Date: 19/02/2018-20/02/2018

Barometric Pressure: 983 mBar, 986 mBar

Relative Humidity: 31%, 45%

Ambient Temperature: 22.8 °C, 21.8 °C

 

It should be noted that the flask is open to the atmosphere; therefore, vapours are escaping from the test apparatus over the course of the test. The more volatile vapours will vent out first which may minimize the probability of these vapours auto igniting in the flask.

 

Conclusions

The autoignition temperature was tested for the test item and determined to be 254 °C. The testing was performed in accordance with ASTM E659.
