Materials and methods

Test guideline

Qualifier:

no guideline available

Guideline:

other: the Standard Operating Procedures in use at DEFITRACES

Principles of method if other than guideline:

The test item sample and reference material are both maintained at the temperature
predetermined by the program even during a thermal event in the sample. The amount of
energy which has to be supplied to the sample to maintain zero temperature differential
between the test item sample and the reference material is the experimental parameter
displayed as the ordinate of the thermal analysis curve. The rate of energy absorption by the
sample is proportional to the specific heat of the sample.
Any transition accompanied by a change in specific heat produces a discontinuity in
the power signal.

GLP compliance:

yes (incl. QA statement)

Type of method:

differential scanning calorimetry

Results and discussion

Boiling point

Decomposition:

yes

Decomp. temp.:

>= 350 - <= 450 °C

Applicant's summary and conclusion

Conclusions:

The temperature of decomposition was situated between about 350 and 450 °C

Executive summary:

During the assays with the steel crucible hermetically closed, only one endothermic peak was observed at 110.8 °C, during the first pha se (melting point). During the second phase, neither endothermic nor exothermic peak was observed up to 500 °C under our experimental conditions. A degradation of the test item probably occurred. So as to confirm this degradation, another assay was performed with an aluminium crucible closed but not hermetically. In this assay, it was showed that a degradation was observed between 350 and 450 °C represented by a se ries of little peaks. The temperature of decomposition was situated between about 350 and 450 °C
