MASS AND DENSITY DETERMINATION OF OIML E1 WEIGHT SET IN CZECH METROLOGY INSTITUTE

By Jaroslav Zůda

Abstract

Abstract – In this article we introduce the results of density and volume measurements of sub-gram and 1 kg weighs. At first the theoretical principles of such experiments are described. These include the uncertainty calculations. Sub-gram weights were measured in volume and mass comparators. The results are shown in the last part of this paper. The result is, that our primary mass laboratory can measure the density of milligram weight with uncertainty below 2000 kg/m 3 (k=2)
