- Executive summary:
A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 using an oscillating densitimeter to determine the relative density D420 of the test item. Two tests with the test item were performed at a temperature of 20 °C ± 0.01 °C. The mean density of the test item at 20 °C was 1.48 g/cm³. The relative density D420 was calculated by dividing the density of the test item by the density of water at 4 °C (1.00 g/cm³). The relative density was determined to be D420 = 1.48.
Reference
Two tests were performed at 20 °C.
Table 1: Results of the two tests
Measurement | Density ρP20 / g / cm3 |
1 | 1.4815 |
2 | 1.4815 |
Mean | 1.4815 |
Mean density ρP20 for the two test series: 1.48 g/cm3
Relative density (compared to water at 4 °C) D420:
D420 = ρP20 / ρW4 = 1.48 g/cm3 / 1.00 g/cm3 = 1.48 ± 0.01
Description of key information
The relative density of the test item was determined to be 1.48 at 20 °C (reference 4.4-1).
Key value for chemical safety assessment
- Relative density at 20C:
- 1.48
