Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 29 Aug. to 03 Sept. 2007
- 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. The substance is adequately characterised with its purity. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- Directive 92/69/EEC
- Qualifier:
- according to guideline
- Guideline:
- IEC 60079-4 (Electrical apparatus for explosive gas atmospheres. Part 4: Method of test for ignition temperature)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
- Version / remarks:
- May 2003
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Certificate from 2007-05-16
- Key result
- Auto-ignition temperature:
- 240 °C
- Atm. press.:
- >= 1 010.9 - <= 1 017.3 hPa
- Conclusions:
- Not relevant for classification, but useful for safe handling.
- Executive summary:
The auto-ignition temperature of the test substance was measured, under GLP, according to EU A.15 / DIN 51794 / IEC 60079-4 guidelines. Three main measurements were performed, varying the sample volume. The lowest value was retained, and rounded down to the nearest 5°C, resulting in an auto-ignition temperature of 240°C.
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 30 May - 28 June 2005
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. However, details were limited, and the test item identification is incomplete (unspecified cis-trans isomery, therefore identified under the generic CAS 17129-06-5). Therefore validation applies with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- Directive 92/69/EEC
- Qualifier:
- according to guideline
- Guideline:
- IEC 60079-4 (Electrical apparatus for explosive gas atmospheres. Part 4: Method of test for ignition temperature)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Certificate from 2004-12-22
- Auto-ignition temperature:
- 242 °C
- Atm. press.:
- 102.3 kPa
- Executive summary:
The auto-ignition temperature of the test substance was measured, under GLP, according to EU A.15 / IEC 60079-4 guidelines. The temperature and the sample volume were varied until the lowest auto-ignition temperature was recorded, i.e. 242°C.

Preliminary test
The estimated auto-ignition temperature of the test substance was 280°C.
Main study
Test | Volume [µl] | Auto-ignition temperature [°C] | Time lag [s] | Colour of flame |
Test 1 | 70 | 277 | 16 | orange |
350 | 242 | 46 | orange | |
750 | 288 | 111 | orange | |
Test 2 | 100 | 266 | 33 | orange |
600 | 253 | 33 | orange | |
900 | 285 | 97 | orange | |
Test 3 | 80 | 276 | 23 | orange |
150 | 255 | 33 | orange | |
800 | 284 | 81 | orange |
The lowest measured auto-ignition temperature is 242°C. This temperature was rounded down to the nearest 5 °C, resulting in the final auto-ignition temperature of 240°C.
Amount of test substance: 0.19 mL
Atmospheric pressure: 102.3 kPa
Ambient temperature: 23°C
Time to ignition: 66 s
Self-ignition temperature: 242°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:
- 240 °C
Additional information
Two experimental studies are available, both conducted according to EU/(DIN)/IEC guideline and GLP:
- The measurement presented in Notox 2007 report, was considered as fully reliable. The result is retained as key data.
- The measurement in TNO 2005 report, was assigned lower reliability, due to incomplete test item identification (i.e. unspecified cis-trans isomery) and lack of experimental details, so included as supporting data.
The results (240 and 242°C, respectively) are fully consistent, considering the observed values can be rounded down to the nearest 5°C, or not, depending on the reference guideline.
This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
