Applicant's summary and conclusion

Conclusions:
The relative density D 22/4 of the test article was determined to be 0.725.
Executive summary:

In a general physico-chemical properties study (13193), the test material was determined have a relative density of 0.725 at 22.0 °C by the pycnometer method based on Method A3 of Commission Directive 92/69/EEC.
