The first proposal for international standards for magnetic flux leakage detection proposed by my country was successfully approved and received support from many countries including Italy, Brazil, Argentina and South Korea.
The successful establishment of China's first international standard for magnetic flux leakage testing marks the widespread international recognition of China's technological strength and development level in the field of non-destructive testing. The following is detailed information about the event:
Background of successful project proposal
In June 2023, Professor Shen Gongtian, Vice President of the China Special Equipment Testing and Research Institute, Chairman of the National Non Destructive Testing Standards Committee, and Chair of the Acoustic Emission Testing Subcommittee of the International Organization for Standardization's Non Destructive Testing Technical Committee (ISO/TC 135/SC9), served as the project leader 1 and initiated the approval vote for the proposal of the international standard for magnetic flux leakage testing. This proposal is based on the technical achievements of a national level scientific research project led by the China Special Equipment Testing and Research Institute, combined with domestic standards such as JB/T 10765-2023 "Non destructive Testing - Magnetic Leakage Testing Method for Atmospheric Pressure Metal Storage Tanks", NB/T 47013.12-2015 "Non destructive Testing of Pressure Equipment - Part 12: Magnetic Leakage Testing", and GB/T 31212-2014 "General Principles for Non destructive Testing - Magnetic Leakage Testing", and jointly proposed an international standard draft with units such as Ederson (Xiamen) Electronics Co., Ltd. and Shanghai Institute of Materials Research Co., Ltd.Background of successful project proposal

International support and cooperation
The proposal received support from multiple countries, including 9 national groups such as Italy, Brazil, Argentina, and South Korea, who voted in favor of it. At the same time, experts from Canada, Germany, Russia, Japan, and China actively participated in the development of the project. This is the 9th ISO standard developed under the leadership of Professor Shen Gongtian's team, and it is also another major breakthrough made by China in the field of international standards for non-destructive testing, following eddy current testing, thermal imaging testing, acoustic emission testing, and ultrasonic testing.
Standard content and significance
In the international standard system for non-destructive testing, ISO/AWI 22500 is the first international standard established for magnetic flux leakage testing. The successful establishment of this project means that China's magnetic flux leakage detection technology achievements have not only been applied and developed domestically, but also widely recognized internationally. It reflects that the development of China's magnetic flux leakage detection technology has entered the international advanced level, promoting the coordinated development and technological exchange of related industries at home and abroad. In addition, this standard will serve as a link and driving force for key technical standards in industrial and technological collaboration, further expanding the international influence of China's non-destructive testing and having significant implications for enhancing China's position in the global manufacturing industry.
Industry impact
With the acceleration of China's economic structural transformation and upgrading, non-destructive testing, as one of the important means to ensure the quality of industrial products, is becoming increasingly important. The successful establishment of this international standard not only highly affirms China's level of non-destructive testing technology, but also provides a unified standard framework for promoting advanced magnetic flux leakage testing technology worldwide. This will help improve the safety management level of various countries in industries such as energy, chemical, aerospace, etc., reduce the risk of safety accidents caused by material defects, and promote the healthy development of the global economy.
In summary, the successful establishment of China's first international standard for magnetic flux leakage testing is an important milestone in the field of non-destructive testing in China, which has a profound impact on promoting technological progress and exchange and cooperation in related industries at home and abroad.
