* The pressurizing-expansion cycles are performed until 5 subsequent volume measurements have a relative standard deviation (RSD) of ≤ 0.02 %.

The mean density of the test item at 20 °C is 1.116525 g/cm³.

The relative density is D420= 1.12 (calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

Applicant's summary and conclusion

Conclusions:
According to OECD Guideline 109 (1995) and Regulation (EC) No 440/2008 Method A.3., the relative density D420 of the substance is 1.12. (at 20 °C, compared to water at 4 °C).
