Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Using the pycnometer method, a density of
1.2078 g/cm3 ± 0.0001 at 20.0 ± 0.2 °C
was measured. This value is the mean of two independent determinations with the maximum
error of a single determination.
Standard deviation calculated with 0.0004 g/cm3 shows good correlation of the two determinations.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.208
Additional information
This study was performed in order to determine the density of Tar wood.
The density is one of the fundamental physico-chemical properties of a chemical substance.
The density was calculated from the difference in weight between a full and empty
pycnometer and its known volume.
The density of Tar wood was calculated as 1.2078 ± 0.0001 g/cm3 at 20.0 ± 0.2 °C, which
is the mean of two values. Precision of the value is given as maximal error of determination.
Standard deviation calculated with 0.0004 g/cm3 shows good correlation of the two determinations.
Therefore, the study is considered valid.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
