- Density:
- 0.949
- Temp.:
- 20 °C
- Type:
- density
- Density:
- 0.949 g/cm³
- Temp.:
- 20 °C
- 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 was measured in triplicate at 20 °C, and the mean relative density was calculated.
The relative density D20 4 of the test substance has been determined to be 0.9491.

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 D20 4 of the test item was calculated to be 0.9491.
Validity Criteria
The temperatures at moments of weighing were kept constant within 20.0 ± 0.1 °C.
The coefficient of variation of the three replicate measurements was < 2 %. No outlier was ascertained.
Description of key information
The substance is less dense than water.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.949
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EU method and under GLP, is available. It is considered as a key study. The result is retained as key data.
