Results

Two tests with different amounts of the test item were performed to determine the relative density at a temperature of 20 °C ± 0.01 °C. Table 1 compiles the results.

* 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 1.2965 g/cm³. The relative density is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

Conclusions:
The test substance has a relative density of 1.297.
Executive summary:

According to OECD Guideline 109 (2012), Regulation EC No. 440/2008 Method A.3 and EPA OPPTS 830.7300 (2002), the relative density of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) is 1.297.

Description of key information
