Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- November 30, 2011 - December 01 , 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- no
- Key result
- Relative self-ignition temperature:
- 372 °C
- Conclusions:
- The relative self-ignition temperature was determined to be 372 °C.
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 Part A A.16 to determine the relative self-ignition temperature of the test substance. The test item showed a strong endothermic effect from the start of the measurement to 200 °C. Above 280 °C the temperature of the test item showed an exothermic effect leading to a maximum temperature of 425 °C. The basket was partially emptied at the end of the test (most likely during the strong endothermic effect at the beginning of the measurement). This strong endothermic effect was most probably caused by the evaporation of the water within the test item. The temperature of the test item exceeded 400 °C at a corresponding oven temperature of 372 °C.
