Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2014-01-28 to 2014-01-30
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The study was conducted according to EU/DIN method, and under GLP. No significant deviation was reported. Test substance is adequately specified with purity. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Deviations:
yes
Remarks:
time lag before ignition not reported
Qualifier:
according to guideline
Guideline:
other: DIN 51794 (2003): Determination of ignition temperature
Principles of method if other than guideline:
Not applicable
GLP compliance:
yes (incl. QA statement)
Remarks:
inspected on January 22 and 23, 2013 / signed on March 22, 2013
Key result
Auto-ignition temperature:
ca. 265 °C
Atm. press.:
ca. 992 - ca. 998.4 hPa

Preliminary Test

In the preliminary test, the lowest temperature at which an ignition occurred was 418 °C.

Results are within the required range of 20 °C, therefore the validity criterion is fulfilled.

According to observations in the main test series, the auto-ignition temperature rounded down with an accuracy of 5 °C was determined to be 415 °C.

Conclusions:
This parameter/method is not relevant for classification, however the information is useful regarding 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 guideline A.15 and Standard DIN 51794. 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 415 °C at 989.6 -996.0 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:
415 °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 is not relevant for classification; however the information is useful regarding potential additional fire hazard.
