Scope: To determine the ability of a fuel/water separator to separate emulsified or finely dispersed water from fuels.

The International SAE J1488_2010 Emulsified Water standard is a laboratory SAE standard specifically designed to measure a filtration system’s ability to remove emulsified water. For diesel fuel to pass the Standard and be considered within specification, the emulsified water concentration must be less than 200ppm. This SAE Standard uses very specific diesel fuel that is water-saturated to over 2000ppm. Reducing the water saturation by this much is no small task, especially as it must be done under strict laboratory conditions and over a pre-determined period. The minimum efficiency that a filter must attain to pass the SAE J1488 ver. 2010 is 92%. The Standard is recognized as the industry standard.
