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
Remarks:
According to EU Method A.16. GLP study.
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Key result
Relative self-ignition temperature:
> 400 °C

The test item did not ignite until the temperature of 400 °C.

Conclusions:
The substance is not self-ignitable.
Executive summary:

The study was performed in accordance with EU Method A.16 and GLP standards. A certain volume of the substance under test is placed in an oven at room temperature; the temperature/time curve relating to condition in the centre of the sample is recorded while the temperature of the oven is increased to 400 ºC, or to the melting point if lower, at a rate of 0.5º C/min. The substance did not ignite until the temperature of 400ºC, so the substance was determined to be not self-ignitable.

Description of key information

Key study: EU Method A.16. GLP study. The substance did not ignited up to 400 ºC, therefore the subtance was considered to be non self-ignitable.

Key value for chemical safety assessment

Additional information

Key study: The study was performed in accordance with EU Method A.16 under GLP conditions. A defined volume of the theobromine was placed in an oven at room temperature; the temperature/time curve relating to condition in the centre of the sample is recorded while the temperature of the oven is increased to 400 ºC, or to the melting point if lower, at a rate of 0.5º C/min. The substance did not ignite until the temperature of 400ºC, so the substance was determined to be not self-ignitable.
