Description of key information

392°C at 99 kPa (EU A.15)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
392 °C

Additional information

The difference between the pressure measured during the test and the standard pressure is regarded as negligible.
