This Method describes a means for determining the amount of fuel dilution present in an in-service lubricant. This is achieved by drawing into a surface acoustic wave (SAW) sensor vapor from the lubricant. Fuel vapor will be absorbed by the SAW sensors polymer coating. The amount of absorbance is then related to fuel content in the lubricant.
Currently there is no known standard for SAW-based fuel contamination detection in lubricants, even though this technology has been in-use for well over a decade for as a quick field-based tool. There are hundreds of units currently in use. Primary users are the US Navy, which originally developed the technology, for shipboard use, railroads, and analysis laboratories.
The title and scope are in draft form and are under development within this ASTM Committee.Back to Top
