Mean density : 1.01 x 10³ kg/m³

Relative density : 1.01

Temperature : 20.0 ± 0.5 °C

Conclusions:
The density of the test material was determined to be 1.01 x 10³ kg/m³ at 20.0 ± 0.5 °C and a relative density of 1.01.
Executive summary:

The relative density of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 109 and EU Method A.3, under GLP conditions, following the pycnometer method.

Under the conditions of the study the relative density of the test material was determined to be 1.01 at 20 °C.

Description of key information

The density of the test material was determined to be 1.01 x 10³ kg/m³ at 20.0 ± 0.5 °C and a relative density of 1.01.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

The relative density of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 109 and EU Method A.3, under GLP conditions, following the pycnometer method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

Under the conditions of the study the relative density of the test material was determined to be 1.01 at 20 °C.
