Final Result

Using the pycnometer method, a density of 1.2536 ± 0.0005g/cm3at 20 ± 0.4 °Cwas measured.This valueisthe mean of two independent determinations with the maximum error of a single determination.Standard deviation was 0.0084 g/cm3, showing good correlation of the two determinations

Applicant's summary and conclusion

Conclusions:
Using the pycnometer method, a density of 1.2536 ± 0.0005g/cm3 at 20 ± 0.4 °C was measured. This value is the mean of two independent determinations with the maximum error of a single determination.
Standard deviation was 0.0084 g/cm3, showing good correlation of the two determinations.
Executive summary:

The density of the test item was determined with a not-GLP compliant study following the standard guideline OECD TG 109. Using the pycnometer method, a density of 1.2536 ± 0.0005g/cm3 at 20 ± 0.4 °C was measured. This value is the mean of two independent determinations with the maximum error of a single determination.

Standard deviation was 0.0084 g/cm3, showing good correlation of the two determinations.
