Description of Content

This Draft Uganda Standard covers the test method for the laboratory determination of apparent viscosity of engine oils and base stocks by cold cranking simulator (CCS) at temperatures between –10°C and 35°C at shear stresses of approximately 50000Pa to 100000Pa and shear rates of approximately 105 to 104 s1 for viscosities of approximately 900mPa·s to 25000 mPa·s. The range of an instrument is dependent on the instrument model and software version installed. Apparent Cranking Viscosity results by this method are related to engine-cranking characteristics of engine oils.
