Description of key information
The density of the test item was measured according to EU Method A.3 and GLP with the pycnometer method. The average density of the test substance is (1489 ± 6) kg/m3and the relative density of the test substance (D23/4) is 1.489 ± 0.006.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.489
Additional information
For solids D23/4 is equal to D20/4 within the experimental error.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
