- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2000-09-19 to 2000-09-22
- 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))
- Version / remarks:
- EEC Commission Directive 92/69 - A15 method (1992)
- Deviations:

- Key result
- Auto-ignition temperature:
- 437 °C
- Atm. press.:
- 97.4 kPa
- Conclusions:
- The mean auto-ignition temperature of the test item was determined to be 437 °C ± 3 °C.
- Executive summary:
A study was conducted according to Regulation (EC) No 92/69 method A.15 and DIN 51794 to determine the auto-ignition temperature of the test substance. Twelve injections of the test item were made around the auto-ignition point, which was determined in a preliminary test. Five values, in temperature steps of 1 to 3 °C maximum were recorded until the lowest temperature at which ignition occurs was obtained. Therefore, the mean auto-ignition temperature was determined to be 437 °C at 97.4 kPa.
