The measured lowest ignition temperatures of the main test are < 300°C and do not differ by more than 10°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 reduced to the next lower multiple of 5°C.
| Test 1 | Test 2 | Test 3 |
Lowest ignition temperatures (°C) | 251 | 250 | 250 |
Auto-ignition temperature (°C) | 250 | ||
The auto-ignition temperature of the test item was determined according to EU test method A. 15 (Council Regulation (EC) NO. 440/2008, Official Journal L 142/1 2008) and DIN 51 794 (2003).
Auto-ignition temperature (1009 hPa): 250°C
