IEC 63182-1:20 2(E)规定了磁粉芯的尺寸。该文件还给出了磁粉芯表面不规则性允许限值的指南。它被认为是在磁粉芯制造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。 本文件旨在包括在工业中广泛使用和参考的磁粉芯，因为它们被包括在国家标准中，或者因为它们被认为在工业中具有广泛的用途。在适用的情况下，每个粉芯的现有工业名称应与IEC 63182系列中的零件一起出现。

IEC 63182-1:202 (E) specifies the dimensions of magnetic powder cores. This document also gives guidelines on the allowable limits of surface irregularities of magnetic powder cores. It is considered as a general specification useful in the dialogue between magnetic powder core manufacturers and users about surface irregularities.
It is intended that this document will include magnetic powder cores which are widely used and referenced in industry, either because they are included in national standards, or because they are seen to have broad-based use in industry. Where applicable, it is intended that the existing industrial name for each powder core will appear with the part within the IEC 63182 series.
