(1) The traceability gas standard substance established for measurement has good uniformity and stability, can preserve the chemical composition and characteristic value of the substance, and transfer its value in different space and time. Therefore, the measurement results can be traceable through the application of Calibration gases.

(2) Transfer of quantity Calibration gas is a means to transfer quantity and achieve accurate and consistent measurement results. Through different grades of  Calibration gases, the instrument transmits the value of the si base unit to the actual measurement to ensure the accuracy of the measurement results.

(3) Promoting the development of measurement technology and quality supervision standard gas plays an important role in ensuring the consistency of product quality and inspection results, and ensuring the scientificity, authority and impartiality of technical supervision work. Calibration gases are inseparable from the formulation and identification of new instruments, metrological certification of quality inspection institutions, laboratory accreditation, and the formulation, verification and implementation of national and industrial gas product standards.

(4) To ensure the accuracy and consistency of measurement results Calibration gas can be used to calibrate or verify measuring instruments, evaluate the measurement process and the quality of various measurements, so as to ensure the consistency of different time and space measurements.
