Conclusions:
Under the conditions of this study the density of the test material was determined to be 0.687 g/cm³.
Executive summary:

The density of the test material was investigated in accordance with the standardised guidelines OECD 109, ISO 3507 and NF T 20-053, using the pycnometer method.

The pycnometer was weighed empty. After this it was filled with water and tempered in a water bath (22 °C) for one hour and weighed again. In the next step, the test material was weighed in and the pyconometer was restocked with water and tempered for one hour in a water bath (22 °C) and the complete weight was determined.

Under the conditions of this study the density of the test material was determined to be 0.687 g/cm³.

Description of key information

Under the conditions of the study the density of the test material was 0.687 g/cm³.

Key value for chemical safety assessment

Relative density at 20C:
0.687

Additional information

The relative density of the test material was investigated in accordance with the standardised guidelines OECD 109, ISO 3507 and NF T 20-053, using the pycnometer method. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).

The pycnometer was weighed empty. After this it was filled with water and tempered in a water bath (22 °C) for one hour and weighed again. In the next step, the test material was weighed in and the pyconometer was restocked with water and tempered for one hour in a water bath (22 °C) and the complete weight was determined.

Under the conditions of this study the density of the test material was determined to be 0.687 g/cm³.
