The National Metrology benchmark technology level represents the source of the national measurement value and embodies the highest measurement capability, which is one of the important signs of the national core competitiveness.
AQSIQ "national heavy instrument" 35 National Metrology benchmarks approved
In November 29th, at a press conference held in Beijing, the State Quality Inspection Bureau was informed that after comprehensive review according to law, there were 177 effective legal national measurement benchmarks in China, including 35 National Metrology benchmarks which were newly approved by technical transformation and upgrading. According to the international metrological comparison, 12 of them are in the leading international level, and 115 have reached the international advanced level.
According to Xie Jun, director of the Metrology Department of the State Quality Inspection Administration, the General Administration of quality inspection and inspection has closely organized the national metrological technical force, aggregated measurement resources in the near future, and carried out a comprehensive and systematic review of the original 183 national metrological benchmarks for preservation and maintenance in China. . The result has been announced by the AQSIQ according to law (AQSIQ announcement No. sixty-second 2017). Among them, 35 metrological benchmarks were approved by technical transformation and upgrading, 12 benchmarks were suspended and technical transformation and upgrading were started, and the abolishment of the 6 items that did not meet the needs of current metrology development work and the backward technical level were eliminated. The latest "People's Republic of China National Metrology datum list" compiled by the State Quality Inspection Administration (AQSIQ) has included China's current effective legal 177 national metrological benchmarks and publicly released to the society.
Twenty-first Century is the century of quality. Improving quality is the foundation of national development, the way to build a country and the strategy of a powerful country. Metrology is the technical guarantee for controlling quality and creating quality, and is an important national quality infrastructure. Measurement technology progress is directly related to technological innovation in various fields, and it is the core of upgrading industrial competitiveness to solve key common technical problems for the industry.
The index and technical level of the national metrology standard represent the highest measurement capacity of the state and one of the important signs of the national core competitiveness.
The improvement of measurement benchmark ability will drive the improvement of product quality.
The 35 metrological benchmarks for this release involve 9 fields of mechanics, geometry, ionizing radiation, chemistry, radio, acoustics, optics, electromagnetic and thermal engineering. At the press conference, the president of the Metrology Institute of China made a technical interpretation of the newly released 35 National Metrology benchmarks from the perspective of technology and application.
