Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1995-03-28 to 1995-05-16
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. Purity and isomers composition are available from the notifier. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Qualifier:
- according to guideline
- Guideline:
- IEC 60079-4 (Electrical apparatus for explosive gas atmospheres. Part 4: Method of test for ignition temperature)
- Version / remarks:
- Anon (1987), Electrical apparatus for explosive gas atmospheres. Part 4: Method of test for ignition temperature. IEC Publications 79-4, p1-19.
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP compliance programme (inspected on 31 January 1994 / signed on 16 March 1994)
- Specific details on test material used for the study:
- Storage conditions: metal bottle at room temperature.
- Auto-ignition temperature:
- 294 °C
- Atm. press.:
- >= 100.77 - <= 101.31 kPa
- Remarks on result:
- other: accuracy: +/-5°C
- Conclusions:
- This parameter/method is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
No particular hazard is anticipated in normal conditions of storage. - Executive summary:
The auto-ignition temperature of the test substance was measured under GLP according to IEC 79-4 method (listed in EU A15 guideline).
The test substance was injected into a heated flask, varying the volume, until the lowest temperature at which ignition occurs was determined. The relevant parameters were recorded for the final result.
The auto-ignition temperature of the test substance is 294°C.

Description of key information
No particular hazard is anticipated in normal conditions of storage.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 294 °C
Additional information
A fully reliable experimental study, conducted according to a recognized EC method and under GLP, is available. It is therefore considered as a key study. The result is retained as key data for purpose of CSA.
It should be noted that, due to the multi-isomers nature of the substance tested, this result may refer to the most flammable one. However, as structures are close and b.p. range limited, auto-ignition temperature is not anticipated to vary significantly between components.
This parameter/method is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
