The measured lowest ignition temperatures of the main test are > 300 °C and do not differ by more than 20 °C, thus the test is satisfactory.

The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded down to multiples of 5 °C:

Lowest ignition temperatures [°C]:

Test 1: 325;

Test 2: 325;

Test 3: 323;

Auto-ignition temperature: 320 °C

Conclusions:
Auto-ignition temperature (EU method A.15): 320 °C at 1016 hPa
Executive summary:

The auto-ignition temperature of the test item was determined compliant with GLP according to EU test method A.15 [Directive 92/69/EEC, Official Journal L 383 A 1992] and DIN 51 794.

Auto-ignition temperature: (1016 hPa) 320°C

Description of key information
