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.

* Thee 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 6.34736 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 = 6.35.

Conclusions:
According to OECD TG 109 (2012) and Regulation EC No. 440/2008 Method A.3., the relative density of Aluminium lanthanum trioxide at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 6.35.

Description of key information

According to OECD test guidelines 109 (2012) and Regulation EC No. 440/2008 method A.3., the relative density D420 of the test item Aluminium lanthanum trioxide at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 6.35.

Key value for chemical safety assessment

Relative density at 20C:
6.35
