The following values were calculated:

First Determination			Error rel.	Error abs.
Temperature	20.2	°C		0.1
Density of water	0.998203	g/cm^3	2.00%	0.0002
Volume of Pycnometer	24.9232	cm^3

Volume of Pycnometer	24.9168	cm^3
Density of Test Item	1.0023	g/cm^3	0.0048%	0.0000

Mean values:

Parameter	Value	Unit	Standard Deviation	Relative Standard Deviation
Volume of Pycnometer	24.92	cm^3	0.0045	0.02%
Density of Test Item	1.0023	g/cm^3	0.0001	0.01%
Density of Test Item	1002.3	kg/m^3	0.1	0.01%
Relative Density of Test Item	1.0023		0.0001	0.01%

The density of the test item was calculated as 1.0023 ± 0.0001 g/cm³at 20.0 ± 0.2°C.

Conclusions:

The density of the test item was calculated as 1.0023 ± 0.0001 g/cm3 at 20.0 ± 0.2°C.

Executive summary:

The study was performed in order to determine the density of the test substance according to OECD 109 and EU Method A3 guidelines, using the pycnometer method.

The density of the test item was calculated as 1.0023 ± 0.0001 g/cm³at 20.0 ± 0.2°C.

This value is the mean of two independent determinations ± the standard deviation. Standard deviation shows very good correlation of the two determinations.

Description of key information

The density of the test item was calculated as 1.0023 ± 0.0001 g/cm3 at 20.0 ± 0.2°C.

This is a mean of two independent determinations.

Key value for chemical safety assessment

Relative density at 20C:
