Results and discussion

Relative self-ignition temperature (solids)
Remarks on result:
no self ignition observed under the test conditions

Any other information on results incl. tables

No exothermic reaction was observed. The test substance temperature did not exceed 200°C (i.e. a rise of more than 60°C above the oven temperature). Therefore this test was considered negative. No changes were observed in the appearance of the test substance.

Applicant's summary and conclusion

Conclusions:
The test substance is considered 'not self-ignitable'
