Mean reference cell volume: 90.748 cm3

Mean sample cell volume: 149.018 cm3

As the reference cell volume and sample cell volume were within the defined tolerance (90.953 ± 1.0 cm3 and 149.225 ± 1.0 cm3, for the reference and sample cell volumes respectively), the gas comparison pycnometer was therefore considered acceptable for use.

Temperature : 22.3 ± 0.5 °C

Conclusions:
The density of the test item has been determined to be 1.77E+03 kg/m3 at 22.3 ± 0.5 °C, thereby giving a relative density of 1.77.
Executive summary:

A study was conducted to evaluate the density of the test substance in accordance with EU Method A.3 and OECD Guideline 109. Using a gas comparison pycnometer, the density was determined to be 1.77E+03 kg/m3 at 22.3 ± 0.5 °C, thereby giving a relative density of 1.77.

Description of key information

The density was determined to be 1.77E+03 kg/m3 at 22.3 ± 0.5 °C, thereby giving a relative density of 1.77.

Key value for chemical safety assessment

Relative density at 20C:
1.77
