Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From October 07 to 08, 2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The study was conducted according to an internationally recognised method, and under GLP. No significant deviation was reported. The test substance is adequately characterised. Therefore full validation applies.
Qualifier:

Key result
Auto-ignition temperature:
265 °C
Atm. press.:
992 - 998.4 hPa

Preliminary Test

In the preliminary test, the lowest temperature at which an ignition occurred was 286 °C.

Results are within the required range of 10 °C, therefore the validity criterion is fulfilled.

According to observations in the main test series, the auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined to be 265 °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 for its autoflammable properties, according to EU method A.15 and Standard DIN 51794.

The test material was injected into a heated flask, until the lowest temperature at which ignition occurs was determined. Three main test series were performed.

The test material has been determined to have an auto-ignition temperature of 265 °C at 992.0 -998.4 hPa.

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:
265 °C

Additional information

A fully reliable experimental study, conducted according to a recognized EC/DIN method, is available. Therefore it is considered as a key study, and the result is retained as key data.

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