Key result
Auto-ignition temperature:
465 °C
Atm. press.:
>= 990.3 - <= 997.5 hPa

Preliminary test:

In the preliminary test, an ignition was observed at 469 °C. The atmospheric pressure was noted to be 993.1 – 997.9 hPa.

Main test:

Based on results of the main test series, the lowest auto-ignition temperature was 467 °C.

Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 465 °C.

Conclusions:
The auto-ignition temperature of the test substance was determined to be 465 °C.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 Part A.15, DIN 14522 (2005) and DIN 51794 (2003) to determine the auto-ignition temperature of the test substance. In a preliminary test the approximate auto-ignition temperature was determined. For the main test three test series were conducted. The temperature determined in the preliminary test was used as starting point for the main test. The temperature was decreased by 3 - 4 K until no ignition was observed. According to the criteria laid down in Regulation EC No. 440/2008 method A.15 and DIN 51794, the auto-ignition temperature is the lowest value rounded down to a whole multiple of 5 °C. Therefore, the auto-ignition temperature was determined to be 465 °C at 990.3 - 997.5 hPa.
