5. Title, number of pages and language(s) of the notified document: DUS 2050:2018 
Standard Tes t Method for Evaluation of Rust Preventive Characteristics of Automotive 
Engine Oils, First Edition. (20 page(s), in English)    
6. Description of content: This Draft Uganda Standard covers an estimation of the amount 
of engine oil volatilized at 371°C (70 0°F). This test method can also be used to estimate 
the amount of oil volatilized at any temperature between 126°C and 371°C, if so desired.  
This test method is limited to samples having an initial boiling point (IBP) greater than 
126°C (259°F) or the firs t calibration point and to samples containing lubricant base oils 
with end points less than 615°C (1139°F) or the last n -paraffins in the calibration mixture. 
By using some instruments and columns, it is possible to extend the useful range of the 
test meth od. 
The test method uses the principles of simulated distillation methodology and may be 
applied to both lubricant oil base stocks and finished lubricants containing additive 
packages. These additive packages generally contain high molecular weight, nonvol atile 
components that do not elute from the chromatographic column under the test conditions.  
The calculation procedure used in this test method assumes that all of the sample elutes 
from the column and is detected with uniform response. This assumption is  not true for 
samples with nonvolatile additives, and application of this test method under such 
conditions will yield results higher than expected. For this reason, results by this test 
method are reported as area percent of oil.  G/TBT/N/UGA/945
