Autoignition temperature (corrected)*: 473 °C

* The corrected auto ignition temperature is calculated by subtracting 1.5% of the lowest experimentally observed auto ignition temperature (given in units of °C) in order to take into account all uncertainties (calibration, temperature measuring system, amount of substance, etc.). This value is then rounded to the next 1 K.

Electrical and non-electrical equipment, which may be in contact with explosive mixtures of the test substance and air, has to be of a temperature class T1 or higher.
