标准范围

IEC？63093-7:20 18（E）规定了对由铁氧体制成的EER磁芯的优选范围的机械互换性很重要的尺寸、与它们一起使用的线圈形成器的基本尺寸以及在涉及它们的计算中使用的有效参数值，并给出了适用于EER磁芯的表面不规则性允许限值的指南。本文件是铁氧体磁芯制造商和客户之间关于表面不规则性的谈判中有用的规范。附录A中讨论了“衍生”标准的使用，这些标准给出了零部件的更详细的规格，同时仍然允许符合本文件。这个第一版取消并取代了IEC的第一版？62317-7发表于2005年。本版构成技术修订版。此版本包括以下与IEC相关的重大技术变化？62317-7:A）？IEC？63093-7整合IEC？62317-7和IEC？60424-3;b）？IEC？60424-3:20 15，表2，已作为表C.1纳入附录C。

IEC？63093-7:2018(E) specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of EER-cores made of ferrite, the essential dimensions of coil formers to be used with them as well 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 useful in the negotiations between ferrite core manufacturers and customers 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.
This first edition cancels and replaces the first edition of IEC？62317-7 published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC？62317-7:
a)？IEC？63093-7 integrates IEC？62317-7 and IEC？60424-3;
b)？IEC？60424-3:2015, Table 2, has been included in Annex C as Table C.1.
