The mean relative density is finally rounded to three decimals, because the volume of the pycnometer is reported with three significant decimals in the corresponding calibration certificate.

Conclusions:

The relative density of the test item is 2.108 at 20 °C.

Executive summary:

The relative density of the test item was determined according to OECD Guideline 109 using the pycnometer method. The relative density was calculated from the difference in mass of the empty and the filled pycnometer and its known volume by subtracting the known volume of the displacement liquid. The relative density of the test item at 20 °C as mean of two determinations was 2.108.

Description of key information

The relative density of the test item at 20 °C is 2.108.
