- Key result
- Type:
- relative density
- Density:
- 1.559
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test substance was determined to be 1.5586 at 20 ºC.
- Executive summary:
The objective of the study was to determine the relative density of the test substance according to OECD guideline 109 and EU method A.3 (gas comparison pyknometer method). The calibration showed that the cell volume was within acceptable limits. The test temperature was 20.0°C. The sample cell volume was 15.9698 cm3. The expansion cell volume was 74.5505 cm3. The weight of test substance measured was 3.4764 g. The mean density was 1.5586 g/cm3(1558.6 kg/m3), with a standard deviation (σn-1) of 0.0042. This gives a mean relative density value 1.5586 when compared to the literature value for water at 4°C, which is 1.0000 g/cm3.
