Based on results of the main test series, the lowest auto-ignition temperature was 400 °C.

The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 395 °C (EU A.15).

Conclusions:
The test item has an auto-ignition temperature of 395°C at 1000.2 hPa.
Executive summary:

In the current study the auto-ignition temperature of the test item was assessed according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases).

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. 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 395°C at 1000.2 hPa (EU A.15 criterium).

Description of key information

The auto-ignition temperature of the test item was determined according to EU method A.15. The self-ignition temperature was found to be 395°C at 1000.2 hPa.

Key value for chemical safety assessment
