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 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 D5481 Apparent Viscosity At High Temperature And High Shear Rate By Multicell Capillary Viscometer HTHS
High-Temperature and High-Shear Rate Apparent Viscosity Tester (HTHS) covers the laboratory determination of high-temperature high-shear (HTHS) viscosity of engine oil at a temperature of 150℃ using a multicell capillary viscometer containing pressure, temperature, and timing instrumentation. The shear rate for this test method corresponds to an apparent shear rate at the wall of 1.4 million reciprocal seconds (1.4 3 106s-1).This shear rate has been found to decrease the discrepancy between this

ASTM D5800 Evaporation Loss Of Lubricating Oils By The Noack Method
The evaporation loss is of particular importance in engine lubrication. Where high temperatures occur, portions of an oil can evaporate. Evaporation may contribute to oil consumption in an engine and can lead to a change in the properties of an oil. Many engine manufacturers specify a maximum allowable evaporation loss. Some engine manufacturers, when specifying a maximum allowable evaporation loss, quote this test method along with the specifications.
