- 101 kPa
- Remarks on result:
- other: +/- 5 °C
- Conclusions:
- The test item has been determined to have an auto-ignition temperature of 386 ± 5 °C.
- Executive summary:
The auto-ignition temperature of the test item was determined using a Carbolite flask heater and a procedure compatible to EU Method A.15. The test flask was heated in a flask heater. Aliquots of test item (tested as received) dropped into the flask which was observed for signs of ignition over a 300 second period. This procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which ignition, if any, occurred within 300 seconds of insertion, was determined. The test item has been determined to have an auto-ignition temperature of 386 ± 5 °C.
