Discussion

Due to instability of the test material towards water (and water in the atmosphere), the test was carried out under a nitrogen atmosphere.

Applicant's summary and conclusion

Conclusions:
The relative density of the test material has been determined to be 0.906 at 20.0 ± 0.5°C.
Executive summary:

The relative density was determined using the pycnometer method, Method A3 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
