Standard Test Method for Water Separation Properties of Light and Middle Distillate, and Compression and Spark-Ignition Engine Fuels

Importancia y uso:

5.1 The primary use of this test method is to evaluate new additive packages in specific fuels to ensure that fuel-water separability will not be compromised by the use of the additive package, either at their normal treat rates or at several times the intended treat rate to evaluate the impact of potential overtreatment.

5.1.1 Water Volume Changes—Using this technique reveal the presence of water-soluble components, such as alcohols, in the fuel.

5.1.2 Interface Condition Ratings—Using this technique reveal the presence of partially soluble components, such as surfactants, in the fuel.

5.2 Additives or contaminants that affect the interface could harm water separation properties of fuels in equipment and quickly inhibit the free flow of fuel through filters and injection equipment, causing a decrease in combustion performance.
