Ferrite cores - Guidelines on the limits of surface irregularities - Part 2: RM-cores

IEC 60424-2:2015 provides guidelines on the allowable limits of surface irregularities applicable to RM-cores in accordance with the relevant generic specification. This standard should be considered as a sectional specification useful in the negotiations between ferrite core manufacturers and customers about surface irregularities. Normative reference. This edition includes the following significant technical changes with respect to the previous edition: - addition of crystallites in 3.6 and of pores in 3.7.

Ferritkerne - Leitfaden für Grenzwerte von sichtbaren Beschädigungen der Kernoberfläche - Teil 2: RM-Kerne

Noyaux ferrites - Lignes directrices relatives aux limites des irrégularités de surface - Partie 2: Noyaux RM

L'IEC 60424-2:2015 fournit des lignes directrices sur les limites admissibles des irrégularités de surface applicables aux noyaux RM conformément à la spécification générique applicable. Il convient de considérer la présente norme comme une spécification intermédiaire utile dans les négociations entre les fabricants de noyaux en ferrite et leurs clients sur les irrégularités de surface. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - ajout de cristallites en 3.6 et de pores en 3.7.

Feritna jedra - Smernice o mejnih vrednostih površinskih nepravilnosti - 2. del: RM-jedra

Ta del standarda IEC 60424 podaja smernice o dovoljenih mejnih vrednostih površinskih nepravilnosti, ki se uporabljajo za RM-jedra v skladu z ustrezno splošno specifikacijo. Ta standard naj bi se obravnaval kot področna specifikacija, uporabna za sklepanje dogovorov glede površinskih nepravilnosti med proizvajalci feritnih jeder in strankami. Zveza z drugim standardom.
