Any other information on results incl. tables

The lowest observed self-ignition temperature was reduced with a factor of 1.5 % to cover all measurement related uncertainties (e.g. calibration of the apparatus, volume of the test substance, temperature measurement, etc.).

Measurement   Lowest self ignition temperature [°C]  Sample volume [mL]  Ignition delay [s]
 1  453  0.09  9
 2  456  0.09  9
 3  455 0.09  10

Ignition temperature (corrected) : 446 ° C
