Preliminary Test

An approximate value of the ignition temperature of the test item was first determined by a preliminary test. The following table summarizes the results of the preliminary test. An "ignition" is indicated as "+" and "no ignition" as "-". 5 drops were added into the Erlenmeyer flask at each temperature.

In the preliminary test, the lowest temperature at which an ignition occurred was 284 °C.

 

 

Main Test

The lowest temperatures at which an ignition occurred in the main tests are given as follows:

Based on results of the main test series, the lowest auto-ignition temperature was 232 °C.

 

Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 230 °C.

 

For information:

DIN EN 14522: The auto-ignition temperature reduced by 1.5 % and rounded to the nearest integer temperature was determined as 228 °C.

 

 

Final Results

The test item has an auto-ignition temperature of 230 °C according to the Regulation EC No. 440/2008 Method A.15. Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature.
