BS EN 60404-6:2003 磁性材料.使用环形样品测量磁性软金属及粉末材料在20 Hz至200 kHz频率范围内磁特性的方法

This part of IEC 60404 specifies methods for the measurement of a.c. magnetic properties of materials in the frequency range 20 Hz to 200 kHz other than electrical steels and soft ferrites. The materials covered by this part of IEC 60404 include those speciality alloys listed in IEC 60404-8-6, amorphous and nanocrystalline 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. DC magnetic measurements on magnetically soft materials shall be made in accordance with the ring method of IEC 60404-4. The determinations of the magnetic characteristics of magnetically soft components shall be made in accordance with IEC 62044-3. Normally, the measurements shall be made at an ambient temperature of (23 ±5) ℃ on ring test specimens which have first been magnetized, then demagnetized. Measurements can be made over other temperature ranges by agreement between supplier and purchaser.

ASTM A893/A893M-03(2015) 微波频率下非金属磁性材料复合介电常数的标准试验方法

3.1 This test method can be used to evaluate batch type or continuous production of material for use in microwave applications. It may be used to determine the loss factors of microwave ferrites or help evaluate absorption materials for use in microwave ovens and other shielding applications. 3.2 The values obtained by use of this practice can be used as quality assurance information for process control, or both, when correlated to the chemistry or process for manufacturing the material. 1.1 This test method covers the measurement of the complex dielectric constant of isotropic ferrites for extremely high-frequency applications. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Within this standard, SI units are shown in brackets. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

General specification for metal magnetic power cores

BS EN 62044-1:2002 软磁材料制芯件.测量方法.总规范

This International standard applies to magnetic cores made of soft magnetic materials used in inductors, transformers and devices used to suppress electromagnetic interference. This standard is to provide guidance for the specification of measuring methods for both magnetic and non-magnetic (for example, mechanical, electrical, etc.) properties. This standard is limited to the general principles to be followed for the various possible test methods. For the magnetic properties, it should be considered that the measurement result using a measuring coil can be directly related to a specified parameter (for example inductance) of a magnetic component using the magnetic core. In this case, the measuring method should be chosen in order to obtain a good correlation with the corresponding magnetic component measurement results.
