Conclusions:
The relative density of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is 0.961.
Executive summary:

The relative density of the test item was determined using the calibration gas comparison pycnometer following OECD Guideline 109 and EU method A3. The study is considered reliable and relevant with no restrictions. In conclusion, the relative density (D420) of the test item at 20 ⁰C ± 0.01 °C (compared to water at 4 °C) is 0.961.
