1.1 This practice covers a reproducible way to convert hardwoods, softwoods, herbaceous materials (such as switchgrass and sericea), agricultural residues (such as corn stover, wheat straw, and bagasse), wastepaper (such as office waste, boxboard, and newsprint), cellulosic feedstocks pretreated to improve suitability for fermentation, cereal grains, cereal grain fermentation mash, cereal grain fermentation beer, and fermentation residues into a uniform material suitable for compositional analysis. This practice is intended for samples that need to be dried prior to analysis.
1.2 Milling and sieving actions both produce large amounts of dust. This dust can be a nuisance hazard and irritant. Use appropriate respiratory protection as needed. If excessive amounts of dust are allowed to become airborne a potential explosion hazard is possible. Provide appropriate dust control measures as needed.
