Conclusions:

Relative density: 1.396 at 20 °C

Executive summary:

Relative density was determined by means of a pycnometer as per recommendations of OECD 109. Density was calculated from the difference in weight between the full and empty pycnometer and its volume.

Conclusion

Relative density: 1.396 at 20 °C
