Pdsc test
Splet07. nov. 2024 · The pressure differential scanning calorimetry (PDSC) is a useful way of measuring the oxidative stability of vegetable oils in an accelerated mode; results are obtained faster due to the use of high temperature and pressure. PDSC method uses the fact that oil oxidation is an exothermic process. SpletSummary. The CEC L-85-T-99 pressure differential calorimetry (PDSC) test was developed in Europe for ACEA E5 specification for heavy duty diesel oils. This test differentiate …

A series of Accelerating Rate Calorimeter (ARC) and Thermo Gravimetric Pressurized Differential Scanning Calorimeter (TG/PDSC) tests was conducted on oil-rock systems from three light-oil reservoirs (Oils A, B and C) to screen and evaluate the potential of the air injection process. ARC tests helped determine, a priori, whether …
