Results and mean values:

Parameter	Value	Unit	Standard Deviation	Relative Standard Deviation
Volume of Pycnometer	24.91	cm^3	0.0003	0.00%
Density of Test Item	1.0642	g/cm^3	0.0004	0.03%
Density of Test Item	1064.2	kg/m^3	0.4	0.03%
Relative Density of Test Item	1.0642		0.0004	0.03%

Conclusions:

The density of the test item was calculated as 1.0642 ± 0.0003 g/cm3 at 20.0 ± 0.2°C. This value is the mean of two independent determinations with the maximum error of a single determination.
Standard deviation was 0.0004 g/cm3, showing very good correlation of the two determinations.

Executive summary:

The study was performed in order to determine the density of test item according to OECD 109, resp. EU A.3 guideline, using a pycnometer.

The density of test item was determined to be 1.0642 g/cm3 at 20°C. (relative density = 1.0642).

Description of key information

The density of test item was determined to be 1.0642 g/cm3 at 20°C.
