Conclusions:
Under the conditions of this study, the relative density (D420) of the test material was 1.124.
Executive summary:

The relative density of the test material was investigated in accordance with the standardised guidelines OECD 109, EU Method A.3 and OPPTS 830.7300, under GLP conditions.

A fully automatic determination of the density was carried out with the help of MINIDENS Density Meter. The instrument operates as a fully automatic air comparison pycnometer.

The measured value was 1124 ± 3.79 kg/m³.

Under the conditions of this study, the relative density (D420) of the test material was 1.124.
