The auto ignition temperature (result of determination) is the lowest value from the lowest values of the three experiments, rounded down to a whole multiple of 5 °C. Therefore, the auto ignition temperature is stated as 430 °C.

Detailed observations are available in the study report.

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 substance was tested under GLP, according to DIN 51794 standard (listed in EU A.15 guideline).

The test substance was injected into a heated flask, until the lowest temperature at which ignition occurs was determined. Three independent determinations were performed.

The auto-ignition temperature (rounded down to a whole multiple of 5 °C) of test item was stated as 430°C at 98184 – 99025 Pa.

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:
430 °C

Additional information

A fully reliable experimental study, conducted according to a recognized DIN/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.
