Conclusions:
The relative density of the test item (obtained from two measurements) was 1.507 ± 0.001 at 20.6 °C
Executive summary:

The determination of the density was performed using pycnometer according to recognized guidelines (OECD 109, EU Method A.3) and under GLP. No deviation from the guidelines was observed during the study.

Before the determination of the test item density, the apparatus was checked with a reference substance. Based on the results obtained, the apparatus was considered as acceptable for use.

The relative density of the test item (obtained from two measurements) was 1.507 ± 0.001 at 20.6 °C

Description of key information

The relative density of the test substance was determined in a study performed with the pycnometer method according to recognized guidelines (OECD 109, EU Method A.3) and under GLP. The relative density of the test item) was 1.507 ± 0.001 at 20.6 °C

Key value for chemical safety assessment

Relative density at 20C:
1.507

Additional information

The relative density of the test item was investigated 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.
