* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.

The mean density of the test item at 20 °C is 1.69956 g/cm3. The relative density is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm3).

The relative density is D420 = 1.70.

Conclusions:
The relative density of the test item Oxonole Blue at 20 °C ± 0.01 °C (compared to water at 4 °C) is 1.70.
