Preliminary Test

An approximate value of the ignition temperature of the test item was firstly determined by the preliminary test. Table 1 gives the result of the preliminary test. An ignition is denoted as “+" and no ignition is denoted as "-". 5 drops were put into the Erlenmeyer flask at each temperature.

According to observations in the test series, the auto-ignition temperature rounded down with an accuracy of 5 °C was determined to be 260 °C.

Conclusions:
The auto-ignition temperature was determined to be 260 ± 5 °C at 99.16 to 100.12 kPa atmospheric pressure.
Executive summary:

The auto-ignition temperature was determined using EU Method A.15 and DIN 51794 (2003). The auto-ignition temperature is the lowest temperature at which the test item will ignite when mixed with air under the conditions defined in the test method. Atmospheric pressure was 99.16 to 100.12 kPa during the course of the study. The auto-ignition temperature was determined to be 260 ± 5 °C.
