Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- July 2005
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted to GLP and in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not effect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Auto-ignition temperature:
- >= 251 - <= 261 °C
- Atm. press.:
- >= 100.29 - <= 101.02 kPa
- Conclusions:
- auto-ignition temperature: 256 ± 5°C (at 100.29 to 101.02 kPa)
- Executive summary:
The auto-ignition temperature was determined by heating aliquots of the test material in a flask and observing for any ignition. Testing was conducted using EU Method A15.
The test material 'Naphtha (Fischer-Tropsch), light, C4-10 - branched and linear' has been determined to have an auto-ignition temperature of 256 ± 5°C (at 100.29 to 101.02 kPa).
