Evaluation, data handling:

The density (r) of a test item is the quotient of the mass (m) and the volume (V) of that substance at a specific temperature.

SI unit is in [kg/m³]. 1 [g/cm³, g/mL] corresponds to 1000 [kg/m³]

The relative density of solids or liquids is the ratio between the mass of a volume of substance to be examined, determined at 20 °C and the mass of the same volume of water, determined at 4 °C. The relative density has no dimension.

The density (r) of water at 4 °C is 1 g/mL. If the test is performed at 20 °C ± 1 °C, the relative density () is given by the value of the density (r).

Applicant's summary and conclusion

Conclusions:
The measured density of Leuco Sulfur Red 14 was 1329.4 +/- 31.75 kg/m3.
The relative density of Leuco Sulfur Red 14 is 1.33.
Executive summary:

The purpose of this study was to determine the Relative Density of the Test Item, Leuco Sulfur Red 14.

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 of Leuco Sulfur Red 14 was1329.4±31.75 kg/m3.

The relative density of Leuco Sulfur Red 14 is 1.33.
