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.

Results of the measurement of the density of the test item

Test No.	Temperature [°C]	Amount of test item [g]	Average sample volume [cm³]	Density [g/cm³]*
1	20	8.83	6.68541	1.32079
2	20	9.45	6.88143	1.37326

* 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 1.34703 ± 0.03 g/cm³ (RSD = 1.95 %). 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 = 1.35.

Conclusions:

According to OECD Test Guideline 109 (2012), Regulation EC No. 440/2008 Method A.3. and OCSPP Test Guideline 830.7300 (2002), the relative density D4/20 of the test item 2-ethylhexanoic acid, cerium salt at 20 °C ± 0.01 °C (compared to water at 4 °C) is D4/20 = 1.35.

Description of key information

According to OECD Test Guideline 109 (2012), Regulation EC No. 440/2008 Method A.3. and OCSPP Test Guideline 830.7300 (2002), the relative density D₄²⁰ of the test item 2-ethylhexanoic acid, cerium salt at 20 °C ± 0.01 °C (compared to water at 4 °C) is D₄²⁰ = 1.35.
