- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Relative self-ignition temperature:
- > 405 °C
- Remarks on result:
- other: No self-ignition temperature was observed up to the maximum test temperature of 405°C.
- Remarks:
- at atm. press. of 1.0 atm
- Conclusions:
- Based on the results of the read across study, no self-ignition temperature is expected for the test substance.
- Executive summary:
A study was conducted to determine the self-ignition temperature of the read across substance, Coco TMAC (99.6% active), according to EU Method A.16 and in compliance with GLP. 8 cm3 (2.6 g) of the read across substance was placed in an oven at 23°C. The temperature-time curve relating to condition in the centre of the sample was recorded while the temperature of the oven was increased to 400°C at a rate of 0.5°C/minute. Under the study conditions, no self-ignition temperature was observed up to the maximum temperature of 405°C (Smeykal, 2008). Based on the results of the read across study, a similar absence of self-ignition is expected for the test substance.
Reference
The test substance showed a small exothermic reaction in the temperature range of 175 - 230°C and no further exothermal reaction of the test substance was observed up to a maximum temperature of 405°C.
Two DSC measurements in closed glass crucibles with the test substance showed endothermic effects in the temperature range 35 - 80°C, 225 - 270°C (double peak) and 305 - 320°C and no exothermal effect up to the maximum test temperature of 400°C.
Description of key information
The self-ignition temperature of the read across substance, Coco TMAC was determined according to EU Method A.16 (Smeykal, 2008). Key value for chemical safety assessment
Additional information
No self-ignition up to 405°C
