Results

Two tests with different amounts of the test item were performed to determine the relative density D420 at a temperature of 20 + 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 1.26545 g/cm3. The relative density D420 is calculated by dividing the density of the test time by the density of water at 4 °C (0.9999750 g/cm3).

The relative density is D420 = 1.27

 

Final Results

According to OECD Test Guideline 109 (1995), EC 440/2008 Method A.3., OECD and OCSPP Test Guideline 830.7300 (2002), the relative density D420 of the test item 20 °C + 0.01 °C (compared to water at 4 °C) is D420 = 1.27.

Conclusions:
A relative density value of 1.27 was determined for the test substance according to E.U. Method A.3.
