Key result
Type:
relative density
Density:
1.41 other: dimensionless
Temp.:
20 °C
Remarks on result:
other: mean value

The individual measurements were obtained with an accuracy of < 0.02 g/cm3. In according with the guideline, the density of the test item is thus given as the mean value.

Conclusions:
The mean density of the test item was 1.41 g/cm3 at 20°C; the mean relative density was 1.41.
Executive summary:

The relative density of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.3 method and OECD Guideline No. 109, using the pycnometer method. The mean density of the test item was 1.41 g/cm3 at 20°C; the mean relative density was 1.41.

Description of key information

The relative density of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.3 method and OECD Guideline No. 109, using the pycnometer method. The mean density of the test item was 1.41 g/cm3 at 20°C; the mean relative density was 1.41.

Key value for chemical safety assessment

Relative density at 20C:
1.41

Additional information

The relative density of the test item was determined in one GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.
