Results of the measurement of the density of the test item

Test No.	Temperature [°C]	Test item chamber size	Reference vessel No.	Weight in of test item [g]	Density [g/cm³]*
1	20	Small (25.62 cm³)	76 (21.35 cm³)	11.81	2.09151
2	20	Small (25.62 cm³)	76 (21.35 cm³)	12.84	2.08610

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

The mean density of the test item at 20°C is 2.08881g/cm³ (SD = 0.0045, RSD = 0.18%). The relative density D₄²⁰is 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= 2.09

Conclusions:

According to OECD Test Guideline 109 (1995) and EC 440/2008 Part A method A.3., the relative density of vanadium, oxalate complexes at 20°C ± 0.01°C (compared to water at 4°C) (D420) is 2.09.
