Results of the density measurements

Sample number Sample weight (g) Sample volume (cm3) Density (g/cm3)
1 1.2704 0.9085 1.3984
2 1.6522 1.1698 1.4123
3 1.9492 1.3802 1.4123
4 1.9512 1.3989 1.3949
5 1.7982 1.2604 1.4267
Mean: 1.4089
Confidence interval (95 %): 0.01578
RSD %: 0.9

The measured density of test item was 1408.9 ± 15.78 kg/m3.

Conclusions:
Relative density: 1.41 at 20 °C
Executive summary:

Relative density was determined by means of a pycnometer as per recommendations of OECD guideline 109. A known weight of the test item was placed in the sample cell and its volume determined by the density tester. The density of the test item was calculated from its weight and volume.

The measured density of test item was 1408.9 ± 15.78 kg/m3 and the relative density resulted 1.41, at 20 °C.

Conclusion

Relative density: 1.41 at 20 °C
