Research Report D31-1013 presents the results of the Interlaboratory Study used to establish the precision and bias statement for ASTM D7674, Standard Test Method for Hexane/Petroleum Ether Extract in Wet Blue and Wet White. The collaborative study included 7 labs who used method D7674 to analyze wet blue samples using both hexane and petroleum ether as the extraction solvents. Samples were prepared under two condition: As received in wet state, diced; Oven-dried at two different temperatures, or air-dried, ground.
