The mean density for the two test series is 1.7046 g/cm3.
Conclusion: The relative density of the test item at ambient temperature (compared to water at 4 °C) was determined to be: D4R= 1.70 ± 0.01
Description of key information
Relative density: 1.70 at 20 °C (OECD 109, gas comparison pycnometer)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.7
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
