Organization: ASTM
Publication Date: 10 April 1996
Status: inactive
Page Count: 5
ICS Code (Lubricants, industrial oils and related products): 75.100
scope:

This test method covers the laboratory determination of high-temperature high-shear (HTHS) viscosity of engine oils at a temperature of 150°C 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 × 10(6); s−1).³ This shear rate has been found to decrease the discrepancy between this test method and other high-temperature high-shear test methods ³ used for engine oil specifications. Viscosities are determined directly from calibrations that have been established with Newtonian oils with viscosities from 2 to 5 mPa·s at 150°C.

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