To verify the calibration capability of a certain laboratory's weights,a weight measurement audit was con-ducted.Taking the F1 grade 20 kg weight as an example,the paper introduces the application process for weight mea-surement audit,weight calibration process,processing of calibration data,and analysis of measurement audit results.The weight measurement audit conclusion of a certain laboratory is satisfactory,which indicates that the weight cali-bration capability of the laboratory meets the requirements and can carry out weight calibration work.
