Reference
Results in detail:
| test run no. | lowest temperature leading to autoignition (°C) |
quantiy of sample (ml) | ignition delay time (sec) |
| 1 | 373 | 0.09 | 17 |
| 2 | 372 | 0.09 | 17 |
| 3 | 372 | 0.09 | 17 |
Autoignition temperature (corrected)*: 366 °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.
