Conclusions:

The auto-Ignition temperature of the test item was determined to be 450 °C ± 10 °C at 1013.25 hPa.

Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 Part A.15 and DIN 51794 to determine the auto-ignition temperature of the test substance. Four test series were conducted with different sample amounts (100 to 400 µL). Aliquots of the test material (100 to 400 µL) were injected into a flask using a syringe, was observed for signs of ignition over a period of 300 seconds. This procedure was repeated, varying the sample size and the test temperature, until the lowest temperature at which ignition, occurred within 300 seconds of insertion, was determined.

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 determined to be 450 °C at 1013.25 hPa. No observations were made which might cause doubts concerning the validity of the study outcome.

Description of key information
