List of Measurement Results

 Series  Temperature (°C)
 Series 1  514
 Series 2  516
 Series 3  520

Atmospheric pressure during the measurement:

13.11.2012 1018 hPa

14.09.2012 1023 hPa

14.09.2012 1019 hPa

Atmospheric pressure and relative humidity of the air are of minor effects on measured auto-ignition temperature at temperatures above 150 °C.

Calculation

The lowest value out of these series is rounded down to the next value which may be divided by 5 (yielding an integer).

Conclusions:
Auto ignition temperature: ca. 510°C
Executive summary:

The auto-ignition temperature of the test item is determined to be ca. 510 °C at ca. 1020 hPa according to the EU method A. 15. "Auto-ignition temperature (liquids and gases)" in a GLP study.

Description of key information

The auto-ignition temperature of the test item is determined to be ca. 510 °C at ca. 1020 hPa according to the EU method A. 15. "Auto-ignition temperature (liquids and gases)" in a GLP study.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
510 °C

Additional information

Atmospheric pressure and relative humidity of the air are of minor effects on measured auto-ignition temperature at Temperatures above 150 °C, therefore the result is not affeced by a higher pressure as determined in the study.
