标准摘要
[中文适用范围]： IEC 60404 的这一部分规定了除电工钢和软铁氧体之外的软磁材料在 20 Hz 至 100 kHz 频率范围内的交流磁性能的测量方法。 IEC 60404 本部分涵盖的材料包括 IEC 60404-8-6 中列出的特种合金、非晶和纳米晶软磁材料、冲压和烧结以及金属注射成型零件（例如 IEC 60404-8-9 中列出的零件） 、铸造零件和软磁复合材料。本部分的目的是定义采用环法测量软磁材料磁性能的一般原理和技术细节。对于以粉末形式供应的材料，通过适合该材料的压制方法形成环形试样。软磁材料直流磁性能的测量按照IEC 60404-4的环法进行。软磁元件的磁特性测定是根据 IEC 62044-3 进行的。注：IEC 62044-3:2000 规定了频率范围高达 10 MHz 的软磁元件的交流磁特性的测量方法。通常，测量是在（23±5）℃的环境温度下对先磁化后退磁的试样进行的。经有关各方同意，可以在其他温度范围内进行测量。 [外文原描述]： IEC 60404-6:2018 specifies methods for the measurement of AC magnetic properties of soft magnetic materials, other than electrical steels and soft ferrites, in the frequency range 20 Hz to 100 kHz. The materials covered by this part of IEC 60404 include those speciality alloys listed in IEC 60404-8-6, amorphous and nano-crystalline soft magnetic materials, pressed and sintered and metal injection moulded parts such as are listed in IEC 60404-8-9, cast parts and magnetically soft composite materials. The object of this part is to define the general principles and the technical details of the measurement of the magnetic properties of magnetically soft materials by means of ring methods. For materials supplied in powder form, a ring test specimen is formed by the appropriate pressing method for that material. The measurement of the DC magnetic properties of soft magnetic materials is made in accordance with the ring method of IEC 60404-4. The determinations of the magnetic characteristics of magnetically soft components are made in accordance with IEC 62044-3. This edition includes the following significant technical changes with respect to the previous edition: a) adaption to modern measurement and evaluation methods, in particular the introduction of the widely spread digital sampling method for the acquisition and evaluation of the measured data; b) limitation of the frequency range up to 100 kHz; c) deletion of Clause 7 of the second edition that specified the measurement of magnetic properties using a digital impedance bridge; d) addition of a new Clause 7 on the measurement of the specific total loss by the wattmeter method, including an example of the application of the digital sampling method; e) addition of an informative annex on the technical details of the digital sampling technique for the determination of magnetic properties. The contents of the corrigendum of November 2018 have been included in this copy.
