ASTM D2171 Apparatus for Viscosity of Asphalts
KN-2171 Apparatus for Viscosity of Asphalts conforms to ASTM D2171 Standard Test Method for Viscosity of Asphalts by Vacuum Capillary Viscometer. The viscosity at 60℃ characterizes flow behavior and may be used for specification requirements for cutbacks and asphalt binders. This time is measured for a fixed volume of the liquid to be drawn up through a capillary tube by means of vacuum, under closely controlled conditions of vacuum and temperature. The viscosity in Pascal-seconds is calculated by multiplying the flow time in seconds by the viscometer calibration factor.

ASTM D938 Congealing Point of Petroleum Waxes and Petrolatum
KN-938 Congealing Point of Petroleum Waxes and Petrolatum conforms to ASTM D938 Standard Test Method for Congealing Point of Petroleum Waxes, Including Petrolatum. Congealing point is a wax property that is of interest to many petroleum wax consumers. The procedure described here measures the temperature at which a sample being cooled develops a “set” or resistance to flow. At that temperature, the wax may be at or close to the solid state, or it may be semisolid and quite unctuous, depending on the composition of the wax or petrolatum being tested. In the case of petrolatums, congealing property is associated with the formation of a gel structure as the sample cools. A sample of wax is melted and a droplet is made to adhere to the bulb of a thermometer. Using a prewarmed flask as an air jacket, the droplet on the bulb is allowed to cool at a fixed rate until it congeals. The congealing point is observed as the temperature at which the droplet ceases to flow as the thermometer is turned.

ASTM D721 Oil Content Of Petroleum Waxes
The oil content of a wax may have significant effects on several of its properties, such as strength, hardness, flexibility, scuff resistance, coefficient of friction, coefficient of expansion, melting point, and oil straining. The importance of these effects may be dependent upon the ultimate use of the wax

ASTM D2872 Rolling Thin Film Oven Test
this oven indicates approximate change in properties of asphalt during conventional hot-mixing ar about 150℃ as indicated by viscosity and other rheological measurements.it yields a residue which approximates the asphalt condition as incorporated in the pavement.if the mixing temperature differs appreciably from the 150℃ level. more or less effect on properties will occur. this oven also can be used to determine mass change,which is a measure of asphalt volatility

ASTM D4402 Rotational Viscometer for Asphalt Viscosity
KN-4402 Rotational Viscometer for Asphalt Viscosity conforms to ASTM D4402 Standard Test Method for Viscosity Determination of Asphalt at Elevated Temperatures Using a Rotational Viscometer. A rotational viscometer is used to measure the apparent viscosity of asphalt at elevated temperature. The torque on the apparatus-measuring geometry, rotating in a thermostatically controlled sample holder containing a sample of asphalt, is used to measure the relative resistance to rotation. The torque and speed are used to determine the viscosity of the asphalt in pascal seconds, millipascal seconds, or centipoise.
