- Type:
- relative density
- Density:
- 0.97
- Temp.:
- 20 °C
- Conclusions:
- The relative density of the test material has been determined to be 0.816 at 20.0 ± 0.5°C.
- Executive summary:
The relative density for Paraffin waxes (Fischer-Tropsch), full range, C15-50- branched and linear was determined using the pycnometer method, Method A.3 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
A glass pycnometer of 25 ml nominal capacity was cleaned and dried to a constant weight. Distilled water and test material were equilibrated at 20.0 +/-0.5 deg C. A calibration was carried out by determining the mass of distilled water required to fill the pycnometer. The pycnometer was then emptied and dried to constant weight. The mass of test material required to fill the pycnometer was then determined. The relative density was then calculated.
The relative density of the test material has been determined to be 0.816 at 20.0 ± 0.5°C.
