- Conclusions:
- The relative density (D4') of the test substance was found to be 1.04
- Executive summary:
The relative density of the test substance was determined relative to purified water using a pyknometer at 21°C. Aqueous Tween 80 (0.1% v/v) was employed as the displacement liquid.
The relative density (DT ) of solids and liquids is defined as the ratio of the mass of a volume of substance to be examined, determined at T°C, and the mass of the same volume of water at 4°C.
The relative density (D4') of the test substance was found to be 1.04
The relative density (D4') of the test substance was found to be 1.04.

Using
the helium pycnometer method, the density of the test substance was
obtained at room temperature (approximately 20°C). The
mean density result was0.9983
± 0.0057 g/cm3
(998.3 ± 5.7 kg/m3). The
results of the density determinations are presented in the Table below .
