Conclusions:
The test item is auto-ignitable with an auto-ignition temperature of 320 °C at 1033.7–1035.4 hPa.
Executive summary:

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of Reaction products of 3-methyl-5-[(1S,4aS,8aS)-5,5,8a- trimethyl-2- methylenedecahydro-1-naphthalenyl]-1-penten-3-ol, cyclized. Temperature at differing volumes of test substance were reduced in 2 °C increments until no ignition was observed.  The temperature prior to this point was considered the auto-ignition temperature.

The test item is auto-ignitable with an auto-ignition temperature of 320 °C at 1033.7–1035.4 hPa.

Description of key information

Auto-ignition temperature = 320 °C, EC A.15 (also see DIN Guide 51794 and IEC standard 79 -4), Anon. (2017).

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
