Standard Test Method fo r Estimation of Engine Oil Volatility by Capillary Gas 
Chromatography, First Edition. (20 page(s), in English)   
6. Description of content: This Draft Uganda Standard covers the test method for the 
estimation of the amount of engine oil volatilized at 371° C (700°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  first 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 method.  
This test method uses the principles of simulated distillation methodology. This test 
method may be applied to both lubricant oil base stocks and finished lubricants containing 
additive packages. These additive packages generally contain high mole cular weight, 
nonvolatile 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/944
