Applicant's summary and conclusion

Conclusions:
The relative density of the test material has been determined to be 1.45 at 21.0 ± 0.5°C.
Executive summary:

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

The relative density of the test material has been determined to be 1.45 at 21.0 ± 0.5°C.
