Presentation of Results

Results of the single determinations with the respective error as well as the mean value and its standard deviation are presented in the following tables:

Results of Single Determinations

Determination	Density in g/cm^3	Error ofDeterm. in g/cm^3
1	1.2596	0.0005
2	1.2477	0.0005

As the third determination confirmed the result of the first determination, the result of the second determination was not used for the calculation of the mean value.

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.
