Fire Test.--The fire test shall be made by continuing the flash test, the operation being the same except in the application of the test flame. The flame in the fire test shall he quickly brought to one-sixteenth (Me) inch above the surface of the oil near the center of the cup and as quickly removed. The fire teBt is usually from forty (40) degrees F. (40"C.) to eighty (80) degrees F. (276C.) higher than the flash test; the temperature to which the oil must be heated to cause it to give off gases which will burn continuously when a flame is applied above the surface of the oil, shall be the fire test. 4. Viscosity Test--The viscosity test shall be made by using the Saybolt Universal Viscosimeter. The oil tube shall be swabbed with the plunger accompanying the instrument by using oil from sample, making sure the overflow tube is not obstructed. Strain the oil into the oil tube at a temperature not above that of the bath, stir until the oil is of the test temperature throughout, remove the thermometer, remove the excess oil from the overflow chamber with the pipette and proceed with the test. The elapsed time in seconds required for the oil to fill the flask to the 60 c.c. mark on the neck shall be the viscosity of the oil. 5. Cold Test.--(a) The cold test shall be made by using a glass jar approximately one and one-fourth (IK) inch in diameter and four (4) to five (5) inches high, provided with a tightly fitting cork. The glass jar shall be incased in a closely fitting metal jacket, which shall be provided at the bottom with a disc of cork or felt one-fourth (K) inch thick.
