Applicant's summary and conclusion

Conclusions:
The relative density (D420) is 1.726.
Executive summary:

This study has been performed in accordance with the study plan, Directive of the European Communities: Methods for the Determination of Physico-Chemical Properties (A.3), Organization for Economic Co-operation and Development Guideline No. 109, and the Principles of Good Laboratory Practice (GLP) and reported with a valid GLP certificate.

 

 A fully automatic determination of the density was carried out with the help of MINIDENS Density Meter. The measured value was 1726±1.67 kg/m3.

 

The relative density (D420) is 1.726.
