The density of the test item determined two times with
individually prepared samples. Since the relative deviation between two
measurements was ≤ 0.5 % the quality criteria of the measurement were
fulfilled. The data, the mean of the densities, and its relative
deviation are presented in Table 2 and Table 3.

relative deviation [%]:
The mean relative density (D204)
of the test itemwas determined to be 1.5726 relating to the nominal
density of water at 4 °C (0.999972 g/cm3).
EU Method A.3. – The relative density of the test item was determined
utilising an air comparison pycnometer. The procedure employed was
designed to be compatible with Method A.3. Relative Density of
Commission Regulation (EC) No 440/2008 of 30 May 2008.
Two determinations were carried out. An instrumentation check was
performed by measuring of the volume of the reference sphere. Aliquots
of test item (5.5 – 5.6 g) were placed in the measuring cell. The
density of the test item was determined. This determination was
performed twice at 20.0 °C ± 0.2 °C to acquire an average value.
The relative density (D420) of the test item was
calculated to be 1.5726, based on the ratio of the measured density of
the test item relative to the density of water at 4 °C.
