Results:

The requirements for repeatability of the DIN standard are stated as follows: Three lowest values of the main test have to lie within a range of 5 K (if auto ignition temperature is below 300 °C).

The following lowest values were recorded:

The lowest value of the auto ignition temperature is 260 °C. This value was determined using 9 drops test item. The test item showed auto ignition after 135 seconds.

The auto ignition temperature (result of determination) is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 260 °C.

Conclusions:
The lowest value of the auto ignition temperature is 260 °C. This value was determined using 9 drops test item. The test item showed auto ignition after 135 seconds.
Executive summary:

The study was performed in order to determine the auto-ignition temperature of test item according to EU A.15 guideline.

The lowest value of the auto ignition temperature is 260 °C. This value was determined using 9 drops test item. The test item showed auto ignition after 135 seconds.

The auto ignition temperature (result of determination) is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 260 °C.

Description of key information

The auto-ignition temperature of test item was determined to be 260°C.

No particular hazard is anticipated in normal conditions of storage.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
260 °C

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.

This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
