Conclusions:
The relative density of the test item at 20 °C (compared to water at 4 °C) was determined to be 1.19.
Executive summary:

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item. Two test series were performed at 20.1 °C. Using the air comparison pycnometer method the density was determined to be 1.19 g/cm3 at 20.0 °C with a relative density of 1.19 with respect to water at 4 °C, respectively.

Description of key information

The relative density of the test item at 20 °C (compared to water at 4 °C) was determined to be 1.19.

Additional information

A study was conducted according to OECD TG 109 and Regulation (EC) No 440/2008 method A.3 to determine the relative density of the test item (reference 4.4 -1). Two test series were performed at 20.1 °C. Using the air comparison pycnometer method the density was determined to be 1.19 g/cm3 at 20.0 °C with a relative density of 1.19 with respect to water at 4 °C, respectively.
