Applicant's summary and conclusion

Conclusions:

The substance has a relative density of 1.106 g/cm³ at 20.7 °C .

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 20.7 °C.

The calibration procedure was performed in triplicate.

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 density of the test item ZP-TIX 1014 was determined to be 1.106 g/cm³ (= 1.106 kg/m³) at 20.7 °C ± 0.1 °C using a gas comparison pycnometer.
