ASTM D4603 Inherent Viscosity Of PET By Glass Capillary Viscometer
The inherent viscosity is determined by measuring the flow time of a solution of known polymer concentration and the flow time of the pure solvent in a capillary viscometer at a fixed temperature. The inherent viscosity value is calculated from the flow time values

ASTM D4603 Inherent Viscosity Apparatus for PET Polyester
KN-4603 Inherent Viscosity Apparatus for PET Polyester conforms the ASTM D4603 Inherent Viscosity Apparatus for PET Polyester. It is used to test the of liquid petroleum products, both transparent and opaque. It used for the determination of the inherent viscosity of poly (ethylene terephthalate) (PET) soluble at 0.50% concentration in a 60/40 phenol/1,1,2,2-tetrachloroethane solution by means of a glass capillary viscometer. Highly crystalline forms of PET that are not soluble in thsi solvent mixture will require a different procedure.

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 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.
