The XF-5481 HTHS High Temperature and High Shear Lubricating Oil Dynamic Viscometer (Multiple Capillary Viscometer Method) is a standard test method used by our company to measure apparent viscosity at high temperatures and high shear rates using a multiple capillary viscometer in strict accordance with ASTM D5481 Standard Test Method for Measuring Apparent Viscosity at High-Temperature and High-Shear Rate by Multicell Capillary Viscometer The technical requirements for manufacturing petroleum product testing instruments. It is suitable for determining the apparent viscosity of lubricating oil at high temperature and high shear rate, that is, measuring the high-temperature and high shear dynamic viscosity of lubricating oil, HTHS index.
The XF-5481 HTHS high-temperature and high shear lubricating oil dynamic viscosity tester (multiple capillary viscometer method) is also suitable for measuring the dynamic viscosity and high-temperature and high shear characteristics of lubricating oil under high-temperature and high shear rate conditions using the SHT 0703-2001 apparent viscosity measurement method (multiple capillary viscometer method).
XF-5481 HTHS High Temperature and High Shear Lubricating Oil Dynamic Viscometer (Multiple Capillary Viscometer Method). The testing principle of HTHS instrument is to flow the sample out of the capillary viscometer under the pressure of nitrogen (carbon dioxide) at 150 ℃± 0.1 ℃ test conditions. The apparent shear rate of the capillary viscometer can be obtained by the outflow time and pressure of the sample, and the apparent viscosity of the oil corresponding to the measured pressure can be obtained by calibrating the curve of each viscometer cell.
