Conclusions:
The density of the test item has been determined to be 1.13 x 10³ kg/m³ at 19.0 ±0.5 °C and a relative density of 1.13.
Executive summary:

The determination of the relative density of the test item was carried out by the gas comparison pycnometer method, using a procedure designed to be compatible with Method A.3 Relative Density of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 109 of the OECD Guidelines for Testing of Chemicals, 02 October 2012. The density of the test item has been determined to be 1.13 x 10³ kg/m³ at 19.0 ±0.5 °C and a relative density of 1.13.
