SIMULTANEOUS SUB-MULTIPLE CALIBRATION FOR BOTH MASS AND VOLUME OF WEIGHTS USING A MASS COMPARATOR SYSTEM WITH AN AIR-TIGHT CHAMBER

Abstract

The National Metrology Institute of Japan has established a simultaneous sub-multiple calibration method for both mass and volume of weights using a newly developed mass comparator system with an air-tight chamber. In order to verify validity of this method, the sub-multiple calibrations of the masses and volumes are simultaneously made for weights from 100 g to 10 g of a weight set, and the expanded uncertainties of these calibrated results have been estimated.
