Administrative data
- Endpoint:
- stability: thermal, sunlight, metals, other
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- other: The test method is commonly used in other than REACH Regulation context for the thermal stability characterization and it can be considered as scientifically acceptable. Nevertheless, only the test sheet is available.

Applicant's summary and conclusion
- Conclusions:
- The test substance decomposes at 255 °C, under air conditions. The exothermic reaction was judjed as air-independent and in air-flow conditions it resulted stronger than without active O2-supply. Start of endothermic reaction was recorded at 70 °C, observing the evaporation of H2O solvent.
- Executive summary:
The air dependence of the thermal decomposition was determined using the RADEX test dynamically with air flush.
The start of exothermic reaction under open air conditions was recorded 255 °C (decomposition energy greater than 24 J/g), while under closed air conditions the start of exothermic reaction was recorded at 240 °C (decomposition evergy grater than 230 J/g). The exothermic reaction was judjed as air-independent and in air-flow conditions it resulted stronger than without active O2-supply. Start of endothermic reaction was recorded at 70 °C, observing the evaporation of H2O solvent.
