Results
test run no. / lowest temperature leading to autoignition [°C] / quantity of sample [ml] / ignition delay time [sec]
1 / 448 / 0.26 / 10
2 / 440 / 0.08 / 30
3 / 443 / 0.08 / 11
Autoignition temperature (corrected)*: 433 °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 T2 or higher.
