Room temperature:20°C
Atmospheric pressure: 101.63 to 102.19 kPaConclusion
The test item has been determined to have an auto-ignition temperature of 260 ± 5°C.
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2013
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Although this study was conducted in accordance with international guidelines, it was not conducted according to the principles of GLP.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- GLP compliance:
- no
- Auto-ignition temperature:
- 250 °C
- Atm. press.:
- 1 016 hPa
- Remarks on result:
- other:
- Conclusions:
- The auto ignition temperature of the substance is 250°C
- Executive summary:
The first principal test will not be used for the assessment because the lowest auto-ignition temperature deviates more than 10 K from the lowest auto-ignition temperature in the other principal tests. The lowest auto-ignition temperature of the test item was determined to be 252 °C in the main test. Due to safety reasons and according to the guidelines the lowest measured temperature at which an ignition was observed was rounded to the next lower number divisible by 5, giving a value of 250 °C.

- 260 °C
Additional information
The overall endpoint determination for auto-ignition temperature was conducted by heating aliquots of the test item in a flask and observing for any ignition.
