3 != Height Of Still over all, 29.5 C.M. From bottom of bowl to lower side of tubular, 20.3 C,y, 3 From neck of flask tO end of condenser, 97.7 C.M. i The still shall be properly connected to condenser , same resting On a support with the two pieces Of NO. 20 mesh gauze between the bottom of still and fire, place asbestos cylinder around still,bringing tubular out through small hole inside. Place thermometer so that top of mercury bulb will be at the lower opening of tubular. ( d") ASPHALT. ------------ After being freed from water it shall contain hot less than ninety (90.0) per cent Of asphalt, having at a temperature of seventy (70.0) degrees Fahrenheit , a I Penetration of eighty ($0.0) degrees District of OolumUla Standard. The percentage of asphalt shall be determined by heating twenty --five grams (25.0) in a No. lbrass Spherical dish with a radius of four (4.0 and two tenths (0.2) centimeters inside measurements , in a Blackmar or Richardson type of oven maintained at a uniform temperature of four hundred and thirty (43) degrees Fahrenheit,( 400' Is usual:.) until it has reached the proper consistency, when the weight of the residium is determined and the per cent calculated. I (The eemperature Of the oven shall be taken with the bulb of the thermometer creating on the bottom thereof. (K) DUCTILITY. -- The ductility of the asphalt as above p2apared having a penetration of ! between seventy fine (75.0) and eighty --five ($5.0) degrees District of Columbia standard a shall not be less than one hundred and ten (110.0 ) centimeters. This teat is to be made by Immersing the asphalt in water which is kept at a uniform temperature Of seventy—seven (77.0) degrees Fahrenheit for least thirty (30) minutes , using the "Dow" asphalt mould and pulling apart at a uniform rate of speed of five (5) centimeters per minute. THERMAL READINGS. ------------------- It must be delivered at the point of applicationuat a temperature not less than three hundfad (300.0) degrees Fahrenheit. ( M) THMUML CORREOTIONS. ------ In determining the quality f oil delivered the correction for expansion by heat shall be as follows, From the measured Volume Of oil received at any temperature above sixty (60.0) degrees Fahrenheit, an amount equivalent to triree tenths of }� said. one per cent for every ten degrees above sixty degrees Fahrenheit shall be subtracted as the correction for expansion by heat. -For the purpose of measuring this oil a temperature Of sixty degrees Fahrenheit shall be deemed the normal temperature.
