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 0.2 s-1 is produced at shear stresses below 100 Pa. 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 40 000 mPa.s (cP).

This Draft Uganda Standard covers the test method for the procedure to determine the mass of deposit formed on a specially constructed test rod exposed to repetitive passage of 8.5g of engine oil over the rod in a thin film under oxidative and catalytic conditions at 285°C. The range of applicability of the Moderately High Temperature Thermo-Oxidation Engine Test (TEOST MHT) test method as derived from an interlaboratory study is approximately 10mg to 100mg. However, experience indicates that deposit values from 1mg to 150mg or greater may be obtained. This test method uses a patented instrument, method and patented, numbered, and registered depositor rods traceable to the manufacturer and made specifically for the practice and precision of the test method.

This Draft Uganda Standard covers test method for the required procedures to evaluate the comparative ability of rubber and rubber-like compositions to withstand the effect of liquids. It is designed for testing: (1) specimens of vulcanized rubber cut from standard sheets (see Practice D3182), (2) specimens cut from fabric coated with vulcanized rubber (see Test Methods D751), or (3) finished articles of commerce (see Practice D3183). This test method is not applicable to the testing of cellular rubbers, porous compositions, and compressed sheet packing, except as described in 12.2.2.

Products Covered: RUBBER AND ARTICLES THEREOF (HS code(s): 40); Rubber (ICS code(s): 83.060)

This Draft Uganda Standard covers four procedures for determining the evaporation loss of lubricating oils (particularly engine oils). Procedure A uses the Noack evaporative tester equipment; Procedure B uses the automated non-Woods metal Noack evaporative apparatus; Procedure C uses Selby-Noack volatility test equipment, and Procedure D uses the Noack S2 test equipment. The test method relates to one set of operating conditions but may be readily adapted to other conditions when required. Noack results determined using Procedures A and C provide equivalent results and Procedures B and D provide equivalent results. However, A/C compared to B/D show consistent differences. Procedure A/C give slightly lower results versus Procedure B/D on formulated engine oils, while Procedure A/C give higher results versus Procedure B/D on base stocks.
