guideline study
Qualifier:
according to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
no
GLP compliance:
no
Key result
Relative self-ignition temperature:
> 400 °C
Remarks on result:
no self ignition observed under the test conditions

The test was carried out twice.

 

Run 1: No exothermic activity in the sample.

Run 2: No exothermic activity in the sample.

Conclusions:
Following a relative self-ignition temperature for solids test, calcium titanate was shown not to undergo any exothermic reaction up to 400°C, nor to possess a relative self-ignition temperature below 400°C. Classification as an auto flammable substance is not required.
Executive summary:

An experiment was performed to determine the relative self-ignition temperature (auto flammability) of solid calcium titanate. The moisture content of the sample was 1.05 % m/m. The temperature at which the sample achieves 400°C by self-heating is termed the self-ignition temperature. The experiment was performed in duplicate. Calcium titanate did not undergo any exothermic reaction up to 400°C and did not possess a relative self-ignition temperature below 400°C. The relative self-ignition temperature for calcium titanate is >400°C. It has been concluded that classification as an auto flammable substance is not needed and that further study is not required.
