- Key result
- Type:
- relative density
- Density:
- 1.71 other: dimensionless
- Temp.:
- 20 °C
- Conclusions:
- The mean relative density of the test substance was determined to be 1.71 at 20 °C.
- Executive summary:
The relative density of the test substance was determined by a gas comparison pycnometer method using a multi-pycnometer in accordance with OECD 109. The temperature was 20.0 °C during the calibration and the measurements. The results of the two measurements of the density for the test substance were: 1.7125 g/cm³ and 1.7128 g/cm³. The mean relative density of the test item was determined to be 1.7127at 20.0 °C (two samples).
Reference
The temperature was 20.0 °C during the calibration and the measurements. The results of the two measurements of the density for the test substance were: 1.7125 g/cm³ and 1.7128 g/cm³. The mean relative density of the test item was determined to be 1.7127 at 20.0 °C (mean of two test series).
