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.
