Ferrite cores - Guidelines on dimensions and the limits of surface irregularities - Part 10: PM-cores and associated parts
IEC 63093-10:2022 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of PM-cores made of magnetic oxides, the main dimensions for coil formers to be used with these cores and the locations of their pins on a modular printed wiring grid in relation to the base outlines of cores. It also specifies the effective parameter values to be used in calculations and gives guidelines on allowable limits of surface irregularities applicable to the PM-cores.

L'IEC 63093-10:2022 spécifie les dimensions qui jouent un rôle majeur dans l'interchangeabilité mécanique d'une gamme préférentielle de noyaux PM constitués d'oxydes magnétiques, les dimensions principales des supports de bobine à utiliser avec ces noyaux et les emplacements de leurs broches sur une grille d'un circuit imprimé modulaire par rapport aux encombrements de base des noyaux. Elle spécifie également les valeurs des paramètres effectifs à utiliser dans les calculs et les lignes directrices relatives aux limites admissibles pour les irrégularités de surface applicables aux noyaux PM.
Feritna jedra - Smernice o merah in mejnih vrednostih površinskih nepravilnosti - 10. del: PM-jedra in pripadajoči deli
Standard IEC 63093-10:2022 določa mere, ki so pomembne za mehansko medsebojno zamenljivost prednostnega razpona feritnih Pm-jeder iz magnetnih oksidov, bistvene mere tuljave, ki se uporablja s temi jedri, ter položaje njihovih priključkov na modularni mreži tiskanega vezja glede na osnovno sestavo jeder. Določa tudi vrednosti efektivnih parametrov, ki se uporabljajo pri izračunih, in podaja smernice glede omejitev površinskih nepravilnosti, ki veljajo za PM-jedra.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications
