Test No. Temperature [°C] Amount of test item [g] Average sample volume [cm³] Density [g/cm³]*
1 20 12.35 6.82540 1.80942
2 20 12.48 6.87345 1.81568

* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.

Conclusions:
1.8126 at 20 °C
Executive summary:

The relative density of the test item was determined by gas pycnometer method, according to the OECD Guideline 109 (2012).

To calculate the relative density at 20 °C, the measured density of the test item at 20 °C was divided by the density of water at 4 °C (0.9999750 g/cm³).

The relative density D420 of the test item at 20 °C ± 0.01 °C (compared to water at 4 °C) resulted to be 1.8126.

Conclusion

1.8126 at 20 °C

Description of key information
