IEC 63093-1:20 20规定了铁氧体磁芯表面不规则性的尺寸和允许限值。 本文件旨在排除铁氧体磁芯，铁氧体磁芯是用途有限的专用磁芯。此外，也排除了仅与标准芯略有不同的特殊芯。 IEC发布了铁氧体磁芯系列的电气标准，以及铁氧体磁芯系列的这一系列尺寸标准。对一种类型标准中列出的铁氧体磁芯的修改反映在另一种类型中。 本文件被认为是在铁氧体磁芯供应商和用户之间关于表面不规则性的对话中有用的通用规范。 本第一版取消并取代了2015年发布的IEC 60424-1第二版和IEC 62317第一版-1发表于2007年。本版构成技术修订版。 与IEC 60424-1和IEC 62317-1之前版本相比，本版本包括以下重大技术变更: a)本文件集成了IEC 60424-1和IEC 62317-1。

IEC 63093-1:2020 specifies the dimensions and allowable limits of surface irregularities of ferrite cores.
It is intended that this document excludes ferrite cores which are specialty cores with limited use. Also, special cores which are only marginal variations upon standard cores are excluded.
IEC publishes electrical standards for families of ferrite cores, as well as this series of dimensional standards for families of ferrite cores. Modifications to the ferrite cores listed in one type of standard are reflected in the other type.
This document is considered as a general specification useful in the dialogue between ferrite core suppliers and users about surface irregularities.
This first edition cancels and replaces the second edition of IEC 60424-1 published in 2015 and the first edition of IEC 62317-1 published in 2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous editions of IEC 60424-1 and IEC 62317-1:
a) this document integrates IEC 60424-1 and IEC 62317-1.
