter železne in jeklene izdelke, razvrščeni le po koercivnosti, so zajeti v standardu IEC 60404-8-10. Standard IEC 60404-8-10 je manj omejujoč v smislu magnetnih lastnosti kot železa (razred A) in jekla na osnovi silikona (razreda C21 in C22), določeni v tem standardu, vendar podaja obširnejša odstopanja glede mer.
Neorientirana in orientirana jekla na osnovi silikona (C21 in C22) za industrijsko uporabo omrežnih frekvenc, razvrščena po določeni skupni izgubi, so zajeta v standardih IEC 60404-8-3, IEC 60404-8-4 in IEC 60404-8-7.
Neorientirani in orientirani tanki magnetni materiali za uporabo pri srednjih frekvencah, razvrščeni po določeni skupni izgubi, so zajeti v standardu IEC 60404-8-8.
