test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to guideline
Guideline:
other: German standard method "DIN 51794"
Deviations:
no
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))

Auto-ignition temperature:
270 °C
Atm. press.:
994 hPa
Remarks on result:
other: lowest value of several test runs, where no ignition occured
Conclusions:

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). a small portion of the flammable substance under test was introduced into an open conical flask (Erlenmeyer flask). The flask was heated in an electric furnace and it was observed whether ignition takes place at the prevailing temperature. Finally, any vaporizable components left in the flask were blown out with air. The auto-ignition temperature was measured to be 270 °C at 994 hPa.

Description of key information

The auto-ignition temperature was measured to be 270 °C at 994 hPa. 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
270 °C
