IEC 63182的本部分规定了对机械互换性具有重要意义的尺寸的首选范围，并给出了金属磁粉制成的圆柱磁芯表面不规则性允许极限的指南。 本文件是磁粉芯供应商和用户就表面不规则性进行谈判时有用的规范。 附录A中讨论了“衍生”标准的使用，这些标准提供了更详细的零部件规范，同时仍允许遵守本文件。

This part of IEC 63182 specifies the preferred range of the dimensions that are of importance for mechanical interchangeability and gives the guidelines on allowable limits of surface irregularities for cylinder-cores made of metallic magnetic powder. This document is a specification useful in the negotiations between magnetic powder core suppliers and users about surface irregularities. The use of "derived" standards which give more detailed specifications of component parts while still permitting compliance with this document is discussed in Annex A.
