Relative Density

Two tests with different amounts of the test item were performed to determine the relative density D420 at a temperature of 20 °C ± 0.01 °C.

* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.02 %.

The mean density of the test item at 20 °C is 3.29917 g/cm³. The relative density D420 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 = 3.30.

Conclusions:
According to OECD Test Guidelines 109 (2012), Regulation EC No. 440/2008 Method A.3. and EPA OCSPP Test Guideline 830.7300 (2002), the relative density D420 of aluminium vanadium tetraoxide (AlVO4) at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 3.30.

Description of key information
