Abstract In view of the fact that the density balance can only be calibrated in the liquid mode and can not be calibrated in the solid mode, a kind of hook-type cavity glass weight is developed as solid density standard, the density balance solid measurement mode is calibrated, and a solid density balance calibration system is proposed. Calibration experiments on solid density balance show that the expanded uncertainty of the calibration results is 0.0016g/cm3 (k=2).
