Noack Test: Measuring Evaporation Loss in Motor Oils

Learn about the Noack test for volatility and evaporation The Noack Test is an important test used to evaluate the volatility and evaporation loss of engine oils and lubricants. It was developed in the 1950s by E.R. Noack and provides a measure of an oil’s resistance to evaporation at high temperatures. The test involves heating a sample of the oil to 250°C under nitrogen atmosphere for 60 minutes. The weight loss of the sample during this process is measured and reported as a percent. Oils with lower Noack volatility (weight … Read More
