Ignition studies of such fine forest fuels as needles, rotten wood, and grass have been hindered by the lack of suitable ignition producing device and a reliable test procedure. Ignition test were conducted at the Northern Forest Fire Laboratory on a variety of fuels. As a result of these tests, a standarized procedure was adopted and modifications wre made to the Stockstad-Lory ignition furnace that overcame these difficulties. A new ignition boat was designed and a stationary thermocouple was introduced for monitoring the ignition chamber temperatures. The test procedures adopted considered opertator reaction time, introduction of the ignition boat in the isothermal ignition chamber atmosphere, the position of the pilot flame, and the effect of its introduction into the ignition chamber.
