Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- GLP compliance:
- yes (incl. QA statement)
- Auto-ignition temperature:
- 335 °C
- Atm. press.:
- ca. 1 007 - ca. 1 013 hPa
- Conclusions:
- The auto-ignition temperature of the test item was determined as 335 °C at atmospheric pressure.
- Executive summary:
The auto-ignition temperature of the test item was determined according to the auto-ignition test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.15.
In the main test, the ignition at the preliminary test temperature is repeated, the temperature is decreased by 5 °C and the test is repeated. This procedure is repeated until no ignition was observed. Subsequently the amount of test item added to the apparatus is varied at the same temperature. If an ignition occurs during the variation of the amount of test item, the
temperature is decreased again by 5 °C and the procedure started again. The test is continued by choosing the lowest temperature found in the previous step where an ignition occurred. The test temperature is lowered in intervals of approximately 2 °C till no ignition occurs within 5 min after introducing the sample amount of substance as found before. At that temperature where no ignition occurred within 5 min the amount of the test substance is varied stepwise until ignition occurs. The auto-ignition temperature of the test item was determined as 335 °C at atmospheric pressure.

Results from the test series
Main test series | Auto-ignition temperature [°C] |
1st main test (5 K steps) | 347 |
1st main test (2 K steps) |
345 |
2nd main test (2 K steps) |
341 |
3rd main test (2 K steps) |
339 |
The lowest auto-ignition temperature of the test item was determined to be 339 °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 335°C.
