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. SpletA test program was performed on the nine commercial greases to compare Product Data sheet claims with both commonly used static heat resistance test results, and several dynamic life tests....

Oxidation Stability of Lubricants Measured by a PDSC Technique

Splet29. nov. 2024 · The PDSC test was a very useful method for determining the oxidative stability of oils due to the short time of the analysis, the small amount of sample required, and the fact that it did not require chemical reagents for the test. PDSC has the potential to be used as an alternative method for evaluation of the stability of edible oils. SpletThis test may be used to compare antioxidants and may predict the relative life of a lubricant.
