Abstract:
Utilizing simple operation and world-class spectroscopic techniques, the new ASTM test method D8148 delivers the rapid, precise, and reliable haze and clarity determination measurement capability needed for today’s demanding petroleum and bio -based process control and product quality assurance applications. These applications include all light/middle distillate fuels (gasoline, jet and diesel) and biofuels. These materials are produced and transported in significant quantities and in each case the absence of haze, or product clarity, is an important quality control / workmanship requirement. Consequently, the determination and rating of haze and clarity in a wide variety of petroleum and biomass-based matrices is essential. After background and an introductory overview of the D8148 method, data is presented which demonstrates the power and flexibility made possible by this unique spectroscopic technology, provide updates on the latest ASTM activities and field testing as well as introducing the new portable insertion probe-based technique.
