Reference
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 and lot/batch No.of test material:
- Expiration date of the lot/batch: 140147K06B

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.

 

Description of key information

L-Isoleucine is not autoflammable.
