ASTM D5481 Standard Test Method for Measuring Apparent Viscosity at High Temperature and High Shear Rate with a Multi-Cell Capillary Viscometer

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D5481 standard. This test method involves the laboratory determination of the high temperature high shear (HTHS) viscosity of motor oils at 150°C using a multi-cell capillary viscometer that includes pressure, temperature and timing instrumentation.

The shear rate for this test method corresponds to an apparent shear rate of 1,4 million reciprocal seconds at the wall. This shear rate has been found to reduce the mismatch between this test method and other high temperature high shear test methods.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
