Results and discussion

Relative self-ignition temperature (solids)
Key result
Remarks on result:
no self ignition observed under the test conditions
Remarks:
(up to 400°C)

Any other information on results incl. tables

At the start of the test, the test item was a white powder.

At the end of the test, the cube was full of white powder. The test item remained stable.

The temperature of the test item sample followed the temperature of the oven up to the highest oven temperature reached (400°C).

Similar observations were made in the two assays.

Applicant's summary and conclusion

Conclusions:
The self-ignition temperature of the test item was investigated according to the EU A.16 method in compliance with GLP. No self-ignition temperature was observed up to 400°C (corrected value). The temperature of the test item sample followed the temperature of the oven.
