Applicant's summary and conclusion

Conclusions:
The GLP study was performed according to EU method A.2 without deviations and therefore reliability of Klimisch 1 has been assigned. Boiling point has been determined to be 246°C.
Executive summary:

The boiling point at 246 °C of the test substance was determined in a GLP test according to EU method A.2 using the DSC method. The boiling point was determined with the DSC-method described in ASTM E 472 -86 and DIN 51007:2009. A sample was placed in a crucible from aluminum and closed with a cap with a hole from abaout 0.5 mm. This hole was covered by a ball from 1.5 mm diameter. The substance and a reference crucible were subjected to the same controlled temperature program. The sample was heated at a linear rate of 10K/min from 30°C up to 350°C. The measurement was recorded electronically. The measurement was made twice. The atmospheric pressure at the time of measurement was 1011 hPa. The temperatures were corrected to normal pressure by the Sidney-Young equation.
