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 D1840 Naphthalene Hydrocarbons in Aviation Turbine Fuels
KN-UV-VIS Spectrometer conforms to ASTM D1840 Standard Test Method for Naphthalene Hydrocarbons in Aviation Turbine Fuels by Ultraviolet Spectrophotometry. This test method for naphthalene hydrocarbons is one of a group of tests used to assess the combustion characteristics of aviation turbine fuels of the kerosene boiling range. The naphthalene hydrocarbon content is determined because naphthalenes, when burned, tend to have relatively larger contribution to a sooty flame, smoke, and thermal radiation than single ring aromatics.

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.

ASTM D445 Six Holes Kinematic Viscosity Tester
The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature. The kinematic viscosity (determined value) is the product of the measured flow time and the calibration constant of the viscometer. Two such determinations are needed from which to calculate a kinematic viscosity result that is the average of two acceptable determined values
