Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 2008-10-14 to 2008-11-10
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
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
- Analytical purity: > 95.0%
- Lot/batch No.: 2008-9-16
Relative self-ignition temperature:
> 400 °C
Remarks on result:
no self ignition observed under the test conditions

There was no exothermic reaction consistent with self-ignition of the test substance below 400°C, although there was a small exotherm evident at approximately 240ºC which was likely to be due to decomposition.

Refer to attached background information for a trace of sample and oven temperature recorded against time.

Conclusions:
The test item was found not to self-ignite below 400°C.
Executive summary:

Relative self-ignition temperature for solids is determined in accordance with EU Method A.16.

The test item was found not to self-ignite below 400°C.
