Applicant's summary and conclusion

Conclusions:
The density of ADDUKT TI 65-MXDA was calculated as 1.0595 ± 0.0468 g/cm3 at 21.8°C,
which is the mean of two values. Precision of the value is given as maximal error of determination.
The standard deviation of the two values is much lower than the maximal error, indicating
that the error of the determination was lower than the calculated value. Correspondence of
the values is very good. Therefore, the study is considered valid.
One further experiment was performed, using H2O with surfactant as replacement liquid.
Air bubbles could be detected at the test item’s surface; the bubbles could not be removed
using ultrasonic. therefore, this experiment was invalidated and its data is not stated in this
report. The raw data is kept under GLP conditions together with the other raw data of the
study.
Executive summary:

Using the pycnometer method, a density of

1.0595 ± 0.0468 g/cm3

was measured, this value being the mean of two independent determinations with the

maximum error of determination.

Standard deviation was 0.0028 g/cm3, showing very good correlation of the two determinations.
