Any other information on results incl. tables
An exothermic reaction started at an oven temperature of about 274°C. The test substance temperature increased to 319°C (by self-heating) at an oven temperature of 273°C.
According to the guideline, the test substance is self-ignitable when the temperature of the sample reaches 400°C (by self-heating) before the oven temperature is 400°C. This exothermic effect is probably due to decomposition but is of no relevance for the self-ignition study.
The test substance showed a second exothermic reaction starting at an oven temperature of about 340°C. The test substance temperature increased to >400°C (reaching a maximum of 418°C) at an oven temperature of 341°C. This temperature (341°C) was therefore taken to be the self-ignition temperature for the test substance.
Applicant's summary and conclusion
- Conclusions:
- The test substance is self-ignitable at 341°C.
