Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Auto-ignition temperature:
420 °C
Atm. press.:
1 019 hPa
Remarks on result:
other:

An ignition was observed at a temperature of 430 °C at a sample size of nine drops. Proceeding from this temperature, the lowest result in the main test run was found to be 425 °C. A repeat test was performed using fresh ignition vessels. The lowest result in the repeat test was found to be 430 °C. The barometric pressure was 1019 hPa at the time of the test runs. Bearing in mind the significance of the ignition temperature for risk assessment, the result is not to be reported as the mean, but as the lowest value, where no ignition occurs.

Conclusions:
Based on tests according to EC-Test Procedure A 15 (DIN 51794) the auto ignition temperature of the test item is specified as 420 °C at 1019 hPa..
Executive summary:

The test was performed as stipulated in EC Test Procedure A 15 'Auto-ignition temperature (liquids and gases)' (DIN 51794 - Determining the ignition temperature of petroleum products). An ignition was observed at a temperature of 430 °C at a sample size of nine drops. Proceeding from this temperature, the lowest result in the main test run was found to be 425 °C. A repeat test was performed using fresh ignition vessels. The lowest result in the repeat test was found to be 430 °C. The barometric pressure was 1019 hPa at the time of the test runs.

Description of key information

Based on tests according to EC-Test Procedure A 15 (DIN 51794) the auto ignition temperature of the test item is specified as 420 °C at 1019 hPa.

Key value for chemical safety assessment
