Mean density of test material = 984.03 kg/m3
Density of water at 4°C = 1000.00 kg/m3
Relative density = 984.03/1000
= 0.98403
Description of key information
Relative density: 0.984 at 20.5°C (EU Method A.3)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.984
Additional information
Three measured relative density studies are available for the submission substance. A measured relative density of 0.984 at 20.5°C was determined for the substance using a pycnometer method in accordance with EU Method A.3 and in compliance with GLP. The result is considered to be reliable and is selected as key study.
In available supporting studies, a measured relative density of 0.9848 at 20°C was determined for the substance using an oscillating densitometer method in accordance with DIN 51757 and in compliance with GLP. Also, a relative density value of 0.9852 at 20°C was determined for the substance using a pycnometer method in accordance with EU Method A.3 and in compliance with GLP. The supporting studies are in good agreement with the key study.
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).
