Results
Preliminary test
The lowest self-ignition temperature was determined to be 488 °C.

Main test
Temperatures where self-ignition was detected (+) and those where it was not (-) are shown in Table 1 for the 4 principal tests. The amount of test item tested at each measurement is indicated as number of drops.
