Abstract:

Two methods for the volume determination of mass standards are compared. The conventional hydrostatic weighing method where the mass standards are immersed in water and weighings in air where the mass standards are subjected to a variation in air density of ± 10 % or less. The balance is installed in an air-tight chamber. Two kilograms were used and uncertainty analysis is compared
