Type:
relative density
Density:
0.993
Temp.:
20 °C

As the difference between two results was less than 0.03 g/ml then two trials were enough.

Raw data to calculate relative density:

No. of test

Weight of empty pycnometer, m0

Weight of pycnometer with water, m1

The average measured absolute density of the tested material at 20 °C temperature was 0.993 g/ml.

The average calculated relative density of the tested material at 20 °C temperature was 0.993.

Conclusions:
The relative density of the test substance was determined to be 0.993 at 20 ºC.
Executive summary:

The density determination of the tested material, using the Gay-Lussac pycnometer in accordance with EU Method A.3 (CIPAC MT 3.2) was based in measuring the mass of the tested liquid contained by the pycnometer and defining its volume. The average calculated relative density of the tested material at 20 °C temperature was 0.993.

Description of key information

Key study: EU method A.3. GLP study. The relative density of the test substance was determined to be 0.993 at 20 ºC.

Key value for chemical safety assessment

Relative density at 20C:
0.993
