Preliminary test

The lowest auto-ignition temperature was found between 567 °C and 568 °C (corrected values) with a volume of 190 μL.

The main test will be conducted using this volume.

Conclusion

The auto-ignition temperature of the test item was 567 °C ± 3 °C (corrected temperature) at 985 kPa.

Conclusions:
No auto-ignition temperature was observed up to 567 °C at 978 hPa in a reliable study conducted according to an appropriate test protocol.
