- Executive summary:
The auto ignition temperature of the test item was determined in an experimental study according to EC-Guideline 92/69/EWG A.15 and DIN 51794. The lowest ignition temperature was determined from a series of ignition tests in which temperature and sample size were varied. The ignition temperature was then reported as the lowest result obtained in a number of test series. The barometric pressure was 1016 hPa at the time of the test runs. The lowest ignition result in the main test run and, in the repeat, test was found to be 255 °C.
Reference
In every ignition test, 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 lowest ignition temperature was determined from a series of ignition tests in which temperature and sample size were varied. The ignition temperature was then reported as the lowest result obtained in a number of test series. The barometric pressure was 1016 hPa at the time of the test runs.
The lowest ignition result in the main test run and, in the repeat, test was found to be 255 °C.
Description of key information
