Science and Technology Daily, Lanzhou, August 14 (Reporter Jie Manbin) The reporter learned from the 510th Institute of the Fifth Academy of China Aerospace Science and Technology Corporation (hereinafter referred to as the 510th Institute) on the 14th that Academician Li Detian is in command, and the 510th Institute is in charge. Northeastern University, Lanzhou Arts and Sciences The first international standard in the field of vacuum testing and measurement in my country, "Specification, Calibration and Measurement Uncertainty of Magnetic Levitation Rotor Vacuum Gauges", jointly formulated by the college, Shenyang Institute of Vacuum Technology, Beijing Satellite Environmental Engineering Institute, China Institute of Metrology, etc. It was officially released and implemented on August 5, achieving a breakthrough in my country's "from 0 to 1" in terms of international standards in this field.

  It is understood that the international standard formulation process is roughly divided into 6 stages, namely the proposal stage, the preparatory work draft stage, the technical committee draft stage, the consultation draft stage, the approval stage and the printing and publishing stage.

It generally takes more than 36 months for an international standard to be approved as a standard from the time it is proposed.

  In June 2019, the International Organization for Standardization Vacuum Technical Committee (ISO/TC112) held its annual working meeting in Kyoto, Japan.

Based on the international influence of the 510 Institute and Academician Li Detian in the field of vacuum testing, China won the leading task of formulating the ISO 24477 international standard at this meeting.

After 3 years of careful organization and implementation, the Working Draft (WD) was submitted in October 2019 and the project was formally established. DIS), entering the approval stage (FDIS) in March 2022, and entering the final print distribution stage (ISO) in August 2022.

  During the formulation of this standard, dozens of experts and scholars from scientific research institutes of metrology technology institutions in China, Germany, Japan, the United States, and Switzerland participated in the exchange and discussion.

The team responded to the opinions and suggestions put forward by experts from various countries one by one and was unanimously recognized by the experts.

  The 510 Institute has 60 years of vacuum technology research and engineering application background, relying on national platforms such as the International Joint Research Center for Vacuum Metrology and Application Technology, the Key Laboratory of Vacuum Technology and Physics for National Defense Technology, and the National Defense Technology Industrial Vacuum First-class Metrology Station.

Leading the formulation of the first international standard in the field of vacuum testing and measurement in my country is a sign that the technical level of the 510 in this field has reached a world-class level, a symbol of the international voice in this field, and an important foundation for building a world-class vacuum enterprise.
