Auto-ignition temperature test substance

The tables below list the results of the pre-determination and the different test series. A negative sign (-) means no ignition and a positive sign (+) means ignition. In case of ignition the time in seconds between injection and ignition is mentioned between brackets. The bold temperature values in the main determination table are the minimum ignition temperatures of the different test series.
