b) Changed the range of nickel content in E1 and E3 materials (see 4:5:1, 4:5:3, 2:5:1, 2:5:3 of the:2007 edition); c) Changed the range of cobalt content in F3 materials (see 4:6:3, 2:6:3 of the:2007 edition); d) Added category U5 - bonded rare earth iron nitrogen materials (see 5:5:6): This document is modified to adopt IEC 60404-1:2016 "Magnetic Materials Part 1: Classification": Compared with IEC 60404-1:2016, this document has made the following structural adjustments: ---Delete the section number 4:4:2:1, merge the title into 4:2:2, and subsequently adjust 4:4:2:1:1~4:4:2:1:6 to 4:4:2:1~4:4:2:6: Compared with IEC 60404-1:2016, this document has many technical differences: A list of these technical differences and their causes is shown in Appendix A: The following editorial changes have been made to this document: ---In order to coordinate with my country's standards, the name of the standard was changed to "Classification of Magnetic Materials";

---This is the first revision: Magnetic material classification1 ScopeThis document is suitable for classifying commercially available magnetic materials: The term "magnetic material" refers to applications requiring ferromagnetic or ferrimagnetic properties substance: In this document, the classification of magnetic materials is based on the two main recognized product categories: ---Soft magnetic materials (coercive force ≤ 1000A/m); ---Permanent (hard) magnetic materials (coercivity >1000A/m): Within these main categories, when properly classified, the following characteristics can be discerned: ---The main alloying elements, metallurgical state and physical properties of the material; --- Where possible and convenient, the interrelationships between these characteristics can also be identified: Classification according to specific application areas cannot be applied to all materials, since different materials can often be used in the same application, depending on the properties required by the application: the use of:2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document;
