标准摘要
[中文适用范围]： IEC 63182-7:2025 规定了对于由金属磁性粉末制成的优选范围的EER磁芯而言，对机械互换性至关重要的尺寸，以及与之配套使用的线圈模芯的基本尺寸，同时还规定了在涉及这些磁芯的计算中应使用的有效参数值，并给出了适用于EER磁芯的表面不规则度允许限值的指导原则。本文件是一项规范，有助于磁性粉末磁芯制造商与客户之间就表面不规则度问题进行协商。附录A中讨论了使用“派生”标准的情况，这些标准对组件部件提供了更详细的规范，同时仍允许符合本文件的要求。 [外文原描述]： IEC 63182-7:2025 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EER-cores made of metallic magnetic powder, the essential dimensions of coil formers to be used with them as well as the effective parameter values to be used in calculations involving them and gives guidelines on allowable limits of surface irregularities applicable to EER-cores. This document is a specification that is useful in the negotiations between magnetic powder core manufacturers and customers about surface irregularities. The use of “derived” standards which give more detailed specifications of component parts while still permitting conformance with this document is discussed in Annex A.
