Research Report RR:D02-1713

    Research Report D02-1713 presents the results of the Interlaboratory Study used to establish the precision and bias statement for ASTM D7321, Standard Test Method for Particulate Contamination of Biodiesel B100 Blend Stock Biodiesel and Biodiesel Blends by Laboratory Filtration. The collaborative study included 7 labs who used method D7321 to analyze 8 samples. Sample sets included B5 and B20 blends and B100 samples derived from canola, soy, tallow and palm. Each sample set included 75% blinded samples. The sample sets were balanced such that each sample had equal blinded samples amongst the combined sample sets. All samples were coded such that the origin was known only by the ASTM statistician and the ILS coordinator. The research report presents summary method performance statistics as well as the measurement data used to calculate results for the study.
