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.
