EC number: 942-426-8 | 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:
- From 2014-03-07 to 2014-05-07
- 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 was reported. The test substance is considered to be adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- yes
- Remarks:
- time lag before ignition not reported
- Qualifier:
- according to guideline
- Guideline:
- DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
- Version / remarks:
- 2003
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspection 22-23/01/2013, signature 22/03/2013
- Auto-ignition temperature:
- 245 °C
- Atm. press.:
- 1 005 - 1 014.8 hPa
- 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 DIN 51794 method (listed in EU A15 guideline).
The test material was injected into a heated flask, until the lowest temperature at which ignition occurs was determined, for different volumes. Three main test series were performed.
The auto-ignition temperature of the test substance was determined as 245 °C at 1005 -1015 hPa.
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- Based on structural similarity (stereoisomers) and comparing normal flash points, respectively 138°C for the test substance (Firmenich E073-03.2008, 2008), and 142°C for the target substance (Firmenich 102662-DMR, 2008; please refer to IUCLID section 4.11), the target substance is expected to have a similar or slightly higher AIT. Therefore the result of the study will be considered as a limit value for the target substance.
Further information is included in IUCLID Section 13. - Reason / purpose for cross-reference:
- read-across source
- Reason / purpose for cross-reference:
- read-across: supporting information
- Reason / purpose for cross-reference:
- read-across: supporting information
- Key result
- Auto-ignition temperature:
- >= 245 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- This parameter/method is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
(from analogue) No particular hazard is anticipated in normal conditions of storage. - Executive summary:
The auto-ignition temperature of the analogue test substance was measured, under GLP, according to DIN 51794 standard (listed in EU A15 guideline).
The test material was injected into a heated flask, until the lowest temperature at which ignition occurs was determined, for different volumes. Three main test series were performed.
The auto-ignition temperature of the test substance was determined as 245 °C at 1005 -1015 hPa.
A similar, or slightly higher, AIT is anticipated for the target substance.
Referenceopen allclose all
In the preliminary test, the lowest temperature at which an ignition occurred was 262°C.
In the main test series 1, the lowest temperature at which an ignition occurred was 248°C.
In the main test series 2, the lowest temperature at which an ignition occurred was 251°C.
In the main test series 3, the lowest temperature at which an ignition occurred was 246°C.
Atmospheric Pressure: 1005.0 to 1014.8 hPa
According to observations in the main test series, the auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined to be 245 °C.
Detailed determinations are available in the experimental report.
Description of key information
No particular hazard is anticipated in normal conditions of storage. (from analogue)
AIT of target substance expected >= 245°C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 245 °C
Additional information
No data is available on the substance itself.
However, a fully reliable experimental study, conducted according to a recognized DIN/EC method and under GLP, is available on an analogue (reaction mass of stereoisomers, with one common constituent).
Based on compared flash points, minor difference is anticipated with the target substance, the read-across is considered justified for a key study, and the result is retained as key data.
This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
