EC number: 947-269-9 | 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:
- 25-28 May 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- DIN EN 14522, Method P (Determination of the auto ignition temperature of gases and vapours)
- Version / remarks:
- 2005
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 4,5 and 6 July 2016/ Signed on 10 January 2017
- Key result
- Auto-ignition temperature:
- >= 493 °C
- Atm. press.:
- >= 974 - <= 975 hPa
- Conclusions:
- Four trials were conducted. In the fourth one, the preselected auto-ignition temperature was set to 550°C anew and the test stopped at 596.2°C (sample temperature) because the furnace security temperature (600°C) was reached. However, a flash was detected at 599°C (sample temperature) just before the apparatus shutdown.
In the same time visual observation was made and weak inflammations were observed by the technician at each injections from 493.6°C (sample temperature) but were not detected by the apparatus. - Executive summary:
The study was performed in order to determine the auto-ignition temperature of test item according to EU A.15 guideline.
Weak inflammations were observed by the technician from 493.6°C (sample temperature) but were not detected by the apparatus. The auto-ignition temperature of test substance was stated as >= 493°C.
This parameter/method is not relevant for classification, however the information is useful regarding potential additional fire hazard. No particular hazard is anticipated in normal conditions of storage.
Reference
Four trials were conducted.
In the first one, the preselected auto-ignition temperature was set to 150°C but no ignition occurred and the test stopped automatically.
In the second one, the preselected auto-ignition temperature was set to 350°C but no ignition occurred and the test stopped automatically.
In the third one, the preselected auto-ignition temperature was set to 550°C but the test stopped at 583.1 °C (sample temperature) due to an undetermined error.
In the fourth one, the preselected auto-ignition temperature was set to 550°C anew and the test stopped at 596.2°C (sample temperature) because the furnace security temperature (600°C) was reached. However, a flash was detected at 599°C (sample temperature) just before the apparatus shutdown.
In the same time, visual observation was made by the technician.
At 469°C, no flame was observed by the technician or detected in the Erlenmeyer flask.
Then, weak inflammations were observed by the technician at each injection from 493.6°C (sample temperature) but were not detected by the apparatus.
The atmospheric pressure was 975.0 hPa at the beginning of the test and 974.0 hPa at the end of the test.
Description of key information
The auto-ignition temperature of test substance was stated as : >= 493.°C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 493 °C
Additional information
A fully reliable experimental study, conducted according to EU A.15 guideline is available.
It is considered as 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
