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.

Description of key information

According to OECD TG 109 (1995), the relative density of vanadium, oxalate complexes at 20°C is 2.09.

Key value for chemical safety assessment

Relative density at 20C:
