This standard specifies a method for determining the apparent viscosity of engine oils at high temperature and high shear (HTHS) using a multi-capillary tubing Viscosity meter at 150 ° C with a wall apparent shear rate of 1.4x10 ° s ^ (-1). For engine oils, the apparent viscosity is determined directly using the corrected Linear dispersion established by a Newtonian calibrated oil with an apparent viscosity of 1.5mPa · s to 5.0mPa · s at 150 ° C. Precision applies only to engine oils with an apparent viscosity of 1.45mPa · s to 5.05mPa · s at 150 ° C. Users should ensure that appropriate safety precautions are in place before using this standard.
