Applicant's summary and conclusion
- Conclusions:
- The test substance is less dense than water. The density of the test item has been determined to be 973.2 kg/m3 at 23.0 ± 0.2°C.
Standard deviation was 5.2 kg/m3, showing good correlation of the two determinations. - Executive summary:
The relative density of the test substance was measured according OECD 109, by pycnometer method.Two runs were performed, and the mean density at 23.0 °C was calculated.
The density of the test item has been determined to be 973.2 kg/m3 at 23.0 ± 0.2°C.
Standard deviation was 5.2 kg/m3, showing good correlation of the two determinations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
