VP= Volume of the calibrated pycnometer [cm3]

mp= Mass of the empty pycnometer [g]

mPTI= Mass of the pycnometer filled with test item [g]

TP= Temperature of the pycnometer at point of measurement [°C]

pTI= Density of the test item [g/cm3]

CV = Coefficient of variation [%]

 

The relative density of the test item was calculated to be 0.9410.

 

Temperature Control

During the equilibration time the temperature was kept constant at 20.0 ± 0.1 °C, for temperatures at moments of weighing (TP).

 

Validity Criteria

The temperatures at moments of weighing were kept constant within 20.0 ± 0.1 °C. 

The relative standard deviation (RSD) of three replicate measurements was 0.009%.

Conclusions:
The substance is less dense than water.
Executive summary:

The relative density of the test substance was measured under GLP according OECD 109 / EU A3 guideline, pycnometer method. The sample weight was measured in triplicate at 20 °C, and the mean relative density was calculated from the nominal volume of the pycnometer.

The density of the test substance at 20 °C was determined to be 0.9410 g/cm3 corresponding to 941.0 kg/m3. The relative density D20/4 of the test substance under liquid form has been calculated to be 0.9410.

Description of key information

The substance is less dense than water.

Key value for chemical safety assessment

Relative density at 20C:
0.941

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study. The result is retained as key data.
