ASTM D2170 Viscosity Of Asphalts By Vacuum Capillary Viscometer
the kinematic viscosity characterizes flow behavior. the method is used to determine the consistency of bitumen as one element in establishing the uniformity of shipments or sources of supply. the specifications are usually at temperature of 60 and 135℃.

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 D217 Motorized Grease Worker
Cone penetration test results provide one measure of the consistency of a grease. Worked penetration results are required to determine to which NLGI consistency grade a grease belongs. Undisturbed penetration results provide a means of evaluating the effect of storage conditions on grease consistency
