Description of key information

The auto-ignition temperature of the substance ‘Naphtha (petroleum), steam-cracked, C8-10 aromatic hydrocarbon fraction, alkylated and oligomerised’ (NAF-AO) (see Chap. 1) is > 375 °C at ca. 101 kPa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
375 °C

Additional information

In an auto flammability test following the German test guideline DIN 51794, the auto-ignition temperature of the test material NAF-AO was determined to be greater than 375 °C at an ambient pressure of ca. 101 kPa.
