- Conclusions:
- The auto-ignition temperature of the test item was determined to be 235 °C.
- Executive summary:
An experimental study was conducted to determine the flash point of the test item according to Regulation EC No. 440/2008 Method A.15. and DIN 51794. The experiment was performed in a semi-automated (ZT1) and fully automated apparatus (ZT2). The lowest temperature of ignition rounded down to the nearest multiple of 5 °C was determined to be 235 °C.
