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 0.9920 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 = 0.99

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 at 20 °C+/-0.01 °C (compared to water at 4 °C) is D420 = 0.99.

 

Conclusions:
A relative density value of 0.99 was determined for the test substance according to EU Method A.3.
