* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.2 %.
The mean density of the test item at 20 °C is 1.33121 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).
The relative density is D420=1.331.
Applicant's summary and conclusion
- Conclusions:
- Based on the pycnometer method the relative density of p-benzoquinone is 1,331.
- Executive summary:
According to OECD Test Guidelines 109 (2012) the relative density D420of the test item p-Benzoquinone at 20 °C ± 0.01 °C (compared to water at 4 °C) is D420 = 1.331.
