Sample number Sample weight (g) Sample volume (cm3) Density (g/cm3)
1 0.6588 0.507 1.2995
2 0.7303 0.5602 1.3036
3 0.8758 0.6721 1.3031
4 0.8644 0.6633 1.3033
5 0.8674 0.662 1.3103
Mean: 1.304
Confidence interval (95 %): 0.00486
RSD %: 0.3

The measured density was 1304.0 ± 4.786 kg/m3.

Conclusions:
Relative density: 1.30 at 20 °C
Executive summary:

The relative density of the test item was determined by pycnometer method, according to the OECD Guideline 109.

To calculate the relative density at 20 °C, the measured density of the test item at 20 °C was divided by the density of water at 4 °C (ca 1 g/ml).

The relative density D420 of the test item at 20 °C ± 0.5 °C resulted to be 1.30.

Conclusion

Relative density: 1.30 at 20 °C

Description of key information
