As legal measuring instruments, all weighing instruments, whether manufactured, sold, in use, repaired, or imported, must be calibrated according to verification regulations. So what are these verification regulations? What are their characteristics?

Verification regulations refer to technical provisions for measuring instruments, including metrological performance, verification items, verification conditions, verification methods, verification cycles, and the handling of verification results. Their primary function is to uniformly assess the quality of measuring instruments, implement supervision, and ensure accurate and consistent measurement values ​​across the country. Verification regulations serve as the legal basis for measuring instrument testing and serve as the link between production, use, and measurement.

Weighing instrument verification regulations are primarily the responsibility of grassroots metrology departments (including those within manufacturing industries and user organizations). As we all know, weighing instruments are used throughout the country, numbering tens of thousands. They play a role in nearly every aspect of life, from daily life to scientific research and experiments, from transportation to coal metallurgy, from packaged food to petrochemicals, and many of them play a crucial role. The best way to assess and verify their performance is through calibration, with the results providing the final word. Faced with this vast and widespread nationwide scale calibration effort, the only solution is to adhere to the principles of economic rationality, local proximity, and the collective efforts of grassroots metrology departments.
