EC number: 475-900-3 | CAS number: -
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:
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
