Specific details on test material used for the study:
Storage conditions: The test item was stored in a metal bottle as received in the dark from the day of receipt (01. Dec. 2016) till the 18. Jan. 2017 at room temperature and is then stored in a closed vessel (original metal bottle) at 2.4- 8.0 °C in the dark.
Key result
Auto-ignition temperature:
235 °C
Atm. press.:
ca. 101 325 Pa

Pre-Determination

Ignition at 266.1°C in vessel, with 5 drops, delay 20 s, under 99682 Pa.

 Experiment  Value  Ignition delay  Drops used  Atmospheric pressure
 First test series  240°C  55 s  13   99682 Pa
 Second test series  240°C  53 s  13  99424 Pa
 Third test series  238°C  50 s  9  100278 Pa

Detailed observations are available in the study report.

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 235°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 substance was tested, under GLP, for its auto flammable properties, according to DIN 51794 standard (listed in EU A.15 guideline).

The auto ignition temperature was determined in three independent determinations. A lowest value of 238°C was found in the main test.

Therefore, the auto-ignition temperature (rounded down to a whole multiple of 5 °C) of test item was stated as 235°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:
235 °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.

Note that this parameter may show some variations, due to the UVCB nature of the substance.

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