- Type of method:
- oscillating densitimeter
- Key result
- Type:
- relative density
- Density:
- 0.93
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 0.930 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 test item was mostly solid, partly molten when it was delivered. In order to take a representative sample, the substance was completely molten at 40 °C and the substance remained liquid at ambient temperature. Therefore, the tests were performed with the liquid state of the substance. The sample was filled into the measuring cell of the density meter using a syringe. The test was performed at a temperature of 20 ± 0.01 °C. Three replicate determinations were carried out. The relative density of the test item was determined to be 0.930 at 20 °C compared to water at 4 °C.
Reference
Relative Density
The test item was given into the measuring cell using a syringe.
Test No. | Temperature / °C | Relative Density |
1 | 20 | 0.9296 |
2 | 20 | 0.9296 |
3 | 20 | 0.9296 |
The mean relative density of the test item at 20 °C is 0.9296.
The relative density at 20 °C compared to the density of water at 4 °C is 0.930.
Description of key information
