- Abstract:
- In this study, the air density has been determined with relative uncertainty of 1,75 × 10-5 (k = 1) by using experimental method to establish SASO NMCC’s mass scale at the highest accuracy. Hollow and tabular type buoyancy artefacts, which have the same surface area, but a different volume of 279, 1196 cm3, have been compared under the vacuum of 5 × 10-6 mbar and in air by using 1 kg vacuum mass comparator.
