    As the leading enterprise insoft magnetic material industry of China, TDG Holding Co., Ltd. (hereinafter referred to as TDG) upholds the route of transforming technical achievements into standards.Last August, two international standards, developed and amended under the guidance of the Company, were issued and implemented. The IEC 60424-8 Ferrite cores - Guidelines on the limits of surface irregularities - Part8: PQ-cores is the first international standard in thisfield prepared under the leadership of China and theIEC62317–13 Ferrite cores-Dimensions - Part 13: PQ-cores for use in power supply applications is a revision of the 2008 version. Considering the application ofPQ-cores in such new fields as electric vehicles and solar energy, TDG especially added the definition of gas hole andallowable surface defect of the gas hole and crystal spot in drafting new standard this time. IEC/TC51 (Magnetic Components and Ferrite Materials Technical Committee of International Electrotechnical Commission) has agreed to add the indicator of "gas holedefect " in the60424 series standards.





    The Company established a full-time institute for standardization work - Information and Standardization Institute in the provincial enterprise research institute. The Company invests not less than RMB 1 million yuan in standardization work each year, and has trained a talent team with technical background and accomplishment in standardization work. In 2010, Zhang Ruibiao, the leader in magnetic material industry, and professor-level senior engineer of the Company won the IEC1906 award. This is the highest reward to the standardization experts with outstanding contributions in the world by International Electrotechnical Commission.




    Moreover, before the issuance of two international standards mentioned above, TDG had taken the lead to draft 2 national standards and 4 industrial standards. At present, TDG is researching and developing 2 international standards and 7 national standards.
