minimum ignition temperature test

The minimum ignition temperature (MIT) test determines the lowest temperature required to ignite adust cloud in air.Hot surfaces capable of igniting dust clouds can exist in a number of situations in industry. Insidefurnaces, burners, and dryers of various kinds they constitute part of the process equipment itself.Hot surfaces can also be generated by electrical heating and hot work, and by frictional overheating ofbearings and other mechanical parts. In areas in industry where explosible dust clouds may occur, it is clearly important to know theminimum temperatures of any hot surfaces there, at which explosible dust clouds making contact withthese surfaces, will ignite.As soon as adequate estimates of these minimum temperatures are available, adequate precautions canbe taken to ensure that temperatures of hot surfaces in such areas do not rise to these value.
