Anotation

IEC 61631:2020 specifies a test method for the mechanical strength of cores made of magnetic oxides. This test method is suitable for most of the E-cores, ETD-cores, I-cores and ring-cores but other core types such as U-cores could be tested according to a derived method agreed by the parties concerned. This document is also applicable to the mechanical strength measurement of magnetic powder cores. This edition includes the following significant technical changes with respect to the previous edition: - the phrase: "This document is also applicable to the mechanical strength measurement of magnetic powder cores" has been added in the scope; - IEC 61246 has been replaced by IEC 63093-8; EN 1002-2 has been replaced by ISO 7500-1; ISO 4677-1 and ISO 4677-2 have been withdrawn; - dimensions D and F in Figure A.1 and Table A.1 have been changed to be consistent with Figure 1 of IEC 63093-8:2018; - addition of the content of ring-cores test; - addition of Annex B; - the location of the jig is amended in Figure 3; - in Figure 5, the roller bars are moved to the edge of the I-core, aligned with the core. IEC 61631:2020 specifie une methode dessai pour la resistance mecanique des noyaux en oxydes magnetiques. Cette methode dessai est adaptee a la plupart des noyaux E, noyaux ETD, noyaux I et noyaux toriques, mais dautres types de noyaux tels que les noyaux en U peuvent etre soumis aux essais selon une methode derivee convenue par les parties concernees. Le present document est egalement applicable au mesurage de la resistance mecanique des noyaux en poudre magnetique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: la phrase "Le present document est egalement applicable au mesurage de la resistance mecanique des noyaux en poudre magnetique" a ete ajoutee au domaine d’application; l’IEC 61246 a ete remplacee par l’IEC 63093-8; l’EN 1002-2 a ete remplacee par l’ISO 7500-1; l’ISO 4677-1 et l’ISO 4677-2 ont ete supprimees; les dimensions D et F dans la Figure A.1 et le Tableau A.1 ont ete modifiees pour se conformer a la Figure 1 de l’IEC 63093-8:2018; ajout du contenu de l’essai des noyaux toriques; ajout de l’Annexe B; l’emplacement du gabarit est modifie dans la Figure 3; dans la Figure 5, les barres de roulement sont deplacees au bord du noyau I, alignees avec le noyau.
