Results and discussion

Relative self-ignition temperature (solids)
Key result
Relative self-ignition temperature:
>= 395 °C
Remarks on result:
other: The relative self-ignition temperature is >395"C, according to the testing guideline for auto- flammability in the sense of the consolidated version of CD 671548lEEC Annex V (CD 92/691EEC), Method A.16. But no sharp temperature increase was observed.

Applicant's summary and conclusion

Conclusions:
The relative self-ignition temperature is >395"C, according to the testing guideline for auto- flammability (solids - determination of relative self-ignition temperature) in the sense of the consolidated version of Council Directive 671548lEEC Annex V (Council Directive 92/691EEC), Method A.16. But no sharp temperature increase was observed.
Executive summary:

The test item temperature exceeded the oven temperature at approximately 300 °C. From this temperature on the temperature of the test item remained permanently slightly (temperature difference: approx. 2 K) above the oven temperature and led to a maximum temperature of 407 °C. No sharp temperature increase was observed.

The temperature of the test item exceeded 400 °C at a corresponding oven temperature of 395 °C.
