Reference material quality system
The quality system of the Institute of Chemical Metrology and Analytical Sciences of the Chinese Academy of Metrology: In order to ensure the accuracy and reliability of the quality value of the reference material, the research on the standard and high accuracy calibration method and preparation technology was actively carried out. All developed national level reference materials have passed the international peer review organized by the International Bureau of Metrology (BIPM) and entered the national measurement calibration capability (CMC) mutual recognition directory. The peer review will be held regularly according to international practice. At the same time, the standard materials covering GBW and BW have been established; A comprehensive quality management system in accordance with ISO Guide 34 and 17025. Strictly control the quality of reference materials according to the process shown in the figure below, and take part in the international comparison and capability verification organized by the International Bureau of Metrology or other international organizations such as CCQM, CCM, ASTM as an effective means of external quality control.
