Conclusions:
A fully automatic determination of the density was carried out with the help of MINIDENS Density Meter. The measured value was 1798 ± 4.15 kg/m3.
The relative density (D420) is 1.798.
Executive summary:

The density of the test material was performed in compliance with GLP and according to the guidelines EU Method A.3, OECD 109 and EPA OPTS 8300.7300. A fully automatic determination of the density of the test material was carried out with the help of a MINIDENS Density Meter. The measured value was 1798 ± 4.15 kg/m3. The relative density is 1.798
