EC number: 907-578-1 | CAS number: -
Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- yes
- Remarks:
- A 50mm3 (instead of 20 mm3) mesh cube was employed to keep sufficient mass of sample present to allow sustained ignition.
- GLP compliance:
- yes
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Lot/batch No.of test material: A0076
- Expiration date of the lot/batch: 2021
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient (15±10°C), protected from light
TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: The test substance was tested as received - Key result
- Relative self-ignition temperature:
- 206 °C
- Remarks on result:
- other: The temperature of self ignition was extrapolated from the temperature/time curve.
- Conclusions:
- The self ignition temperature of the test item was determined to be 206°C.
- Executive summary:
The self ignition temperature of the reaction mass of amines, hydrogenated tallow alkyl and azelaic acid and lithium hydroxide was determined according to EU A.16. A steel mesh cube (5 x 5 x 5 cm, #300 mesh / 0.045mm aperture) was filled with the test item and placed in an oven. The temperatures of the oven and sample were continuously recorded while the temperature of the oven was increased to the melting point of the substance at a rate of 0.5°C/min. The self ignition temperature of the test item was determined to be 206°C. This study is considered to be reliable without restrictions (Klimisch 1) as it was conducted according to a guideline method. Although the mesh cube was larger than recommended by guideline (50mm3 instead of 20mm3), it was required to keep sufficient mass of sample present to allow sustained ignition.
