IEC 60401-3:20 15给出了软磁铁氧体材料特性的统一呈现方法和测定这些特性的测量条件的指南。它旨在用于制造商的变压器和电感器铁芯目录中，以帮助此类数据的可比性。为用户和制造商提供了关于铁氧体磁芯和使用铁氧体磁芯的器件的可靠性测试和规范的附加指南。与上一版相比，此版本包括以下重大技术变更: -在第6条中增加可靠性。

IEC 60401-3:2015 gives guidelines for a uniform method of presentation for the properties of magnetically soft ferrite materials and measuring conditions under which they should be determined. It is intended for use in manufacturers' catalogues of transformer and inductor cores, in order to aid the comparability of such data. Additional guidance is given for users and manufacturers concerning testing and specification of reliability for ferrite cores and for devices using ferrite cores. This edition includes the following significant technical changes with respect to the previous edition:
- addition of reliability in Clause 6.
