Applicant's summary and conclusion

Conclusions:
In conclusion, the relative density of ucb 22060 was determined to be
D: = 1.291.
Executive summary:

The determination of the relative density of the test item was performed in accordance with the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.3 “Relative density” and the OECD Guideline for Testing of Chemicals, No. 109, “Density of Liquids and Solids” using a gas comparison pycnometer. The test was performed at a temperature of 20.0°C. The calibration procedure was performed in triplicate. The individual measurements and the results are presented in Table 1. The determination of the relative density of the test item was performed with two independent test item samples each at least measured in triplicate. The individual measurements are summarized in Table 2. The tabulated values in Tables 1 and 2 represent rounded results, which were obtained by calculation using the exact raw data. The density of the test item ucb 22060 was determined to be 1.291 g/ems (= 1.291 “ 10’ kg/m’) at 20.O”C using a gas comparison pycnometer. In conclusion, the relative density of ucb 22060 was determined to be D: = 1.291.
