From September 12 to 13, the review meeting on the international standard proposal of SQ type ferrite magnetic core was held in our city. Cui Ying, chairman of the National Magnetic Components and Ferrite Materials Standardization Technical Committee, attended the meeting and delivered a speech. Some experts from the National Magnetic Standard Committee, members of the Standard Compilation Group of Shandong Chunguang Technology Group, University of Electronic Science and Technology of China and other standards attended the meeting. Meng Qinghui, a fourth-level researcher at the Municipal Market Supervision Administration, and Zhang Mingkun, member of the Party Working Committee of the High-tech Zone and deputy director of the Management Committee, attended the opening meeting.
The meeting mainly reviewed two international standards proposals, IEC63093-X, 'Ferritant Core-Dimensional and Surface Defect Limit Guide: SQ-type Magnetic Core' and IEC 60401-1, 'Soft Magnetic Core Terms and Definitions: Physical Defect Terms and Dimensional Annotations'. The above standards were led and participated in the formulation of Kaitong Electronics Company, a subsidiary of Chunguang Technology Group in our district. After this review meeting is passed, it will be submitted to the National Standards Committee for review and then submitted to the IEC. On February 28 this year, the National Magnetic Standards Commission held the drafting and launching meeting of the above standards in Linyi. After the meeting, the members of the preparation team carried out parameter calculation and verification and experimental verification according to the plan, and formed an international standard proposal to be submitted for review at this meeting.
SQ ferrite cores are important magnetic devices for anti-common mode interference inductors, and are widely used in high-end market fields such as new energy, energy storage, high-end equipment, and communications. As one of the basic standards for soft ferrite cores, this product-related standards play an important guiding role in production, trade and application. Chunguang Technology Group of our district and relevant domestic universities, research institutes and enterprises jointly participate in the standard formulation task, which is conducive to improving the competitiveness of my country's soft ferrite products in the international market and further enhancing my country's influence and voice in the field of international standardization of magnetic materials.
