Key result
Auto-ignition temperature:
302 °C
Atm. press.:
101 kPa

ASTM E-659 Auto-Ignition
Hot Flame Auto-Ignition Temperature= 575 F
Hot Flame Time Lag= 9.1 sec.

An Auto-ignition temperature value of 302°C at 101 kPa was determined for the substance in a reliable study conducted according to method ASTM E-659. No further details are available.

Description of key information

Auto-ignition temperature: 302°C at 1013 hPa (ASTM E-659)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
302 °C

Additional information

An auto-ignition temperature value of 302°C at 1013 hPa was determined for the substance in accordance with national standard method ASTM E-659. Although full details are not available, the result is considered to be reliable and selected as key study.

In a secondary source to which reliability could not be assigned, an auto-ignition temperature of 285°C was reported for the substance.
