Remarks:
at atm. press. of ca.1013.0 hPa

Any other information on results incl. tables

Using a linear increase in temperature of about 0.5 °C/min, the test item showed exothermic reaction with a maximum about 640 °C after the oven obtained 400°C. At the end of the measurement a red fine glowing powder remained in the sample tube. On the surface the residue was powdery while underneath the substance was black and carbonized.

A self-ignition temperature of >400°C has been entered although the test substance is not auto-flammable according to the criteria as described in the guideline.

Applicant's summary and conclusion

Conclusions:
The test item is not auto-flammable, according to the criteria as described in the guideline.
Executive summary:

A test for the relative self-ignition temperature according to EU testing guideline showed that the test substance is not auto-flammable according to the criteria of the guideline. The relative self-ignition temperature is given as >400°C.
