Mean reference cell volume: 90.795 cm3
Mean sample cell volum: 148.940 cm3
As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3and 149.225 ± 1.0 cm3for the reference and sample cell volumes respectively) the gas comparison pycnometer was therefore considered acceptable for use.

Description of key information
The densitiy of the test item was found to be 1.69 x 103kg/m3at 20.0 ± 1.0 °C and therefore the relative density: 1.69, using a gas comparison pycnometer.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.69
Additional information
Density: 1.69 x 103kg/m3at 20.0 ± 1.0 °C and the relative density: 1.69.
