ASTM D5481 High-Temperature And High-Shear Viscometer (HTHS)

High-Temperature And High-Shear Viscometer (HTHS)

The high temperatures and high shear viscometer mainly measures the apparent viscosity of lubricating oil at high temperature and high shear rate. The test principle is that under the test condition of 150 °C, under the pressure of nitrogen (carbon dioxide), the sample flows out from the capillary viscometer, and the apparent shear rate of the capillary viscometer can be obtained from the outflow time and pressure of the sample. To achieve a certain apparent viscosity, the curve corrected by each viscometer pool corresponds to the measured viscosity of the oil viscosity.

Reference Standards:

• SH/T-0703 Standard test method for measuring apparent viscosity at high-temperature and high-shear rate by multicell capillary viscometer.

• ASTM D5481 Standard Test Method for Measuring Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer.
