DUS 2054:2018 Standard Test Method for Determination of Moderately High Temperature Piston Deposits by Thermo-Oxidation Engine Oil Simulation Test-TEOST MHT, First Edition. (12 page(s), in English)
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.
