Applicant's summary and conclusion

Conclusions:

Relative density ca. 1.13 (corresponds to D4(20))

Executive summary:

The test was carried out on one sample in duplicate.

Test equipment: Micrometrics AccuPyc 1330TC Pycnometer (displacement of helium gas) to measure the volume and hence the density of a substance.

Relative density: 1.13 at 20 °C.
