Conclusions:

Under the conditions of this study the density of the test material was 1335 kg.m^-3 at 20 °C. The relative density was 1.335.

Executive summary:

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

The density of the test material was calculated from the difference in weight between the full and empty pycnometer and its known volume (25 mL). The test was run at a constant temperature, 20 °C, and at least two measurements were performed.

Under the conditions of this study the density of the test material was 1335 kg.m^-3 at 20 °C. The relative density was 1.335.
