Any other information on results incl. tables

In a duplicate experiment the density of DC-5067 was determined to be 0.953 g/cm³ (0.953 kg/m³), using a 10 ml pycnometer. Temperature of measurements was 20.0°C. Individual measurements and calculations are shown in Table 2. The D₄²⁰ is 0.953.

Applicant's summary and conclusion

Conclusions:

The density of the liquid test substance DC-5067 was determined to be 0.953 g/cm3 (0.953*10exp3 kg/m3).

Executive summary:

The determination of the density (liquid) was based on the EEC-Directive A.3 "Relative density" (1984) and on the OECD Guideline no. 109 "Density of liquids and solids" (1981). The density of the liquid test substance DC-5067 was determined to be 0.953 g/cm³ (0.953*10³ kg/m³), using a glass pycnometer with a nominal volume of 10 ml . Temperature of measurement was 20.0°C. D₄²⁰ is 0.953.
