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 substance was tested for its autoflammable properties, according to standard DIN 51794 (listed in EU A15 guideline). Test material was injected into a heated flask, until the lowest temperature at which ignition occurs was determined.

The test material has been determined to have an auto-ignition temperature of 390 ± 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:
390 °C

Additional information

A reliable experimental study, conducted according to a recognized DIN/EU method, is available. Despite minor restrictions due to incomplete testing, 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.
