Conclusions:

Under the conditions of this study, the auto ignition temperature of the test material was 364 ± 4 °C, at the atmospheric pressure of 99.2 kPa.

Executive summary:

The auto ignition temperature of the test material was investigated in accordance with the standardised guidelines EU Method A.15 and ASTM-E 659-78, under GLP conditions.

The required volume of test material was injected as droplets with a pipette into the centre of the flask which was contained within an oven. The time when any flash or flame was observed was read from the chart trace, or the test was run for approximately five minutes. The procedure was repeated at different temperatures and with different sample volumes until the minimum value of the ignition temperature was obtained. The tests were made in appropriate temperature steps until the lowest temperature at which ignition occurs had been determined. This is the auto-ignition temperature. The atmospheric pressure at the time of testing was recorded.

Under the conditions of this study, the auto ignition temperature of the test material was 364 ± 4 °C, at the atmospheric pressure of 99.2 kPa.
