Standard Test Method for Estimation of Engine Oil Volatility by Capillary Gas Chromatography

Importancia y uso:

5.1 The determination of engine oil volatility at 371 °C (700 °F) is a requirement in some lubricant specifications.

5.2 This test method is intended as an alternative to Test Methods D5800 and the Noack method for the determination of engine oil volatility (CEC L-40–93). The data obtained from this test method are not directly equivalent to Test Method D5800. The calculated results of the oil volatility estimation by this test method can be biased by the presence of additives (polymeric materials), which may not completely elute from the gas chromatographic column, or by heavier base oils not completely eluting from the column. The results of this test method may also not correlate with other oil volatility methods for nonhydrocarbon synthetic oils.

5.3 This test method can be used on lubricant products not within the scope of other test methods using simulated distillation methodologies, such as Test Method D6352.
