IEC 63182的本部分规定了磁粉芯的尺寸。 本文件旨在包括在工业中广泛使用和引用的磁粉芯，因为它们被纳入国家标准，或者被认为在工业中有广泛的用途。在适用的情况下，每个粉芯的现有工业名称将与IEC 63182系列中的零件一起出现。 本文件还提供了磁粉芯表面不规则性允许极限的指南。它被认为是一种通用规范，有助于磁粉芯制造商和用户就表面不规则性进行对话。 购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 63182 specifies the dimensions of magnetic powder cores. 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. 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.All current amendments available at time of purchase are included with the purchase of this document.
