accuracy: +/-5°C

Conclusions:
This parameter/method is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
No particular hazard is anticipated in normal conditions of storage.
Executive summary:

The auto-ignition temperature of the test substance was measured under GLP according to IEC 79-4 method (listed in EU A15 guideline). The test substance was injected into a heated flask, until the lowest temperature at which ignition occurs was determined. The relevant parameters were recorded for the final result.

The auto-ignition temperature of the test substance has been determined to be 356 ± 5 °C.

Description of key information

No particular hazard is anticipated in normal conditions of storage.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
356 °C

Additional information

A fully reliable experimental study, conducted according to a recognized IEC/EU method and under GLP, is available. It is considered as a key study. The result is retained as key data.

This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
