- Executive summary:
The test has been performed according to EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature without significant deviations.
The test determines the lowest temperature at which a gas/air- or vapour/air-mixture of the flammable test item ignites in contact with a hot surface. For that purpose, the amount of the test item and the temperature of the hot surface are varied. In this way, the lowest temperature rounded down to the nearest multiple of 5 °C is determined at which the test item ignites.
The test item has an auto-ignition temperature of 450°C.
According to DIN EN 13463 -1 the test item has to be assigned to temperature class T1.

2.3 Lowest temperature at which an ignition occured:
Main test series | Lowest temperature of an ignition | Highest temperatures without an ignition | Atmospheric Pressure |
1 | 451 °C | 448°C | 1009.8 - 1014.3 hPa |
2 | 452°C | 450°C | 1013.4 hPa |
3 | 453°C | 451°C | 1013.4 hPa |
Based on the result of the main study the lowest auto-ignition temperature was 451°C
Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5°C was determined as 450°C.
3. Final results: According to the test results, the test item belongs to temperature class T1.
