EC number: 947-520-2 | 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 July 2016 to May 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- yes
- Remarks:
- the maximal temperature tested was 554 °C instead of 600 °C due to an oven disfunction. This deviation was not considered to have affected the quality or the interpretation of the results obtained.
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Batch No.of test material: 24/02/2016
- Expiration date of the lot/batch: July 2021
- Purity test date: July 2016
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: In darkness at room temperature - Key result
- Auto-ignition temperature:
- > 554 °C
- Atm. press.:
- ca. 1 013.25 hPa
- Conclusions:
- No auto-ignition temperature was observed up to 554 °C (corrected value).
- Executive summary:
The determination of the auto-ignition temperature of test item was performed according to the Commission Regulation (EC) N° 440/2008 A.15 method.
The test is repeated at different temperatures (from about 100°C to about 600°C) until the minimum value of the ignition temperature was observed
No auto-ignition temperature was observed up to 554 °C (corrected value).

Taking into account the results obtained in the preliminary assay, no main test was performed.
Description of key information
One reliable study is available for this endpoint. In this study, the auto-ignition temperature of the test item was determined accordingly the EC A.15 method. The study was GLP compliant.
As a result, only a preliminary test was performed since no auto-ignition temperature was observed up to 554 °C.
Key value for chemical safety assessment
