Results
| Determination | |||
| 1 | 2 | ||
| a | Mass of pycnometer (g) | 26.1900 | 26.1815 |
| b | Mass of pycnometer and distilled water at 20 deg C (g) | 75.9970 | 75.9955 |
| c | Mass of pycnometer and test material at 20 deg C (g) | 66.1627 | 66.2298 |
| d | Density of water at 20 deg C (kg/m3) | 998.23 | 998.23 |
Mean density of test material = 801.83 kg/m3
Density of water at 4 deg C = 1000.0 kg/m3
Relative density of Alkane 2 = 801.83 / 1000.0
= 0.80183.
The density was calculated using the following formula:
Density = d x (c-a) / (b - a) kg/m3
where:
a = mass of pycnometer (g)
b = mass of pycnometer and distilled water (g)
c = mass of pycnometer and test material (g)
d = density of water (kg/m3)
Applicant's summary and conclusion
- Conclusions:
- The relative density of Alkane 2 has been determined to be 0.80183 at 20 +/- deg C.
- Executive summary:
The experimental procedure used complied with that specified in Method A3 of Commission Directive 92/69/EEC (which constitues Annex V of Council Directive 67/548/EEC).
The relative density of Alkane 2 has been determined to be 0.80183 at 20 +/- deg C.
