Description of key information

This test substance is auto-ignitable with an auto-ignition temperature of 440°C at 1018.2 - 1020.0 hPa pressure. 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
440 °C

Additional information

The key study for the endpoint (Brekelmans M., 2011) was performed according to the following guidelines and within GLP principles:

-      EU Method A. 15 (Auto-Ignition Temperature (Liquids and Gasses))

-      Deutsches Institute fur Normung (DIN), DIN Guide 51794: "Determining the Ignition Temperature of Petroleum Products¿, May 2003.

-      International Electrotechnical Commission (IEC), IEC standard 79-4: "Electrical Apparatus for Explosive Gas Atmospheres, Part 4, Method of Test for Ignition temperature", 1975.


The lowest temperature at which ignition of the test substance occurred was 442°C. This temperature was rounded off to the nearest multiple of 5°C giving an auto-ignition temperature of the test substance of 440°C.
