GSO IEC 60404-1:2015 磁性材料 第1部分：分类

This standard is intended to classify commercially available magnetic materials. The term "magnetic materials" denotes substances where the application requires the existence of ferromagnetic or ferrimagnetic properties. In this standard, the classification of magnetic materials is based upon the generally recognized existence of two main groups of products: soft magnetic materials (coercivity ≤1 000 A/m); hard magnetic materials (coercivity >1 000 A/m). Within these main groups, the classification when appropriate recognizes the following characteristics: the main alloying element and the metallurgical state and physical properties of the material; when possible and convenient, the relationship between these characteristics is identified. A classification by specific areas of application cannot be applied to all materials because different materials can very often be used for the same application depending on the characteristics required.

GSO IEC 60404-1-1:2015 磁性材料 第1-1部分：分类 电工钢板、带材和叠片的表面绝缘

This part of IEC 60404 establishes a classification of surface insulations for electrical steel sheet, strip and laminations according to their general composition, relative insulating ability and function. These surface insulations are either oxide layers or applied coatings. The purpose of this classification is to create a nomenclature for the various types of surface insulations and to assist users of surface insulations by providing general information about the chemical nature and use of the surface insulations. It is not the intent of this classification to specify insulation requirements in terms of specific values of surface insulation resistance. Such requirements are agreed between the purchaser and the steel producer, where applicable. The classification is used in conjunction with the various specifications for cold rolled electrical steels (see the standards in the IEC 60404-8 series in Clause 2).

GSO IEC 62044-3:2014 软磁材料磁芯 测量方法 第3部分：高励磁水平下的磁性能

This standard provides measuring methods for power loss and amplitude permeability of magnetic cores forming the closed magnetic circuits intended for use at high excitation levels in inductors, chokes, transformers and similar devices for power electronics applications. The methods given in this standard can cover the measurement of magnetic properties for frequencies ranging practically from d.c. to 10 MHz, and even possibly higher, for the calorimetric and reflection methods. The applicability of the individual methods to specific frequency ranges is dependent on the level of accuracy that is to be obtained. The methods in this standard are basically the most suitable for sine-wave excitations. Other periodic waveforms can also be used; however, adequate accuracy can only be obtained if the measuring circuitry and instruments used are able to handle and process the amplitudes and phases of the signals involved within the frequency spectrum corresponding to the given induction and field strength waveforms with only slightly degraded accuracy. NOTE It may be necessary for some magnetically soft metallic materials to follow specific general principles, customary for these materials, related to the preparation of specimens and prescribed calculations. These principles are formulated in IEC 60404-8-6.

GSO IEC 61333:2014 标记U形和E形心形

This International Standard specifies marking locations and a coding system of marking, especially for U and E shape ferrite cores. An alphanumerical marking printed or attached to cores reduces the risk of incorrect assembly, mixing of materials and/or mixing of gapped cores on an assembly line. The markings of the AL value or of the gap length are especially important to avoid this kind of problem and the coding system is specified in this standard.

GSO IEC 61609:2014 微波铁氧体元件 技术规格准备指南

This International Standard gives guidance for uniform rules for the drafting of specifications for microwave ferrite components. Microwave ferrite components in this guide are restricted to transmission line components such as circulator, isolator, phase-shifter, switch and filter. Less common components such as attenuators and limiters are not specifically described, but many of the properties considered may apply to them.

This range specifically covers cores designed for use in power transformers, for example for switched mode power supplies operating typically at 25 kHz switching frequency; it lists preferred dimensions of these cores together with their tolerances as far as these are of importance for mechanical and electrical interchangeability.

ASTM A773/A773M-14 使用磁滞曲线记录仪测定低矫顽磁性材料的直流磁性能的标准试验方法

5.1 Hysteresigraphs permit more rapid and efficient collection of normal induction and dc hysteresis (B-H loop) data as compared to the point by point ballistic Test Methods A341/A341M and A596/A596M. The high measurement point density offered by computer-automated systems is often required for computer aided design of electrical components such as transformers, motors, and relays. 5.2 Hysteresigraphs are particularly desirable for testing of semihard and hard magnetic materials, where either the entire second quadrant (demagnetization curve) or entire hysteresis loop is of primary concern. Test Method A977/A977M describes the special requirements for accurate measurement of hard (permanent magnet) materials. 5.3 Hysteresigraphs are not recommended for measurement of initial permeability of materials with high magnetic permeability such as nickel-iron, amorphous, and nanocrystalline materials due to errors associated with integrator drift; in these cases, Test Method A596/A596M is a more appropriate method. 5.4 Provided the test specimen is representative of the bulk sample or lot, this test method is well suited for design, specification acceptance, service evaluation, and research and development. 1.1 This test method provides dc hysteresigraph procedures (B-H loop methods) for the determination of basic magnetic properties of materials in the form of ring, spirally wound toroidal, link, double-lapped Epstein cores, or other standard shapes that may be cut, stamped, machined, or ground from cast, compacted, sintered, forged, or rolled materials. It includes tests for normal induction and hysteresis loop determination taken under conditions of continuous sweep magnetization. Rate of sweep may be varied, either manually or automatically at different portions of the curves during measurement. 1.2 The equipment and procedures described in this test method are most suited for soft and semi-hard materials with intrinsic coercivity less than about 100 Oersteds [8 kA/M]. Materials with higher intrinsic coercivities should be tested according to Test Method A977/A977M. 1.3 The values and equations stated in customary (cgs-emu and inch-pound) or SI units are to be regarded separately as standard. Within this standard, SI units are shown in brackets. 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 nonconformance with this standard. 1.4 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.

GSO IEC 60404-15:2013 磁性材料 第 (15) 部分：薄磁性材料相对磁导率的测定方法

IEC 60404-15:2012 specifies a solenoid method, a magnetic moment method, a magnetic balance method and a permeability meter method for the determination of the relative magnetic permeability of feebly magnetic materials (including austenitic stainless steel). The magnetic balance and permeability meter methods are both comparison methods calibrated using reference materials to determine the value of the relative magnetic permeability of the test specimen.
