Applicant's summary and conclusion

Conclusions:
The determination of the boiling point was performed in accordance with Regulation (EC) No 440/2008, method A.2 ''Boiling Temperature'' (May 2008) and OECD Guideline No 103 ''Boiling Point'' (July 1995).
The boiling range of DELTA-2-CARENE (batch FAB-21092017) should be stated at (235.9 - 246.7 +/- 0.1)°C or (509.1 - 519.9 +/- 0.1)K at 1013.25 hPa.
Executive summary:

The purpose of the study was to determine the boiling point of substance DELTA-2 -CARENE.

The determination of the boiling point was performed in accordance with Regulation (EC) No 440/2008, method A.2 ''Boiling Temperature'' (May 2008) and OECD Guideline No 103 “Boiling Point” (July 1995).

The boiling range of DELTA-2 -CARENE (batch FAB-21092017) should be stated at (235.9 - 246.7 +/- 0.1)°C or (509.1 - 519.9 +/- 0.1)K at 1013.25 hPa.
