- Conclusions:
- The test substance has a releative density of 1.47 at 20 °C.
- Executive summary:
The relative density of the test substance was determined with the pycnometer method according to OECD guideline 109, EU method A.3 and OPPTS 830.7300. A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The density of the test item was calculated from its weight and volume. The measured density of the test substance was 1466.0 ± 16.04 kg/m³. The relative density of the test substance is 1.47.

The obtained density values are 1.4274 g/mL and 1.4254 g/mL for replicates R1 and R2 respectively. The calculated mean density value of the replicates was found to be 1.4264 g/mL with 0.07 % of RSD. The relative density (D_4^20) is given by the value of the density (ρ).

Additional information
The relative density of the test item was determined in two reliable studies according to OECD guideline 109, EU method A.3 and OPPTS 830.7300 (pycnometer method). The density studies obtained a relative denity of the test substance of 1.4 (Bioneeds 2018, Toxi-Coop 2018).
