- Key result
- Auto-ignition temperature:
- 255 °C
- Atm. press.:
- >= 992.1 - <= 1 004.2 hPa
- Conclusions:
- The auto-ignition temperature was determined to be 255 °C under the test conditions.
- Executive summary:
A study according to Regulation (EC) No. 440/2008 Method A.15 and DIN 51794 was conducted to determine the relative auto-ignition temperature of the test item. The auto-ignition temperature was determined using an automatic test system according to DIN 51794. It measures the lowest temperature at which auto-ignition occurs. The main test was performed in triplicate. The auto-ignition temperature is the lowest of the measured values rounded down to the nearest multiple of 5 °C. The auto-ignition temperature under the test conditions was determined to be 255 °C.
Reference
Three replicate main tests were performed under atmospheric pressure (992.1 – 1004.2 hPa). The following lowest values were recorded:
