Conclusions:
The density of the test item at 20ºC was 1.24 g/cm3 (1.24 × 103 kg/m3). The relative density was 1.24.
Executive summary:

A gas comparison stereopycnometer was used for the determination of the density and relative density of the test item according to OECD Guideline 109 and EU Method A.3. The density of the test item at 20ºC was 1.24 g/cm3 (1.24 × 103 kg/m3). The relative density was 1.24.

Description of key information

A gas comparison stereopycnometer was used for the determination of the density and relative density of the test item according to OECD Guideline 109 and EU Method A.3. The density of the test item at 20ºC was 1.24 g/cm3 (1.24 × 103 kg/m3). The relative density was 1.24.
