Key result

Auto-ignition temperature:

460 °C

Atm. press.:

1 013.25 hPa

Preliminary test

The lowest temperature at which an ignition occurs was determined to be 410 °C.

Main test

The lowest ignition temperature was determined to be 409 °C at 1012.2 – 1012.3 hPa in the first test series, 409 °C at 1012.4 hPa in the second test series and 413 °C at 1012.4 hPa. Thus, according to the guideline criteria the auto-ignition temperature rounded down to a whole multiple of 5 °C was determined to be 405 °C.

Conclusions:

The auto-ignition temperature was determined to be 405 °C at 1012.2 - 1012.4 hPa.

Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 Part A A.15 to determine the auto-ignition temperature of the test substance. In a preliminary test the approximately auto-ignition temperature were 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 5 K until no ignition was observed. The test was repeated with slighter temperature steps to determine the auto-ignition temperature more accurate. According to criteria as laid down in DIN 51794 the auto-ignition temperature is the lowest value out of three experiments rounded down to a whole multiple of 5 °C. Therefore the auto-ignition temperature was stated to be 405 °C. All three values lay within a range of 20 K. No observations were made which might cause doubts concerning the validity of the study outcome. Thus, the validation criteria were fulfilled.
