The temperature when a flame first jumps from the testflame to the oil is called the flash point. A subdued light andfreedom from drafts are essential to satisfactory observations. The Am. Soc. Testing Mat. (Committee D-21) has made the TagUabueinstrument the standard for obtaining the flash and fire point by the closedtester 224 FUEL, GAS, WATER AND LUBRICATION After the flash point has been obtained the fire point is foundby continuing the heat till a flame is produced which continuesto burn. This temperature is designated as the fire point. Viscosity.—The specific viscosity of a hquid is the time takenfor a given quantity to flow through an orifice as compared
