Closed Cup Flash Point Testing


How it Works

Flash point is a property of a material that describes the temperature at which the sample will ignite in the presence of an open flame.  A closed cup flash point testing apparatus heats a sample to a specified temperature and holds it at that temperature for one minute to allow time for volatiles within the sample to fill the closed cup.  After one minute the sample is exposed to a flame through a hole in the top of the cup.  If it does not ignite, the temperature is increased and the test repeated until the sample ignites.  The temperature at which the sample ignites is called the flash point.


Our Equipment

FAI Materials Testing owns a small-scaled closed cup flash point testing apparatus.  The open flame fuel is propylene gas and the heater is electric with a closed-feedback loop for setting the temperature to remain constant.  Liquid nitrogen is used to bring the sample cup down to -10°C for below room temperature flash point testing.  We perform our testing in accordance with ASTM D3278 - Standard Test Methods for Flash Point of Liquids by Small Scale Closed-Cup Apparatus.
