Section 3. Filling the oil-cup

3. Filling the oil-cup.—The oil-cup having been previously cooled, by placing it bottom downwards in water at a temperature not exceeding 50° Fahrenheit, is to be rapidly wiped dry, placed on a level surface in a good light, and the oil to be tested is poured in very slowly, without splashing, until its surface is level with the point of the gauge which is fixed in the cup. The round bulb thermometer is inserted into the lid of the cup, care being taken that the projecting rim of the collar touches the edge of the socket; the test-lamp, prepared as already described, is placed in position, and the cover is then put on to the cup and pressed down so that its edge rests on the rim of the cup. 3. Directions for preparing and using the test-apparatus.—The water-bath and test-lamp are to be prepared in the manner prescribed in Part III of this Schedule. The oil-cup is to be filled with the liquefied oil, and the cover (into which both thermometers are to be previously inserted) placed on it, care being taken that the bulb of the additional thermometer is not brought into contact with the bracket-gauge fixed inside the cup. The oil-cup is then to be placed in a refrigerator, or plunged up to the projecting collar in water maintained at sufficiently low temperature, until both thermometers indicate the temperature at which the testing of petroleum is directed in Part III of this Schedule to be commenced. The oil-cup is then to be removed, wiped dry and placed in the water-bath, and the testing effected in the manner prescribed in Part III of this Schedule, the temperature indicated by the additional (vertical) thermometer alone being noted, and the average of three determinations, duly corrected for atmospheric pressure, being recorded as the flashing point of the sample, provided that no greater difference than 4° Fahrenheit exists between any two of such results.
