Conclusions:
The mean relative density of the test item was 1.206 ± 0.001 at 19.6 °C.
Executive summary:

The relative density of the 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 relative density of the test item was 1.206 ± 0.001 at 19.6 °C.

Description of key information

The relative density of the 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 relative density of the test item was 1.206 ± 0.001 at 19.6 °C.

Key value for chemical safety assessment

Relative density at 20C:
1.206

Additional information

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