The relative density (D420) of the test substance was determined to be 1.6638 ± 0.01530 (with 95 % confidence interval) at 20 °C.

Conclusions:
The relative density (D420) of the test substance was determined to be 1.66 at 20 °C.
Executive summary:

The relative density was determined according to OECD guideline 109 (TOXI-COOP, 2017). The determination followed the air comparison pycnometer method. The density of the test substance was determined from five replicates at 20 °C. A relative density (D420) of 1.6638 ± 0.01530 (with 95 % confidence interval) at 20 °C was measured.
