- Key result
- Auto-ignition temperature:
- 422 °C
- Atm. press.:
- 70 - 77 kPa
- Hot flame autoignition temperature (AIT, °C): 422
- Time lag to autoignition (s): 66
- Barometric pressure (kPa): 100.9
- Test Item quantity (mg): 100
- Relative Humidity (%): 73
- Conclusions:
- auto-ignition temperature: 422°C (at a relative humidity of 70 to 77% and an atmospheric pressure between 99.9 and 100.1 kPa)
- Executive summary:
The auto-ignition temperature was determined by heating aliquots of the test material 'Paraffin waxes (Fischer-Tropsch), isomerization' in a flask and observing for any ignition. Testing was conducted using EU Method A.15
The substance 'Paraffin waxes (Fischer-Tropsch), isomerization' has been determined to have an auto-ignition temperature of 422°C (at a relative humidity of 70 to 77% and an atmospheric pressure between 99.9 and 100.1 kPa)
