The relative density of Leuco Sulfur Blue 9 is 1.50. - Executive summary:
The purpose of this study was to determine the Relative Density of the Test Item.
A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The density of the test item was calculated from its weight and volume.The measured density ofLeuco Sulfur Blue 9 was 1503.1 ± 11.65 kg/m3.The relative density of Leuco Sulfur Blue 9 is 1.50.
