- Executive summary:
Method
Relative density was determined by means of pycnometer method as per recommendations of OECD 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.
Result
Relative density: 1.666 at 20 °C.
Reference
Absolute density of a substance (δ) is calculated as:
δ subs = WS / V subs = WS / (V pyc – V hex ) = WS / (V pyc – WH2 / δ Hex ) = WS / (V pyc – WH 2 * V pyc / WH1 ) Relative density (D204) is calculated as: δ subs / 0.999973

Description of key information
The relative density of the test substance was determined to be 1.666.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.666
Additional information
Relative density was determined by means of pycnometer method as per recommendations of OECD 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume. The relative density was determined to be 1.666 at 20 °C.
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).
