* 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 1.9025 g/cm³.

The relative density D204 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          D204 =1.90.

Conclusions:
According to OECD Test Guidelines 109 (2012), Regulation EC No. 440/2008 Method A.3., the relative density D20/4 of the test item Potassium hexacyanocobaltate (III) at 20 °C ± 0.01 °C (compared to water at 4 °C) is D20/4 = 1.90.
