- yes
- Decomp. temp.:

- Remarks on result:
- other: DSC measurements were performed under inert gas
- Conclusions:
- The determination of the boiling point was determined via DSC (differential scanning calorimetry)
Four determinations were performed resulting in different chromatograms, with very small events.
Observations of decomposition of the substance, were noted during the performance of the Pre-test following SIWOLOBOFF indicated by colour change.
DSC measurements were performed under inert gas; therefore the test item was protected from the environment and may explain why no feasible event occurred.
Therefore including all data the boiling point of Hatcol 3178 can be stated as > 350 °C. - Executive summary:
The determination of the boiling point was determined via DSC (differential scanning calorimetry)
Four determinations were performed resulting in different chromatograms, with very small events.
Throughout the test no boiling point as indicated by a clear endotherm event could be observed.
The detected events cover a range from 0.0957 to 1.0988 mW. The signal noise of the instrument was measured with approx. 3.5 μW (routine maintenance of 08. Dec. 2016). In accordance with the manufacturer, only events which are 3 times bigger than the signal noise are significant. In this case some events are above this limit.
For a better differentiation of the artefacts, a blank measurement (empty aluminium crucible as sample) performed on 12. Jan. 2017 (routine inspection) was taken into account.
Events from 0.0076 to 0.0242 mW were detected.
By comparing the test item measurements with the blank measurement it is apparent that some reaction took place. This is supported by the fact that after three of the four performed measurements the crucible was lighter, which is surely caused through evaporation of the test item.
Observations, which may be the proof of decomposition of the substance, were observed during the performance of the Pre-test following SIWOLOBOFF indicated by colour change.
DSC measurements were performed under inert gas; therefore the test item was protected from the environment this might explain why no feasible event occurred.
Therefore including all data the boiling point of Hatcol 3178 can be stated as > 350 °C.
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.

Security Pre-test for the DSC instrument
The lid of the first crucible was found to be bloated. Discoloration occurred on the side, and at the perforated hole. The findings are indicative of the test item overflowing from the hole after reaching a temperature of 420 °C. After cooling down the weight was recorded as 64.95 mg.
In successive repetition tests the crucible was found visually unchanged after reaching a temperature of 420 °C but discoloration was noted on the side. The weight was recorded as 46.29 mg. After further heating to 600 °C and cooling down the crucible was visually unchanged, and the discoloration on the side had disappeared. The weight was recorded as 45.85 mg.
