- Type of method:
- pycnometer method
- Key result
- Type:
- relative density
- Density:
- 0.993
- Temp.:
- 20 °C
- 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.
Reference
As the difference between two results was less than 0.03 g/ml then two trials were enough.
