Results and discussion

Relative self-ignition temperature (solids)
Relative self-ignition temperature:
390 °C
Remarks on result:
other:
Remarks:
at atm. press. of ca.1013.0 mBar

Any other information on results incl. tables

An exothermic reaction occurred at 170°C and led to a slow temperature increase to 412°C. The temperature of the test item exceeded 400°C at a corresponding oven temperature of 390°C. In conclusion, the relative self-ignition temperature was 390°C, according to the testing guideline for auto flammability in the sense of the European Commission Regulation (EC) No. 440/2008 (A16).
