Key result
Auto-ignition temperature:
275 °C
Atm. press.:
1 013.25 hPa

Three replicate main tests were performed under atmospheric pressure.

The following lowest values were recorded:

Experiment Value (°C)

Drops

used
1 277 4
2 289 4
3 283 20

The lowest value of the auto ignition temperature was 277 °C. This value was determined using 4 drops test item. The auto ignition temperature (result of determination) is the lowest value from the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature was determined to be 275 °C.

The three lowest values of the main study lay within a range of 10 K as required for auto ignition temperatures (below 300 °C). Thus, the validity criterion which is demanded in the DIN standard was fulfilled.

Conclusions:
The auto-ignition temperature of the test item (rounded down to a whole multiple of 5 °C) was determined to be 275 °C.
Executive summary:

A study was performed according to Regulation (EC) No 440/2008, Method A.15 and DIN 51794 in order to determine the auto-ignition temperature of the test item. The lowest value of the auto-ignition temperature was 277 °C. This value was determined using 4 drops test item. The auto-ignition temperature (result of determination) is the lowest value from the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto-ignition temperature was determined to be 275 °C.

The three lowest values of the main study lay within a range of 10 K as required for auto ignition temperatures (below 300 °C). Thus, the validity criterion which is demanded in the DIN standard was fulfilled.

Additional information

A study was performed according to Regulation (EC) No 440/2008, Method A.15 and DIN 51794 in order to determine the auto-ignition temperature of the test item (reference 4.12-1). The lowest value of the auto-ignition temperature was 277 °C. This value was determined using 4 drops test item. The auto-ignition temperature (result of determination) is the lowest value from the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto-ignition temperature was determined to be 275 °C.

The three lowest values of the main study lay within a range of 10 K as required for auto ignition temperatures (below 300 °C). Thus, the validity criterion which is demanded in the DIN standard was fulfilled.
