Temp.:
20 °C

Test No. Temperature [°C] Amount of test item [g] Average sample volume [cm³] Density [g/cm³]
1 20 7.79 5.40997 1.43994
2 20 7.85 5.39793 1.45426

The mean density of the test item at 20 °C is 1.447 g/cm³.The relative density is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

Conclusions:
Relative density: 1.45 at 20 °C
Executive summary:

The relative density of the substance was determined using the pycnometer method, according to the OECD guideline 109.

The density of solids is determined with a calibrated gas comparison pycnometer at a temperature of 20 ± 0.01 °C. By measuring the mass of the test item, the density is determined.

The mean density of the test item at 20 °C is 1.447 g/cm³. The relative density D420is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

Conclusion

Relative density: 1.45 at 20 °C
