Applicant's summary and conclusion

Conclusions:
Boiling temperature of the test substance, 3,4-Ethylenedioxythiophene, is 228.6oC, i.e. 501.8K. Extended uncertainty of determination is ± 0.5K.
Extended uncertainty was calculated by using a coverage factor of 2.
Executive summary:

The boiling temperatures of the test substance, 3,4-Ethylenedioxythiophene was determined. The Differential Scanning Calorimetry method was used.

The procedures used in the study were in accordance with:

Method A.2 – Boiling Temperature (1.6.6.2 Differential scanning calorimetry), Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008

OECD Test Guideline No.103, Boiling Point, Adopted July 27, 1995

Boiling temperature of the test substance, 3,4-Ethylenedioxythiophene, is 228.6oC, i.e. 501.8K. Extended uncertainty of determination is ± 0.5K.

Extended uncertainty was calculated by using a coverage factor of 2.
