auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Study initiation date: 29 July 2009 Study completion date: 19 November 2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Version / remarks:
Directive 92/69/EEC, Official Journal L 383 A 1992
Deviations:
no
Qualifier:
according to guideline
Guideline:
DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
Deviations:

GLP compliance:
yes
Key result
Auto-ignition temperature:
415 °C
Atm. press.:
1 009 hPa
Remarks on result:
other: Lowest ignition temperature of all single results of the main test (consisting of three tests)

Details on measurements:

Lowest ignition temperature [°C]:

Test 1: 420;

Test 2: 415;

Test 3: 415;

The measured lowest ignition temperatures of the main test are > 300 °C and do not differ by more than 20 °C, thus the test is satisfactory.

The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded down to multiples of 5 °C.

Auto-ignition temperature: 415 °C

Conclusions:
Auto-ignition temperature (EU method A.15): 415 °C (1009 hPa)
Executive summary:

The auto-ignition temperature of the submission substance was determined compliant with GLP according to EU test method A.15 [Directive 92/69/EEC, Official Journal L 383 A 1992] and DIN 51 794.

The reliable study produced the following result (Lowest ignition temperature of all single results of the main test (consisting of three tests)):

Auto-ignition temperature: (1009 hPa): 415 °C

Description of key information

Auto-ignition temperature (EU test method A. 15 / DIN 51 794): 415 °C at 1009 hPa

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
415 °C
