- Type of method:
- oscillating densitimeter
- Key result
- Type:
- relative density
- Density:
- 0.98
- Temp.:
- 20 °C
- Remarks on result:
- other: compared to water at 4 °C
- Conclusions:
- The relative density of the test item was determined to be 0.98 at 20 °C with respect to water at 4 °C.
- Executive summary:
A study was conducted according to OECD TG 109, Regulation (EC) No 440/2008 method A.3 and OPPTS 830.7300 to determine the relative density of the test item. Therefore the density was measured at a temperature of 20 °C ± 0.01 °C using the oscillating densitometer. An initial calibration with purified-water was carried out. Subsequently three independent measurements of the test item were performed. The mean relative density of the test item at 20 °C with respect to water at 4 °C was determined to be 0.98.
Reference
The test item was aspirated (sucked) into the measuring cell through the aspiration tube.
