- other: D 20 /4
- Key result
- Type:
- density
- Density:
- 0.979 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- Under the study conditions, the mean relative density value of the test substance was established at 0.979.
- Executive summary:
A study was conducted to determine the relative density of the test substance according to OECD Guideline 109, EU Method A.3 and OPPTS 830.7300. The relative density of the substance was determined in duplicate at 20°C using a gas comparison pycnometer. Under the study conditions, the mean relative density value of the test substance was established at 0.979 (Reingruber, 2017).

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
