The lowest value of the auto ignition temperature is 445 °C.
This was determined using the 2 drops test item. The test item showed
auto ignition after 10 seconds.
Study Plan Deviations
Because the test item was too viscous, it was brought into the test
vessel with a 2 mL one-way syringe instead of with a pipette.
The start temperature in experiments 2 and 3 of the main study was 10 K above the last ignition temperature instead of 5 K below.
Four thermos elements were used instead of two, to obtain a better detection of the ignition point.
Description of key information
445 °C at 998 hPa (EU Mehtod A.15.)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 445 °C
