- Conclusions:
- Under the conditions of this study the pour density was 0.453 g/cm^3, and the tap density was 0.562 g/cm^3, therefore the density is between 453 and 562 kg/m^3 at 20 °C. The relative density is in the range of 0.453 to 0.562.
- Executive summary:
The relative density of the test material was determined in accordance with the standardised guidelines OECD 109 and EU Method A.3, under GLP conditions.
The pour and tap density was performed after analysis using the pycnometer and hydrostatic methods were found to be unsuitable due to the test material being soluble in all the immersion liquids investigated.
In the pour and tap method, a known weight of the test material was put into a glass measuring cylinder and its volume was measured. The cylinder was then raised and allowed to fall vertically through a distance of 25 mm on to a rubber/cork pad. The volume was measured again after 100 ‘taps’.
Under the conditions of this study the pour density was 0.453 g/cm^3 and the tap density was 0.562 g/cm^3, therefore the density is between 453 and 562 kg/m^3 at 20 °C. The relative density is in the range of 0.453 to 0.562.

Description of key information
Under the conditions of this study the pour density was 0.453 g/cm^3 and the tap density was 0.562 g/cm^3, therefore the density is between 453 and 562 kg/m^3 at 20 °C. The relative density is in the range of 0.453 to 0.562.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.453
Additional information
The relative density of the test material was determined in accordance with the standardised guidelines OECD 109 and EU Method A.3, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The pour and tap density was performed after analysis using the pycnometer and hydrostatic methods were found to be unsuitable due to the test material being soluble in all the immersion liquids investigated.
In the pour and tap method, a known weight of the test material was put into a glass measuring cylinder and its volume was measured. The cylinder was then raised and allowed to fall vertically through a distance of 25 mm on to a rubber/cork pad. The volume was measured again after 100 ‘taps’.
Under the conditions of this study the pour density was 0.453 g/cm^3 and the tap density was 0.562 g/cm^3, therefore the density is between 453 and 562 kg/m^3 at 20 °C. The relative density is in the range of 0.453 to 0.562.
