- Key result
- Auto-ignition temperature:
- 415 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- The test item has an auto-ignition temperature of 415 °C.
- Executive summary:
According to Regulation EC No. 440/2008 method A.15. and DIN 51794 the auto-ignition temperature is regarded as the lowest temperature rounded down to the nearest multiple of 5 °C at which an ignition is observed in any of the main tests. The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 415 °C.
According to DIN EN 14522 the auto-ignition temperature is regarded as the lowest temperature reduced by 1.5 % and rounded to the nearest integer temperature at which an ignition is observed in any of the main tests.The auto-ignition temperature reduced by 1.5 % and rounded to the nearest integer temperature was determined as 409 °C.
