Performance of the test
The timer was started as soon as the sample was injected into the flask and the time of injection was noted down in the raw data. The inside of the flask was observed in total darkness by means of a mirror placed at an appropriate angle above the flask. As ignition was not observed within 10 min, the test item is considered to be nonflammable at 150°C. The flask was completely purged for every replication with a hot air gun for about 2 minutes and the timer was reset. The above experiment was repeated with the following temperatures and the observations were recorded. The test was repeated at temperatures of 180, 210, 240, 270, 300, and 330 °C (at 30°C increment rate). Time was allowed to attain thermal equilibrium between the trials. As ignition was not observed in 10 min, the test item is considered to be nonflammable at 330°C. The flask was completely purged for every replication with a hot air gun for about 2 minutes and the timer was reset. The test was repeated at a set temperature of 360°C (30°C increment rate). Time was allowed for attainment of thermal equilibrium between the trials. As ignition was observed, the timer was stopped and the time interval between sample insertion and ignition was recorded as ignition delay time. The atmospheric pressure was also recorded using the barometer. The test interval was narrowed to 3°C to determine the break point between ignition and non-ignition. The test was repeated at 357°C and ignition was observed at an atmospheric pressure of 1016 hPa. The test was repeated at 354°C and no ignition was observed at an atmospheric pressure of 1016 hPa. The procedure was repeated by using a smaller sample volume (50 and 70 μL). There was no ignition with the decrease of sample volume at 357°C. The procedure was repeated by using a larger sample volume (150 μL). There was no ignition with the increase of sample volume at 354°C. The experiment was completed at a set temperature of 357°C to get the ignition for both replications at a sample volume of 100 μL.
Results
The results of the study revealed that the test item has a cool-flame auto ignition temperature (CFT) of 357.1 and 357.3°C and a hot-flame auto ignition temperature (AIT) of 357.3 and 357.5°C for replicates R1 and R2, respectively, at an atmospheric pressure of 1016 hPa with an ignition delay time of 2 seconds.
