Individual Results

Preliminary test: The lowest auto-ignition temperature was determined to be 423 °C.

Main test: The following table shows the results of the three principal tests. Temperatures, where auto-ignition (+) was detected and where not (-). The amount of test item tested at each measurement is indicated as numbers of drops.
