- Executive summary:
The relative density of the substance was determined using the pycnometer method, according to the OECD guideline 109.
The density of solids is determined with a calibrated gas comparison pycnometer at a temperature of 20 ± 0.01 °C. By measuring the mass of the test item, the density is determined.
The mean density of the test item at 20 °C is 1.447 g/cm³. The relative density D420is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).
Conclusion
Relative density: 1.45 at 20 °C
Reference
| Test No. | Temperature [°C] | Amount of test item [g] | Average sample volume [cm³] | Density [g/cm³] |
| 1 | 20 | 7.79 | 5.40997 | 1.43994 |
| 2 | 20 | 7.85 | 5.39793 | 1.45426 |
The mean density of the test item at 20 °C is 1.447 g/cm³.The relative density is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).
