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:
- no
- Principles of method if other than guideline:
- No sample preparation was necessary. The cube was filled with the test item. The cube was mounted in the oven at 22.1 °C with a thermo element placed at the centre of the cube. Simultaneously the temperature of the oven was measured. The temperatures of the oven and the sample were measured every 5 minutes while the temperature of the oven was increased to 285 °C (the melting point of L-Isoleucine). Ignition of the test item is automatically detected when a very sharp temperature rise above the oven temperature is detected inside the sample cube.
- GLP compliance:
- yes

- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material:

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature (20+/-5°C), away from light and humidity. - Relative self-ignition temperature:
- > 475 °C
- Remarks on result:
- other: The substance is not autoflammable.
- Conclusions:
- L-Isoleucine is not autoflammable under the conditions of the current test.
- Executive summary:
In the current study the auto-flammability of L-Isoleucine was determined according to the EU A.16 method. The study is GLP. The test item was placed into a stainless steel cube and heated from room temperature to an oven temperature of 285 °C.
No sharp increase in the temperature of the sample over 400 °C in comparison to that of the oven could be detected.
After the test no residue of the test item remained.
The test item L-Isoleucine should be considered as not auto-flammable under the current conditions.
