The mean density for the two test series is 1.07 g/cm3.
Conclusion: The relative density of the test item at ambient temperature (compared to water at 4 °C) was determined to be: D4R= 1.07
Description of key information
Relative density: 1.07 at 20 °C (OECD 109, air comparison pycnometer)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.07
