Run Number	1	2
Mass of Empty Pycnometer (g)	23.91	23.91
Mass of Sample & Pycnometer (g)	36.69	37.06
Mass of Sample Added to Empty Pycnometer (g) ms	12.78	13.15

Density of Sample (kg/m3)	1307	1296
Mean Result (kg.m-3)	1302

Conclusions:

Under the conditions of the study, the relative density of the test material was determined to be 1.302 and the density was determined to be 1302 kg.m-3 at 20 °C.

Executive summary:

The relative denisty of the test material was investigated in a study which was performed under GLP conditions and in accordance with the standardised guidelines OECD 109 and EU Method A.3.

The relative density of the test material was determined using the pycnometer method. The density was calculated from the difference in weight between the full and empty pycnometer and its known volume. The tests were run at a constant temperature of 20 °C and at least two measurements were performed.

The relative density was calculated as the ratio between the mass of a volume of the test material, determined at 20 °C, and the mass of the same volume of water, determined at 4 °C.

Under the conditions of the study, the relative density of the test material was determined to be 1.302 and the density was determined to be 1302 kg.m-3 at 20 °C.

Additional information

The relative denisty of the test material was investigated in a study which was performed under GLP conditions and in accordance with the standardised guidelines OECD 109 and EU Method A.3. The study was assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
