- oscillating densitimeter
- Key result
- Type:
- relative density
- Density:
- 0.987
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 0.98706 at 20 °C compared to water at 4 °C.
- Executive summary:
The density was determined using an oscillating densitimeter according to Regulation (EC) No 440/2008 Method A.3 and OECD Test Guideline 109. The sample was filled into the measuring cell of the density meter using a syringe. After visual inspection on the camera image whether the measuring cell was filled without bubbles, the measurement was started. The test was performed at a temperature of 20 ± 0.5 °C. Five replicate determinations were carried out. The relative density of the test item was determined to be 0.98706 at 20 °C compared to water at 4 °C.
Reference
Performed at a temperature of 20 ± 0.5 °C. Five replicate determinations were carried out.
