Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
The study was conducted according to an internationally recognised method, but without detailed documentation. The test substance is adequately identified. Therefore validation applies with restrictions.
Qualifier:
according to guideline
Guideline:
DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
GLP compliance:
no
Key result
Auto-ignition temperature:
250 °C
Atm. press.:
986 mBar

P = 986 mbar

V = 200 μL

τ lag = 104 s

AIT = 250°C (+/- 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 substance was tested according to DIN 51794 standard (listed in EU A.15 guideline).

The test substance was injected into the automated instrument, and volume, time lag for ignition and atmospheric pressure were recorded.

The auto-ignition temperature of test item was found at 250°C at 986 mbar.

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:
250 °C

Additional information

A reliable experimental study, conducted according to a recognized DIN/EU method and under GLP, is available. Despite restrictions due to lack of details, 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.
