Abstract

This paper proposes a method for applying mass comparator calibration results to mass value transfer. On the basis of analysing the main factors affecting the calibration results of the mass comparator, according to the international recommendation OIML R111-2004 and the requirements of the national metrology verification regulation JJG 99 2006 for the balance, the calibration results of the repeatability, eccentricity and partial indication error of the mass comparator are applied to the uncertainty assessment of the mass value transmission. The results show that the method calculation can apply the calibration results calculated by the mass comparator to the calculation of the OIML R111 2004 conversion mass measurement, and can also meet the requirements of JJG 99-2006 for the uncertainty of the measurement instrument synthesis standard not exceeding the maximum allowable error of the quality of the weight being inspected, and the larger standard uncertainty or the three synthetic standard uncertainties on the mass comparator certificate are directly selected. All effectively avoid the loss of volume transmission accuracy and waste of resources.
