Conclusions:
Under the conditions of the test the mean relative density of the test material was 2.584 ± 0.003 at 20.3°C.
Executive summary:

The relative density of the test material was assessed according to OECD Test Guideline 109 and EU Method A.3 using a gas pycnometer.

Two series each of three measurements on the same test material sample were performed. The sample cell was weighed, filled with at least two thirds of the test material and reweighed. The samples weight was then determined by difference. The measurements were done after purging. The density in grams per cm³, and relative density were calculated.

The mean relative density from the three runs in Assay 1 was 2.856 ± 0.002 at 20.4°C.

The mean relative density from the three runs in Assay 2 was 2.851 ± 0.001 at 20.1°C.

The mean relative density of the test material was 2.584 ± 0.003 at 20.3°C.

Description of key information
