标准范围

IEC？60404-7:20 19规定了开路磁性材料矫顽力的测量方法。？本文件适用于矫顽力从0,2？A/m到160？kA/m。与上一版相比，此版本包括以下重大技术变更:条款1:范围包括适用于本标准的磁性材料的更详细描述；条款4:图2-简化了方法A和B的电路图，并添加了螺线管内部的磁通门探头；第7条:增加了对地球磁场以及静态和动态磁噪声场的补偿；条款8:增加了测量区域的磁屏蔽；9.2.2:测试样本中通量的局部和整体测量的测量方法已经分开，并且已经考虑了测试样本的尺寸和形状的限制。9:3:使用VSM（振动样品磁力计）的方法C已从9.3移至附录B。术语“复杂形状的试样”在几个条款中已被“不同于椭球体的试样”取代。附件A的性质已从"资料性"改为"规范性"。

IEC？60404-7:2019 specifies a method of measurement of the coercivity of magnetic materials in an open magnetic circuit.？This document is applicable to all magnetic materials with coercivities from 0,2？A/m to 160？kA/m.
This edition includes the following significant technical changes with respect to the previous edition:

1. Clause 1: The scope includes a more detailed description of the magnetic materials which applies to this standard;
2. Clause 4: Figure 2 – circuit diagram for methods A and B was simplified and the fluxgate probes inside the solenoid have been added;
3. Clause 7: Compensation for the earth’s magnetic field and for static and dynamic magnetic noise fields has been added;
4. Clause 8: Magnetic shielding of the measuring region has been added;
5. 9.2.2: The measuring methods for local and integral measurement of the flux in the test specimen have been separated and the limitations in size and shape of the test specimen have been considered.
6. 9:3: The method C with a VSM (Vibrating Sample Magnetometer) has been moved from 9.3 to the Annex B.
7. The term "complex shaped test specimen" has been replaced in several clauses by "test specimen different from ellipsoids".
8. The character of Annex A has been changed from “informative” to “normative”.
