- Key result
- Type:
- relative density
- Density:
- 0.988
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item was determined to be 0.988 at 20 °C compared to the density of water at 4 °C.
- Executive summary:
The density was determined using a gas comparison pycnometer according to Regulation (EC) No 440/2008 Method A.3 and OECD Test Guideline 109. The test item was filled into the empty, clean sample cell and the weight was measured. The volume of the test item was measured in inert gas (helium) in a cylinder of variable calibrated volume. The density tester determined automatically the volume and the density of the sample. Two parallel tests were performed. The mean density of the test item was determined to be 0.988 g/cm³. Therefore, the relative density of the test item was determined to be 0.988 at 20 °C compared to the density of water at 4 °C.
Reference
Test No. | Temperature / °C | Amount of test item / g | Average sample volume / cm³ | Density / g/cm³ |
1 | 20 | 5.82 | 5.90 | 0.986 |
2 | 20 | 5.83 | 5.89 | 0.989 |
The mean density of the test item at 20 °C is 0.988 g/cm³.The relative density is calculated by dividing the density of the test item at 20 °C by the density of water at 4 °C (0.9999750 g/cm³). The relative density of the test item is 0.988.
Description of key information
