ASTM D1655 Fully Automatic Low-Temperature Kinematic Viscometer
KN-1655 Fully Automatic Low-Temperature Kinematic Viscometer conforms the ASTM D445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity). It is used to test the of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid. Under certain constant temperature. The range of kinematic viscosities covered by this apparatus method is from 0.2 to 300 000 mm2/s at all temperatures

ASTM D2983 Low Temperature Brookfield Viscometer
The low-temperature, low-shear-rate viscosity of automatic transmission fluids, gear oils, torque and tractor fluids, and industrial and automotive hydraulic oils are of considerable importance to the proper operation of many mechanical devices. Measurement of the viscometric properties of these oils and fluids at low temperatures is often used to specify their acceptance for service. This test method is used in a number of specifications.

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 D5293 Apparent Viscosity By Cold Cranking Simulator CCS
The CCS apparent viscosity of automotive engine oils correlates with low temperature engine cranking. CCS apparent viscosity is not suitable for predicting low temperature flow to the engine oil pump and oil distribution system. Engine cranking data were measured by the Coordinating Research CouncilThe measurement of the cranking viscosity of base stocks is typically done to determine their suitability for use in engine oil formulations. A significant number of the calibration oils for this met

ASTM D4684 Yield Stress And Apparent Viscosity Of Engine Oils
An engine oil sample is held at 80°C and then cooled at a programmed cooling rate to a final test temperature and held for a specified time period. At the end of this period, a series of increasing low torques are applied to the rotor shaft until rotation occurs to determine the yield stress, if any is exhibited. A higher torque is then applied to determine the apparent viscosity of the sample.

ASTM D1092 Apparatus for Apparent Viscosity of Lubricating Grease
KN-1092 Apparatus for Apparent Viscosity of Lubricating Grease conforms to ASTM D1092 Standard Test Method for Measuring Apparent Viscosity of Lubricating Grease. This Test method covers measurement, in poises, of the apparent viscosity of lubricating greases in the temperature range from -54℃ to 38℃ (-65℉ to 100℉). Measurements are limited to the range from 25P to 100000P at 0.1s-1 and 1P to 100P at 15000s-1. Apparent viscosity versus shear rate information can be useful in predicting pressure drops in grease distribution systems under steady-state flow conditions at constant temperature.
