Description of Content

This Draft Uganda Standard covers the test method for the measurement of the apparent viscosity of engine oil at low temperatures. A shear rate of approximately 0.2s-1 is produced at shear stresses below 100Pa. Apparent viscosity is measured continuously as the sample is cooled at a rate of 1°C/h over the range 5°C to 40°C, or to the temperature at which the viscosity exceeds 40000mPa.s (cP).
