- Executive summary:
A study was conducted to determine the relative density of the test substance according to OECD Guideline 109 and EU Method A.3. The density of a solid in any form can be measured at ambient temperature (R) with the gas comparison pycnometer. A constant temperature of the environment of the apparatus was regulated by an air-conditioning unit and controlled with a thermometer. The apparatus with the test substance was swept 10 times with 19.5 psi Helium. Thereafter, the valve to the expansion chamber (volume = Vr) was opened and a certain amount of gas (Helium, purity min. 99.99 %) was expanded from the measurement chamber (volume = Vc) containing the test substance to the expansion chamber. From the pressure drop from p1 to p2, the volume of the test substance Vs was calculated. Two test series with 3 measurements each were realised. Under the study conditions, the relative density of the test substance was determined to be 1.47 at 20.5 °C (compared to water at 4°C) (Dornhagen, 2016).

Results (details):
A measurement chamber with a volume of Vc= 141.8361 cm3 and an expansion chamber with a volume of Vr= 69.3167 cm3 were used. These volumes were selected to reduce a negative influence by the heterogeneous test substance on the measurement. Two test series with different weights were performed at ambient temperature (20.5 °C).
Results of the 1st test series (weight: 39.3059g):
p1/ psi, p2/ psi, Volume / cm3, DensityrPR/ g·cm-3:
- 1st measurement: 19.523, 12.188, 26.6579, 1.4745 respectively
- 2nd measurement: 19.559, 12.210, 26.6698, 1.4738 respectively
- 3rd measurement: 19.553, 12.208, 26.6260, 1.4762 respectively
Results of the 2nd test series (weight: 40.9924g):
p1/ psi, p2/ psi, Volume / cm3, DensityrPR/ g·cm-3:
1st measurement 19.539, 12.152, 27.8065, 1.4742
2nd measurement 19.522, 12.143, 27.7674, 1.4763
3rd measurement 19.562, 12.165, 27.8388, 1.4725
Mean volume and density: 27.8043 and 1.4743, respectively
Mean density rPR for the two test series: 1.47 g/cm3
Relative density (compared to water at 4 °C): D4R = 1.47 (20.5 °C)
Description of key information
The relative density was determined according to OECD Guideline 109 and EU Method A.3 (Dornhagen, 2016).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.47
