Evaporation Loss | Phosphorous Volatility
The evaporation loss/volatility of engine oils is of particular importance to the automotive industry as it closely relates to oil consumption in an engine and can lead to a change in the properties of the engine lubricant.
A measured quantity of sample is placed in an evaporation crucible and heated to 250°C for 1-hour while a constant flow of air, controlled at 20 mm H2O vacuum, is drawn over its surface to remove the resultant vapors. The loss in mass of the oil is determined by weighing before and after the test and calculating the percent loss.
The Noack S2® is the second generation of the Selby-Noack, which was originally developed in the mid-1990s and the first Noack tester to eliminate toxic Wood’s Metal sample heating and allow for the collection of volatiles throughout the test.
