- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- The test item was used in its initial form.
- Type:
- relative density
- Density:
- 1.23 other: the relative density has no dimension!
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 1 225.8 kg/m³
- Temp.:
- 20 °C
- Conclusions:
- The measured density of the test item was 1225.8 ± 9.01 kg/m3, the relative density (D204) is 1.23.
- Executive summary:
The determination of the Relative Density of the test item was conducted following internationally accepted guidelines (OECD 109, EU method A.3) under GLP compliance. A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The test was performed at a temperature of 20 ± 0.5 °C. The density of the test item was calculated from its weight and volume.
The measured density of the test item was 1225.8 ± 9.01 kg/m3, the relative density (D204) is 1.23.
