- Density:
- 1.106 g/cm³
- Temp.:
- 21.6 °C
- Conclusions:
- The relative density of the test item was determined to be 1.11 at 20 °C
- Executive summary:
A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. Therefore the density was measured at a temperature of 21.6 °C using a Micrometrics MultiVolume Pycnometer. Two test series with different weights were performed. The mean density at 21.6 °C was determined to be 1.06 g/mLand the mean relative density of the test item at 20 °C with respect to water at 4 °C was determined to be 1.11.
