Results of the measurement of the density of the test item

Test No.	Temperature [°C]	Amount of test item [g]	Average sample volume [cm³]	Density [g/cm^3]
1	20	9.77	6.13507	1.59248
2	20	9.5	5.95933	1.59414
Mean				1.593

Conclusions:

Relative density: 1.59 at 20 °C

Executive summary:

The relative density of the test itemwas determined by air comparison pycnometer, according to the procedures outlined into the OECD guideline 109. The density was determined at a temperature of 20 °C ± 0.01 °C. A pressurized gas (He) was expanded from a pressurized reference chamber into a sample chamber, in which the test item is placed under atmospheric pressure; the volume of the sample and the reference chambers were exactly known. Using the free gas volume of the sample chamber, the volume of the test item in the sample chamber were calculated and by measuring the mass of the test item the density is determined.

Two tests with different amounts of the test item were performed.

The relative density was obtained by dividing the measured density of the test-item by the density of water at 4 °C (0.9999750 g/cm³).

The mean density of the test item at 20 °C resulted to be 1.593 g/cm³, therefore the relative density was calculated as 1.59.

Conclusion

Relative density: 1.59 at 20 °C
