5. Title, number of pages and language(s) of the notified document: DUS 2054:2018 
Standard Test Method f or Determination of Moderately High Temperature Piston Deposits 
by Thermo -Oxidation Engine Oil Simulation Test -TEOST MHT, First Edition. (12 page(s), 
in English)   
6. Description of content: This Draft Uganda Standard covers the test method for the 
procedu re 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.
