The density of the test item was determined twice with separate weighed samples. The quality criteria of the measurement  were fulfilled. The experimental data and the mean value are presented in the following table:

Weight of test item:

Weight No.	Vessel empty / g	Vessel + test item / g	Weight test item / g
1	9.2676	25.4748	16.2072
2	9.2674	24.3786	15.1112

 

Density of test item:

Weight No.	Determined sample volume / cm³	Weight test item / g	Temperature / °C	Density / g/cm³	Relative Density
1	9.05924	16.2072	20.0	1.7890	1.7891
2	8.44751	15.1112	20.0	1.7888	1.7889
		Mean	20.0	1.79	1.79

The relative density of the test item was determined to be 1.79 using the density of water at 4 °C (0.999972 g/cm³).

Description of key information

relative density: 1.79 at 20.0 °C (OECD 109)

Key value for chemical safety assessment

Relative density at 20C:

1.79

Additional information

The relative density was determined by air comparison pycnometer method according to OECD Guideline 109.
