IEC 63093-10:2022规定了对磁性氧化物制成的首选永磁磁芯范围的机械互换性至关重要的尺寸，与这些磁芯一起使用的线圈成型器的主要尺寸，以及它们的引脚在模块化印刷布线网格上相对于磁芯基部轮廓的位置。它还规定了计算中使用的有效参数值，并给出了适用于粉末冶金芯的表面不规则性允许极限的指南。

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.
