Main test

Taking into account the results obtained during the preliminary assay, no main test was performed.

 

Conclusion

Only a preliminary test was performed: No auto-ignition temperature was observed up to 601 °C (corrected value).

Conclusions:
No auto-ignition temperature was observed up to 601 °C at 980 hPa in a reliable study conducted according to an appropriate test protocol.

Description of key information
