Standard test method for evaporation loss of lubricating oils by the Noack method, First 
Edition. (43 page(s), in English)   
6. Description of content: This Draft Uganda Standard covers four procedures for 
determining the evaporation loss of lub ricating 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.
