Results and discussion
Any other information on results incl. tables
No endothermic or exothermic effect was recorded for the test substance sample between 20°C and the melting temperature of the test substance (i.e. 37.0°C).
A first small exothermic reaction started at an oven temperature of about 213°C. The test substance temperature increased (by self-heating) and was at the most 23.5°C higher than the oven temperature. The reaction ended at approximately 274°C. A second exothermic reaction started at an oven temperature of about 311°C. The test substance temperature increased (by self-heating) and was at the most 36.2°C higher than the oven temperature. The reaction ended at approximately 365°C. These exothermic effects are probably due to decomposition/reaction but are of no relevance for the self-ignition study.
At an oven temperature of approximately 397°C, just before the final test temperature had been reached, the temperature of the test substance was 400°C. Since this temperature reading is not the result of a sharp temperature rise but a prolongation of the second exothermic reaction, this effect is not ascribed to self-ignition by self-heating.
However, a third exothermic reaction started after the test was finished; the test substance temperature increased to 539°C (by self-heating). Considering the sharp temperature rise, this may be considered as self-ignition of the test substance. But, since this effect was observed after the final oven temperature had been reached, the test substance is not considered to be self-ignitable.
After the experiment, there was a small amount of grey residue in the cube and a small amount grey residue had been collected in the container placed below the cube. The colour had changed from blue into grey. This change of colour is an indication that decomposition had occurred.
Applicant's summary and conclusion
- Conclusions:
- The test substance is not self-ignitable.
