Applicant's summary and conclusion

Conclusions:

The melting point temperature of the test item is relatively low (28 - 33 °C provided
by the study monitor); as a consequence, some difficulties of homogeneity happened during
the test.
The mean relative density of the test item was D) = 0.939 ± 0.001 at 20.6 °C.

Executive summary:

In compliance with

Regulation (EC) No. 1907/2006, Council Regulation (EC) No. 440/2008

EC A.3. method (2008) and OECD Guideline No. 109 (2012)

The mean relative density of the test item was D = 0.939 ± 0.001 at 20.6 °C.
