The measured value was 913 ± 1.9 kg/m3, where density (ρ) of a substance is the quotient of the mass (m) and the volume (V) of that substance at a specific temperature.

The relative density (D420) is 0.913, where 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 is dimensionless.

Applicant's summary and conclusion

Conclusions:

The density of the registered substance was determined to be 913 kg/m3 and the relative density was determined to be 0.193.

Executive summary:

The relative density of the substance was assessed according to EC (A3) using the Pycnometer method. The density meter was calibrated using an aluminium calibration block and determined the density of the substance to be 913 kg/m3 and the relative density to be 0.193.
