Atm. press.:
991.7 - 1 015 hPa
Remarks on result:
other: Rounded down to the nearest multiple of 5 °C

The auto-ignition temperature was rounded down to the nearest multiple of 5°C was determined as 250°C, according to Regulation EC No. 440/2008 and DIN 51794. According to DIN EN 14522, the auto-ignition temperature reduced by 1.5% and rounded to the nearest integer temperature was determined as 250°C.
