Conclusions:
The mean relative density mean value of the test item using the gas comparison method by stereopycnometryer was: D (at room temperature
20.6°C / 4°C) = 1.878 ± 0.004.
Executive summary:

Relative density of Calcium tartrate was determined according to OECD Guideline 109.

The mean relative density mean value of the test item using the gas comparison method by stereopycnometryer was: D (at room temperature

20.6°C / 4°C) = 1.878 ± 0.004.
