                                                                           Auto Ignition Test Apparatus

The Auto Ignition Temperature Test is performed to enable determination of hot and cool flame auto ignition temperatures of a liquid chemical (and solid chemicals*) in air at atmospheric pressure in a uniformly heated vessel. 

Auto Ignition is defined as the ignition of a material commonly in air as the result of heat liberation due to an exothermic oxidation reaction in the absence of an external ignition source such as a spark or flame.

The following standards (each with slight differences) are applicable to the test:

  •  ASTM E659 
  •  EC test A15
  •  DIN 51794
  • Other configurations

Within certain limitations, the test can also be used to determine the auto ignition of solid chemicals which readily melt and vaporise at temperatures below the test temperature.
