Any other information on results incl. tables
The starting temperature was approx. 6 °C. The test was stopped after approx. 43 days of storage. A maximum temperature of approx. 162 °C was recorded.
Above approx. 60 °C, a weak exothermic behavior can be observed, the maximum of which reaches 0.21 K/h at 162 °C.
This weak exothermic effect does not have to reflect a real exotherm, but can also be triggered by the (increased) heat transfer conditions changing during the course of the experiment. Both processes can also be superimposed and cannot be separated for evaluation.
The drop in the rate of temperature rise in the range of approx. 145 - 150 °C is due to the selected limit of 150 °C for the ambient temperature. This ambient temperature cut-off criterion was raised again by 15 K (165 °C).
All 3 ACA patterns have a comparable exotherm curve in the temperature range up to approx. 165 °C.
Applicant's summary and conclusion
- Conclusions:
- The substance is considered as stable under the given conditions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
