The solvent Density (F) was determined to be 0.8963 g/mL.

The %RSD acceptance criterion for the triplicate determinations was met.

Conclusions:
Under the conditions of this study, the mean density of the test material was 1.471 ± 0.056 g/mL at 19.7°C.
Executive summary:

The density of the test material was investigated in accordance with the standardised guideline OECD 109, under GLP conditions.

The test material density determination was performed in triplicate from representative subsamples using the Pycnometer method. Oil of turpentine was used as the solvent. The solvent density was determined to be 0.8963 g/mL.

The %RSD acceptance criterion for the triplicate determinations was met.

Under the conditions of this study, the mean density of the test material was 1.471 ± 0.056 g/mL at 19.7°C.
