- Key result
- Type:
- relative density
- Density:
- 3.63
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item at 20 °C (compared to water at 4 °C) was determined to be 3.63.
- Executive summary:
A study was conducted according to Regulation (EU) No. 440/2008 method A.3 and OECD Guideline No. 109 to determine the relative density of the test item. The density was determined in two assays. Using the pycnometer method the mean density of the test item at 20 °C was determined to be 3.63 g/cm3. The relative density of the test item at 20 °C (compared to water at 4 °C) was determined to be D420 = 3.63.
Reference
Two test series were performed at 20.1 °C. The results are summarized in the Table.

Mean density ρPR for the two test series: 3.63 g/cm3
Relative density (compared to water at 4 °C) D4R:
D4R = ρPR/ρW4 = 3.63 g/cm3 / 1.00 g/cm3 = 3.63 ± 0.01
Description of key information
The relative density of the test item at 20 °C (compared to water at 4 °C) was determined to be 3.63.
Key value for chemical safety assessment
- Relative density at 20C:
- 3.63
