The density of the substance was determined to be 824.0 kg/m3 at 20°C by immersed body method (buoyancy method for liquids).

Tables 1 and 2 demonstrate the test results.

Notes) Density = Weight gain due to the immersion of the body in liquid sample/Volume of the body (11.369 cm 3)

Relative Density (D20/4) = Density at 20 °C/ Density of Water at 4 °C

Density of water at 4 °C = 1 000 kg/m

Conclusions:
The density of the substance was determined to be 824.0 kg/m3 at 20 °C.
Executive summary:

The density of the substance was determined using the immersed body method (buoyancy method), in accordance with OECD Guideline 109, October 2nd 2012 and EU method A.3.

The density of the substance was determined to be 824.0 kg/ m3 at 20 °C. The relative density was determined as 0.824 (D20/4).
