Engine oils; Lubricating preparations (including cutting-oil preparations, bolt or nut release preparations, anti-rust or anti-corrosion preparations and mould release preparations, based on lubricants) and preparations of a kind used for the oil or grease treatment of textile materials, leather, furskins or other materials, but excluding preparations containing, as basic constituents, 70% or more by weight of petroleum oils or of oils obtained from bituminous minerals.

DUS 2044:2018 Standard test method for determination of yield stress and apparent viscosity of used engine oils at low temperature, First Edition. (20 page(s), in English)
This Draft Uganda Standard covers the test method for the measurement of the yield stress and viscosity of engine oils after cooling at controlled rates over a period exceeding 45h to a final test temperature between -10°C and -40°C. The precision is stated for test temperatures from -40°C to -15°C. The viscosity measurements are made at a shear stress of 525 Pa over a shear rate of 0.4 s-1 to 15 s-1. This test method is suitable for measurement of viscosities ranging from 4000 mPas to >400000 mPas, and is suitable for yield stress measurements of 7 Pa to >350 Pa. This test method is applicable for used diesel oils. The applicability and precision to other used or unused engine oils or to petroleum products other than engine oils has not been determined.
