- Key result
- Type:
- relative density
- Density:
- 1.25
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test item is 1.25.
- Executive summary:
In a GLP study according to OECD Test Guideline 109 and EU Method A.3 the relative density D420 of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is determined to be 1.25.
Reference
Two tests with different amounts of the test item were performed to determine the relative density at a temperature of 20 °C ± 0.01 °C. Results are summarized in Table 1.
Table 1: Results of the density measurement
Test | Temperature [°C] | Amount of test item [g] | Average sample volume [cm3] | Density [g/cm3] |
1 | 20 | 4.869 | 3.883 | 1.254 |
2 | 20 | 4.947 | 3.945 | 1.254 |
The mean density of the test item at 20 °C is 1.254 g/cm³.
To calculate the relative density D420 at 20 °C, the measured density of the test item at 20 °C is divided by the density of water at 4 °C (0.9999750 g/cm³), resulting in D420 of 1.25.
Description of key information
In a GLP study according to OECD Test Guideline 109 and EU Method A.3 the relative density D420 of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is determined to be 1.25.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.25
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
